1/2″ FNPT- Molecular Sieve Filter Dryer Sight Glass Canister

Save your system from the hazards of water retention.  We assemble and pressure test all of our sieves ourselves, so you can be confident that you will receive a quality product that performs. This sieve weighs approximately 625 grams when full of dry zeolite.  It should weigh approximately 835 grams when the zeolite is completely full of material.


Description:  Our fully assembled  molecular sieve filter drier sight glass canister comes pre-filled with 4A zeolite absorbent to filter out and remove water and smelly sulfur compounds from your hydrocarbon gas streams.  This device is meant to replace your current “grenade” style recovery pump filter driers, and as such, it should be installed prior to the recovery pump’s inlet port.  The Sight glass makes it convenient and easy to know when the Zeolite needs to be regenerated or replaced without having to disconnect and weigh the canister it self. The 3″x 12″ sight glass canister is made from 304 stainless steel, sight glass and includes 1/2″ FNPT hemispherical end caps, two Viton 40 mesh internal screens gaskets, and two high pressure clamps.  This unit is pressure rated up to 150PSI. The canister is capable of holding 1 kilogram (2.2 lbs) of 4A zeolite, giving each canister the capability of trapping up to 210 grams of filtered material before needing to be regenerated or replaced with a new bag of 4A zeolite.
