The Airsept Refrigerant Canister Filter protects against A/C service equipment downtime due to debris and contaminants found in virgin refrigerant cylinders. The Refrigerant Canister Filter traps metal shavings and non-metallic debris. The filter should be installed inline between the refrigerant canister and the tank fill hose. The internal screen features a tapered design that forces debris to the side, ensuring that the center of the filter remains open for flow. According to the company, Airsept's Refrigerant Canister Filter uses superior sealing technology for leak-free performance. The filter features multiple O-rings and an OE-fit connector design, and it is available 1/2 Acme and 1/4” SAE flare. The filter is serviceable and replacement screens are available.
