Also known as rough filters or coil protection filters. Available from EU-1 to EU-4 as per European standards.Superior quality non-woven synthetic filter media, sandwiched between two layers of HDPE mesh which acts as a retainer and screens out large particles, thus, preventing them from being embedded in the media. The finer particles are filtered by the media.The pleating of the media enhances the filtration area for better efficiency. To eliminate the possibility of even a small amount of dirty air bypass, the media pack is securely bonded to the periphery of the enclosure frame using epoxy hardener.
