All Ice Qube Air Conditioners and most fan systems use PermaCool™ electrostatic filter media to keep dust and other industrial residues from clogging the condenser cooling air passages. The filter material is a rigid/durable 1/4" corrugated polypropylene media with 10 micron filtration which retains a low resistance to airflow. The filter will withstand harsh factory environments and will not degrade over time. Simple washing or vacuuming is all that is necessary to maintain the filter media over an indefinite period of time. PermaCool's dense 3 layer, 1/4" waffle weave configuration enhances its filtration abilities and creates a rigid electrostatic air filter. Unlike other media which may compress and restrict air flow, PermaCool™ retains its low resistance design.
For an additional cost, you may upgrade to a 4 micron electrostatic air filter for fine filtering.This electrostatic media air filter contains 3 layers of media. Layer one contains waffle corrugated black with blue polypropylene. Layer three contains black 12 mil huckaback woven polypropylene. Vinyl pull tab is installed in the center of one side for easy access.
Made of polypropylene, this filter has excellent strength and is very resistant to abrasion. It is light in weight and has smooth fibers that are easy to clean. Excellent resistance to most acids and alkalis. Good resistance to bleaches and solvents. Not attacked by mildew. Also good resistance to indirect sunlight and abrasion. Operating temperature 180 deg; Melting 325-350 deg F. UL Class 2.
