High Density Carbon Pack Air Filters For Odor/Fume/Gas Removal

Activated carbon has been proven to remove and prevent odors and fumes from building up in recirculated air. Permatron offers two types of disposable, high density granular carbon pack air filters.

CWC Carbon Filter Packs

Granular carbon is contained in flexible nylon mesh that will not settle. Our CWC carbon pack offers gas phase, 60% minimum activity granular activated carbon with nearly 5 million square foot of surface area per pound for odor/fume removal.

CWB Carbon Filter Packs

CWB carbon packs contain two types of sorptive media, equal amounts of impregnated activated alumina with potassium permanganate and activated carbon bonded within a media for a uniform bed for light gas removal including ammonia, formaldehyde, hydrogen sulfide and sulfur dioxide.

Commercial Air Filters for Odor Removal

Both Model CWCPO300 and Model CWBPO375 are available with different densities of carbon, depending on the odor removal application. These air filters are sold in an unframed pad form, a framed pad option, or a framed prefilter, pad and afterfilter all together.

The 3 stage filtration styles are available with a ¾” polyester prefilter for particulates and polyurethane foam afterfilter to capture remaining particulates and prevent carbon from entering the system.

Moisture resistant beverage board die cut frame with stabilizer face grids and wire reinforcement are also available.

  • 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.

  • The filters we purchased are a great addition to our plant operations.  I am looking at other applications for their use…

  • The order process went very well.  We received the black washable fan bonnets 2 weeks ago and are very happy.  I will order again in the future.   Great product and great service.  Thank You!

  • 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.

  • The guys love them!  Clean look, and easy to clean….

  • 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.

  • 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.

  • PreVent is a very nice product, and very reasonably priced.  Belk is looking forward to the opportunity to do more work with Permatron in the future.

  • I had some good feedback from the client who uses our MH3 compact thermoelectric counter top cooler: • The filters are very easy to install. • They should help extend the life of the chillers. • They haven't had to replace any chillers that have the filters installed.
