Air Intake Protection

Environmental elements make air intake filtration a challenge. Out of sight, out of mind maintenance practices are something every rooftop unit falls prey to, causing a major headache or high cost repair for building management. Every piece of equipment, large or small, stationary or mobile, indoors or outdoors, needs preventative maintenance and air intake screen protection including quality commercial air filters. Airflow obstructions, like hail and dust can lead to costly expense and repairs to process, refrigeration, compressor and HVAC equipment.

Permatron manufactures PreVent with filter material that can prevent the coils from becoming impacted, prolong the life of the coils as well as help maintain the unit’s efficiency.

PreVent® Air Filter Screen for Cottonwood Protection

Dust, cottonwood seeds, environmental debris and are continually coating and insulating your equipment’s coils, condensers, electronic systems, motors, fins and other components that fall in the path of the equipment’s air intake. Even if foreign objects are not visible, the buildup of airborne particles will impact the equipment’s ability to work efficiently and require repeated maintenance for cleaning. Dirty equipment means efficiency decreases, heat build-ups, higher discharge pressure and increased amp draw. When forced to run for longer cycle times, at reduced capacity, the equipment eventually breaks down, life expectancy decreases and power costs escalate. Permatron’s patented equipment protection air filters catch debris before it can enter the air intake fins or louvers. Made of permanent, washable synthetic, UV protected fabric media, which draws in and traps airborne particulates. PreVent air intake screens are available with either electrostatic polypropylene media or a heavy-duty PVC coated polyester high abrasion media. Enhanced by airflow and custom fit, our air filters need no electrical connection or system modifications. PreVent air filters for intakes will not restrict air flow to the equipment.

Fast and Easy Installation with NEW MagnaMount®

Eliminating the need to drill into equipment, patented MagnaMount Air Intake Screen Installation mount clips contain a powerfully strong neodymium “earth” magnet that sticks to metal surfaces, allowing PreVent air intake screens to be repositioned as needed.  Patent No. US 10,180,265

HailStop® Hail Guard for Hail Protection

Some states average 1,000 hail events per year. These events cause millions of dollars of serious damage to HVAC equipment. Hail flattens fins and impairs operation. Bent fins on air conditioner coils can significantly increase your cooling costs. The reason for this is when the fins are bent, air cannot flow through the coil as efficiently. If the fins are bent severely enough, all airflow can be blocked, motors and compressors are strained and power consumption rises. Many multi-story buildings are designed so that air conditioning equipment can be placed on the roof shielded by decorative walls. However, that doesn’t mean that the air conditioner is adequately protected. Condensing units, chillers, cooling towers and exhaust fans can suffer damage from hail, lightning, and high velocity winds. HailStop Hail Guard Netting is an easy cut-to-fit retrofit solution that stops hail from flattening air intake fins.

Commercial Air Filter Preventative Maintenance Saves Money

HVAC systems can be the biggest challenge for facility management. They tend to be the most complicated system within a building, and make up the largest portion of the facility budget. Minor malfunctions tend to be the most noticeable among building occupants and processes. Well-maintained equipment costs less to operate, ensures optimal life expectancy and energy efficiency. By using the right commercial air filter, you can be sure that your equipment delivers consistent high-level performance and alleviates the need for unnecessary service calls and warranty claims. Permatron’s air intake products come in a wide range of models including flexible, rigid or 3-dimensional styles with various types of filter media that saves money in the long run, reduces downtime and enables a more predictable stream of financial outlays and maintenance costs.

Air Intake Problems

  • We had to change a combined condensing / free cooling coil because it was so badly damaged from debris and washing. 10k€ (approx. $12,000 USD)  for the coil and works and 6k€ (approx. $7000 USD) for the crane hire. The second chiller on the site is perfect as the screen was fitted back some time ago.

  • It’s always a great idea to protect HVAC condenser coils with screening, especially if you can do it right after new equipment installation. Once the magnets where inserted into the screen grommets, it took literally less than a minute to place the screening on the equipment, adjust it, done. This screening will protect the condenser coils from grass cutting, bugs, cottonwood seedlings, etc.

  • Our customer, Logoplaste, uses and raves about the Prevent BHA Screens and MagnaMount Kits.We did an install at their manufacturing facility in June on two units, all four sides required screens. Installation time was drastically reduced from the original 6 hour estimate with standard mount clips, to complete screen installation in under 1 hour with MagnaMount clips.The facility is located along the river where cottonwood trees are very abundant. Even when installing PreVent, it was catching the cottonwood that was flying. I brought him out one of your cleaning brooms a week after install, and the Maintenance Manager said that it is the best money he has spent since he has worked at that facility. He is planning on purchasing some more for his 4 Cooling Towers as well.

  • The PreVent bonnet style filter is the best thing I have ever bought to protect our cooling tower circular fan. We have to clean it every two weeks but it is so easy.

    Martyn RogersCotek Papers Limited, Maintenance Manager
  • Permatron's PreVent screening was installed on recently replaced 363A RTU condenser coils, outside air and economizer openings, using MagnaMount magnets to hold them in place VS drilling and screwing them on. The magnets will most definitely be our primary mounting option going forward. All three screens took us literally less than five minutes to install. I noticed how quickly cottonwood was caught by the screening.The screens can be cleaned in place or easy removed for more detailed cleaning.

  • I think that the plastic hail guard that Permatron offers is a great product. Because of the height and length it fits almost any piece of equipment on the market today easily. The ease of installation with your unique clips is great since it can only be correctly installed one way. This product allows contractors to offer hail guard at a reasonable price where quite often the end user wouldn't have any coil protection because of the cost of buying and installing expanded metal or a retro factory hail guard.

  • As a company who specializes in life cycle costing and energy efficient products in Seattle, we try to use the PreVent system whenever possible. We prefer to install our 4V style final filters without a pleated pre filter to maximize energy savings. This works very well except during our cottonwood season which can load up any filter in a matter of days. The PreVent system gives us the opportunity to remove the cottonwood seeds at a very low pressure drop. Having such a short lead time and being available in any dimension we require makes it an amazing addition to our product line and allows us to set our business apart in a very competitive marketplace.

  • I am very pleased to work with Permatron when ordering the PreVent Filter for installations in Wisconsin. From start to finish Permatron is very timely in getting pricing right down to delivery. The finished product is always as accurate as the drawings supplied to have it made. The finished product is also very easy to install, modify if needed, and cleaning is super easy. The fasteners are a great way to have the filter installed if you need to take down the filter to clean it. Otherwise, just turn off the air and either sweep it down or hose it off.

  • Several of our large commercial buildings in Atlanta have purchased the PreVent filtering product for their cooling towers. The benefits of being able to get through our spring season without much intrusion into the building owners equipment has been successful. The product was easy to install and has been simple for the customers to maintain. We are excited to have this product in our line of filtration options.

  • The R2 filters I have sold have worked very well. They do as advertised, by keeping the inside of our air compressors clean. No customer complaints after the sale and no problems with the construction of the washable filters. Your delivery times are fast and your customer service agents are a pleasure to work with. I look forward in continuing our business relationship with Permatron in 2013 and thank you for all of the continued support that we receive in making our compressors work better.

  • I have supported many customer with Permatron PreVent screens to protect cooling towers and air intakes. The BIG STUFF used to get into cooling towers throughout the year, yet not anymore. No more anxiety on those HOT DAY as coils will stay clean with PreVent in place. It has minimal impact on air flow while looking good to the eye, and a SLAM DUNK preventive maintenance buy for the coolers. With many simple mounting options, magnet, hook & loop and grommet, my customers have found more locations as they are so pleased with their original purchase. One Hillside customer changed his PREFILTERS every 5 weeks from POLLEN, and Permatron's PreVent has extended the life of his downstream filters. He now changes his prefilters every 6 months. Minimal pressure drop, big performance and simple mount options for an aesthetically eye pleasing solution is a product many Chief Engineers wish to show off. Thank you.

  • As you know, we offer your R2 magnetic filters as an option on our air compressors. The feedback from our sales people and customers has been very positive. The product is durable and offers a quality alternative to disposable filters. We are very pleased with the quick delivery times. In addition, the product does an excellent job keeping dirt away from the critical components on our compressors. As you probably know, compressors tend to be installed in the worst possible location. Just look for the hottest, dirtiest place in a plant and you will usually find the air compressor. Without the R2 filters our customers would experience greater service costs on their equipment

  • I just sent off an email to my manager giving him all the info from Permatron so he can get this out to the rest of our After Market Sales people. I told him how happy I am and so are the customers that I been getting your product out to. Thanks for all your help with my end.

  • I was not familiar with Permatron R-2 filters until I started working at Delta Industries. Now that I see how well the R-2 filters have been working I talk them up to my customers. A couple of our customers were so impressed the decision to apply R-2 filters to other applications such as water chillers and electrical control cabinets have proven successful. Industrial applications we have placed R-2 filters include machine shops, foundries, woodworking shops and even the CTA in a dusty bus garage. Other applications that have proven successful are shops that operate with open doors especially during the cotton wood and dandelion seeding seasons

  • I have 2 customer problems that I solved with your products. These are both hospitals. One had a problem with air filters being damaged by moisture being pulled into them by powerful air handlers. The filters were failing prematurely. I sold them your Model IN filters 3 months ago for one of their air handlers. They just ordered more filters for a second air handler. They have seven more air handlers that could use the same filters, so hopefully there will be many more orders for these filters.  The other hospital had a problem with leaves, insects and debris getting into their air intake louvers.  I sold them the PreVent air intake screen, custom sized, to protect their louvers.

  • As a new Territorial Manager in the Portland Oregon area for Total Filtration Service, Permatron gives me a great product and support that helps me find solutions for my customers. I live and work in an area where cottonwood is a killer on the mechanical equipment where larger debris needs to be stopped from entering a certain space. I can offer air filter solutions to my customer to help save them time and money. A few ways that the PreVent screens can help:

    • Save from having to do frequent coil cleanings because of cottonwood
    • Save from having to spend money on mechanical equipment break downs because the equipment wasn't protected from the harsh conditions
    • Save on labor costs from filter changes and maintenance cleanings promotes reallocation those labor hours to other critical projects
    I want to be valued as a total filtration representative to my customers (i.e., bakery facilities, city municipalities and mechanical contractors), and the PreVent benefits allows me to do so.

  • I attached a couple of photos of the completed PreVent Screens installed on Trane rooftop units. They fit very well to our dimensions and look good also. Your folks did a good job on matching all of our requested dimensions. I will keep you guys in our contact list as I can see several applications for your product that would be beneficial & it is another product we can offer to our customers.

  • I use the PreVent Model R filters with magnetic option that allows them to stick to the ironsteel surface of my Kaeser compressors, Kaeser air dryer and YASKAWA inverter on a Braun washer. I rinse with hot water once a week. These can be used in many applications and do save significant time for maintenancePM work. I also have installed this type filtration on all HVAC units. Easily eliminates 90% of lintdust that otherwise enters these areas

    Mark WearAramark Uniform Services, Oklahoma City, OK
  • I installed the HailStop coil guard today. My customer was pleased. I picked up a handful of gravel and thru it directly at the coil and it bounced right off. I was impressed. Will you get me a quote on another 3000 ft with hardware? I don't think that is going to be enough to do the entire job but should give me a good start.
