Spectra Pre Filter wraps are made from Filtrair's bv Netherland's superior high loft synthetic filter media. The wrap is designed to add a stage of pre-filtration on static cartridges and protect them from leaves, pollens, insects and other large airborne contaminants. Wraps can be installed/removed while the system is running. Spectrum also offers a specially designed hydrophobic wrapper which acts as a coalescer and prevents moisture, rain water, and mist from getting into the cartridge.
