Activated carbon is an effective way to remove and prevent odors / fume buildup in recirculated air. Permatron offers two types of disposable, extended surface carbon pleated air filters, with 60% activity granular activated carbon. This 1″ pleated type filter has approximately 3X the effective carbon media surface of our ¼” panel filter.
Activated carbon with alumina and 5% potassium permanganate should be used for light gas removal, including ammonia, formaldehyde, hydrogen sulfide and sulfur dioxide.
Permatron’s custom air filters feature high performance 100% synthetic air filtration media that is pleated and impregnated with activated carbon to allow total media usage, maximum air flow and high dust holding capacity.
The air filter media is bonded to expanded metal support grids to prevent sagging, air bypass and media flutter. These custom filters are encased in moisture resistant beverage board frame with diagonal and horizontal support members
I'd like to take a moment to thank-you for your support, your quick replies and your thoroughness throughout 2012. It has been a pleasure working with you and your team and I look forward to doing so again in 2013.
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.
