Why You Need to Change Your Plant’s HVAC Air Filters Regularly

industrial filter supplier in RichmondAs an industrial plant manager, even though you’re dealing with heavy machinery and lots of raw productive power, you know that your plant is actually a pretty delicate operation. If the slightest thing goes wrong, you could end up losing out on precious hours, or even days, of operating time – which could translate into big revenue losses.

A plant is only as strong as its weakest link, and if you haven’t made the time to get your air filters checked out recently, there’s a good chance that your weakest link is about to snap.

Protect Against Internal Pollution
If it’s been a while since you’ve replaced your plant’s air filters, you need to get in touch with an industrial filter supplier in Richmond today. Your air filters don’t get nearly the attention they deserve, since they need to be able to process and filter thousands of cubic feet of air every single day.

After a while, your air filter will start to get full of pollutants, and it won’t be able to do its job effectively. This means that all of the impurities that are in your air, including industrial pollutants, chemicals, dust and debris, and even mold spores, will go right past your filter and can be inhaled.

Keep Your Air System Safe and Efficient
A dirty air filter doesn’t just expose you and your team to harmful pollutants; it also makes your HVAC system have to go into overdrive just to move air through the ducts. This means that you’ll end up literally wasting money on heating and cooling, simply because the system isn’t operating at a high degree of efficiency.

In the high-pressure business climate of today, you simply can’t afford to float any useless expenses; therefore, it’s imperative that you ensure your air filters are in good shape.

How to Protect Your Plant from Internal Pollution

industrial air filtration systemWhen you’re in charge of managing an industrial plant, you should know the importance of maintaining high safety standards. Following proper safety protocols not only keeps you and your team safe, but it prevents the loss of revenue created by work stoppages due to accidents.

While you probably make sure to adhere to major safety standards with regards to your machinery and your personnel, you probably overlook the safety of your HVAC air systems. This is understandable, as lapses in air filtration maintenance usually don’t create the kind of high-level emergencies as other safety lapses.

However, if you’re not paying attention to the possibility of internal pollution in your plant, you could be setting yourself up for some major losses down the line.

Air Filtration Maintenance
In order to make sure that your plant is operating with the highest safety standards, you need to pay serious attention to your industrial air filtration system. When your air filtration system is working properly, it’ll remove pollutants from the air and keep a good air circulation going inside your industrial plant.

However, in order for your filtration system to function this way, you need to make sure that you get your filters changed regularly, and that your whole HVAC system is checked and cleaned annually.

Keep Your Air Clean
A dirty air filtration system can create internal pollution by allowing chemical pollutants, dust, molds, and other impurities to cycle and recycle into your plant’s air. Over time, these pollutants can compound, causing pollution to severely worsen.

This can have serious health impacts on you and your team, and could even open you up to legal liability if one of your employees becomes ill or injured. Make sure you’re avoiding internal pollution by checking your air system regularly.

Food and beverage processors in the United States and abroad
operate under some of the most stringent standards relating
to food safety. The Food and Drug Administration (FDA),
International Featured Standards (IFS), Safe Quality Foods (SQF),
British Retail Consortium (BRC), and 3-A Sanitary Standards, Inc.
(3-A), respectively, all set forth standards that must be met at the
risk of production shut down.
Two areas of increased evaluation are the use of sterile
compressed air and culinary steam in the food processing
industry. While the language surrounding the various standards
differs slightly, from “unlawful indirect food additives” to
“monitored for purity,” it is—at its core—about protecting
manufacturers and consumers.
Understanding and navigating industry standards means
understanding the roles of sterile compressed air and culinary
steam in the industry and your facility.
Sterile compressed air is an indispensable part of the
food manufacturing process, because it is used for mixing
ingredients, storing products under positive pressure (to prevent
the ingress of contaminants), pumping viscous products through
pipelines, bagging or packing products, rejecting sub-standard
products from conveyors, and blowing food and other debris off
work surfaces and production equipment.
Unfiltered compressed air contains particulates, oil and water
aerosols, and bacteria. These undesirable contaminants must
be removed from the manufacturing process in order to ensure
product safety and consistency. So, what can be done to filter
compressed air?
Years of engineering and testing have shown that a three-stage
filtration system is ideal for producing sterile compressed air on
demand at the various points-of-use. The three-stage system is
able to provide the sterile-level removal efficiencies required in
the industry while minimizing the change out frequency of the
more expensive sterile filter. (See Illustration A.)
Filter #1 should be composed of relatively open or “loose” media. This configuration allows for the removal
of large amounts of water and rust that typically contaminates the lines after refrigerated drying equipment.
The open media prevents the filter from becoming blocked too quickly. Higher-end filters will use a binderfree
fibrous media that is both hydrophobic and oleophobic. This allows the filter to quickly shed water and
produce high flow rates at a lower pressure loss, minimizing energy consumption.
Filter #2 should remove all remaining water and oil aerosols as well as any particles that may have
penetrated the first filter. Because the second filter needs to have greater capture efficiency than the first
filter, the ideal filter should incorporate a pleated media structure. A pleated structure produces greater
media surface area, which reduces the pressure loss and increases service life by providing more dirt
holding area than non-pleated media.
Filter #3 is designed to capture microorganisms and reliably withstand the extreme conditions of steam
sterilization. Filtration media made of PTFE membrane or borosilicate is often the best choice because it is
highly resistant to steam and can be very tightly controlled to produce a bacterial-retentive structure that
remains effective over the entire service life. Since this filter should not encounter any dirt or oil, choose a
version that can tolerate a high number of sterilization cycles. This filter should be rated at >99.9999998% at
0.2 micrometers because this is the size of some of the smallest bacteria. This is also the approximate size
that corresponds to the lowest-efficiency point of most depth filters.
Illustration A. Recommended Compressed Air Filtration
In the food-processing industry, culinary steam is direct injected into food for cooking or used indirectly
to clean and sterilize vats, mixers, conveyors, and other equipment used in the food-production process.
Culinary steam is defined by 3-A Accepted Practice 609-03 as “steam that is free of entrained contaminants…
and is suitable for use in direct contact with food products, other comestibles, and product-contact
The primary safety concern is that un-filtered steam can contain contaminants including rust and dirt
that could end up in the food product. Unfortunately, a major source of contamination is often the steamgeneration
process itself, especially in systems where excess steam is condensed, recirculated, and reused
in the process. This “recirculated condensate” can be contaminated with pipe scale and suspended solids,
as well as oils and metallic debris shed by the pumps in the recirculating system. If the steam is not filtered
before use, these contaminants can make their way into the food product. So, what can be done to generate
culinary steam?
There are two critical stages of a culinary steam filtration system: a final culinary steam filter in addition to
a pre-filter or entrainment separator. (See Illustration B.) Point-of-use filter housings designed with stainless
steel, free from imperfections such as pits and crevices, is ideal for producing culinary steam. Culinary steam
filtration should be installed at all points-of-use because any piping downstream of your final filter could
create additional opportunities for contaminants to enter the system.
Filter #1, often referred to as the steam pre-filter or an entrainment separator, should effectively remove all
particulates 10 μm in size or larger from the production line’s incoming steam source.
Filter #2, identified as the point-of-use culinary steam filter, should remove 95% of particulates 2 μm in size
and larger.

Additionally, filtering your culinary steam will significantly reduce your plant maintenance costs. Unfiltered
steam can coat heat exchangers producing an undesirable insulating effect which can slow heat transfer and
increase production times. The proper filtration system will also remove dirt, rush and scale that can abrade
pumps, valves and other hardware causing premature equipment failure.
As interest over consumer and product safety standards continue to grow, food and beverage manufacturers
around the globe can expect increased attention on the food safety standards and processes within each
facility. Protecting your customers—and your business—by verifying that your production processes are in
compliance with current regulations will help mitigate those concerns.
If you’re not sure whether your current sterile compressed air or culinary steam filtration system meets the
latest standards, contact a filtration consultant specialized in serving food and beverage processors

Water/Particulate Breathers

Water/Particulate Breathers

The Eaton tank breather filters “breathe” air in and out as the oil level rises and falls. The filters prevent the penetration of contamination from the ambient air in the hydraulic fluid. This circulating air contains articles and moisture that can cause corrosion, increase equipment wear, and reduce fluid performance. In typical systems, the internal hydraulic fluid is warmer than the external environment. This difference in temperatures causes water vapor to form. Breathers protect your hydraulic system by filtering out damaging moisture and particles.

The Importance of High-Quality Filtration Systems for Breweries

If you’re an independent brewer, you know that nothing is more important than creating a
high-quality product. After all, if you’re going to compete with the big corporate beer companies, you need to offer the kind of unique, robust flavors that will keep your customers coming back for more. Building a connection with your customer base is everything, and that connection lives and dies with the quality of your beers. In order to make sure that you’re selling only the finest beer that you can possibly brew, you need to make sure that you’re running your product through the highest-quality filtration systems that you can get.

Creating a Quality Product
If you haven’t done it already, make sure to look into installing Donaldson filtration systems in your brewery today. The process of brewing beer inevitably will lead to certain impurities getting into your brew. These can cause the beer to become cloudy with an impure, hazy appearance, which will be a huge turn-off for many of your customers. Even a small amount of impurities can collect at the bottom of a bottle, which will put a bad taste in your customers’ mouths. A good, reliable filtration system will keep all this junk out of the brew, so that you can offer up a high-quality beverage with the utmost confidence.

Saving Money
In addition to building up customer satisfaction in your product, a good filtration system will also keep the impurities out of your brewing and bottling systems. These can cause a hazardous amount of buildup in your taps and containers over time, which can eventually cause serious damage to your equipment. At the very least, you’ll end up losing time having to clean things out regularly. Install a quality filtration system to keep the mess away from your equipment and keep your brewery running smoothly.

Why Proper Air Filtration Can Save Your Business Money

When you’re in charge of an industrial manufacturing company, you know how important it is to run your business with as much efficiency as possible. The industrial manufacturing sector has been hard hit by economic shocks in the past few decades, and only the well-run and efficient plants will be able to survive while the competition falters.

hvac air filtersIn order to make sure that your profit margins remain robust, you need to make sure that you aren’t having any unnecessary cost overruns in your industrial operation, and you need to cut costs at every possible junction. One of the biggest areas where you could be spending unnecessary money is one area that many plant owners fail to pay any attention to: your HVAC system.

Energy Efficiency
If you haven’t taken the time to look at and evaluate your HVAC air filter housing and the rest of your HVAC system, you should take the time to do so soon. An inefficient or dirty HVAC air filtration system can cause your business to bleed significant amounts of money over time. A dirty HVAC system will not heat or cool your property efficiently, and it will block the airflow in the heating and cooling system. This will lead to you spending money on energy that is doing absolutely nothing to heat or cool your plant, which is an unacceptable expense.

Limit Liability
In addition to energy efficiency, a clean and reliable air filtration system will limit your exposure to legal issues that could arise from employees being exposed to harsh industrial pollutants. Pollutants are a natural byproduct of the industrial process, and if you spend the money necessary to make sure that your employees are kept safe from these pollutants, you’ll limit the possibility of an employee suing you after becoming injured from pollution exposure.

How Your Manufacturing Facility Can Generate Less Waste

When exploring water treatment filtration options for your manufacturing facility, there should industrial filter supplierbe an area of concern pertaining to water conservancy and water supply (especially freshwater). With emphasis on this as well as reducing the environmental impact from waste, it is important that all industries take another look at their manufacturing processes. As you research the options among newer and ‘greener’ filtration technology, you may find the cost reduction resulting from a new system to be surprising.

There are two routes to take when seeking more efficient water treatment filtration options. One is to use equipment that simply requires less fresh water; the second is to reuse water when the amount used is mandated by the process equipment. With this trend, you’ll see reduced costs for the purchase and treatment of fresh water, heating process streams, and waste treatment.

In addition to minimizing these overall maintenance costs, other factors to keep in mind are labor costs, potential production loss, and conversion or recovery of valuable products during both scheduled and unscheduled downtimes. While much of this can seem overwhelming, there are some easy methods you can use to determine whether your current filtration system needs an upgrade. Contact a industrial filter supplier for additional assistance.

What to Consider When Changing HVAC Equipment

hvac air filterIn order to make the right decision about the equipment they use for air filtration, it’s crucial that building owners, managers, operators, and maintenance personnel have access to reliable and accurate information about their options. Proper and in-depth research is a must, as effective air filtration will improve overall indoor air quality and promote a healthier and more productive work environment.

While the initial purchase price of industrial HVAC air filters can widely vary, it’s also important to consider all the factors that will be involved in the total lifecycle of the product. Overall, the total cost of ownership for any air filter can also be affected by costs associated with shipping, storage, operation, replacement, and disposal of the product.

Filtration Requirements
Filter selection must be based on the filtration requirements of the building where they will be used. For example, a building that operates industrial equipment will have different requirements than a medical facility where pure air is crucial. Take note of your new filter’s MERV (minimum efficiency reporting value) rating – this tells you what size particles the filter is capable of capturing, and what percentage of them it will remove from the air.

Operating Conditions
When replacing your HVAC system or air filters, also consider the operating conditions of both your unit and the building. For example, if there’s a leakage of air through imperfections in your building’s structure, it could mean that filtration efforts will need to be increased. If there is a leakage in ducts of filter bypass, the level of filtration will also not be optimal.
