Washable Non-woven Air Ventilation Filter

Overview
The housing of aluminum frame air filter is made of aluminum alloy materials which have excellent rustproof and waterproof performance. Aluminum frame air filter thus can be widely applied in pre-filters of all kinds of ventilation duct, air-conditioning, air compressor, etc.

We use non-woven fiber as material of filter media. Pleated structure increases the contact area of filter material with air so as to improve the efficiency of filtration. Filter material matched with welded steel wire mesh undergoes rust-proof processing, making the air filter stronger and more durable.
