Marine Air Filters | Corrosive Wet Environment Air Filters
Marine environments can be very unforgiving places when it comes to operating costly equipment and maintaining occupant safety and comfort. Tightly sealed vessels in a dark, damp atmosphere with wide temperature differentials can be an HVACR nightmare. Extreme weather conditions, sudden wind gusts and sea salt sprays all add to the corrosive environment. Make-up air or fresh outside air is limited, especially down narrow halls and stairwells leading to closed off lower rooms. Stagnate old air has no place to go and needs constant ventilation for recycling.
Airborne dust particles, bacteria, molds, yeast and VOC's can build up to be a serious problem. Washable polypropylene media air filters work extremely well in such an environment. Because the woven media of polypropylene is manufactured as a mono (single strand) filament, it does not have a porous surface. This means it will not absorb or retain moisture, and does not encourage the growth of mold, bacteria, viruses, yeast or fungi, which are all common complaints in the boating/shipping industry. Synthetic foams can be added to marine filters for greater arrestance efficiency. The ethers hold up very well in wet environments including salt water, and have historically been used for pond and water filters. Permatron's polyester PermaFlo® can also be added for filters needing greater surface area. All plastic filters are made to withstand corrosive environments, including thorough cleaning practices that include chlorine bleach.
A variety of durable frame options are available for corrosive environments, like rigid plastic, stainless steel or flexible vinyl edging.
