Permatron DuraLo (Model DLO) is a washable polypropylene media air filter that works extremely well in wet environments, because the woven media of polypropylene is manufactured as a mono (single strand) filament. It does not have a porous surface, meaning it will not absorb or retain moisture, and does not encourage the growth of mold, bacteria, viruses, yeast or fungi. These are all common air filtration complaints in the boating/shipping industry. Containing our exclusive Accumulator Chamber® construction, this filter is designed to work in applications requiring very low resistance to air flow or high velocity air flow. Available in 1″ or 2″ thickness, the filter media is encased in a front and rear black plastic grid for added support, framed in stainless steel.

Initial Resistance: 0.05" w.g.

5 Year Warranty

Nominal sizing (1/2" undercut on L x W, standard for filter sizing)

Custom sizes and bulk pricing available, please contact us with your request.

This filter does not remove salt from the air, the filter itself is resistant to the effects of corrosive environments.
