These are the heavy end of the condensate drain range: a level sensing, zero air loss drain that dumps the water and closes again without blowing compressed air down the sewer with it.\u003c\/p\u003e\n\u003cp\u003eA timer drain throws away air on every cycle whether there is water in the tank or not, and on a plant sized receiver that is real money across a year. A zero air loss drain only opens when there is condensate to discharge. These are also pneumatically operated, which means no electrical supply to run and nothing to fail in a wet, cold or classified area.\u003c\/p\u003e\n\u003ch3\u003eModels\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eS0910, Drain-All DH50-0LAAA:\u003c\/strong\u003e pneumatic zero air loss drain, 1\/2 in NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eS0920, Drain-All RH50-0LAAA:\u003c\/strong\u003e the Rust Handler model, pneumatic, 1\/2 in NPT\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnections:\u003c\/strong\u003e 1\/2 in NPT inlet and outlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation:\u003c\/strong\u003e pneumatic, no electrical supply required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum operating pressure:\u003c\/strong\u003e 40 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDischarge rate:\u003c\/strong\u003e 1.5 GPM at 100 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCycle time:\u003c\/strong\u003e 10 seconds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrain type:\u003c\/strong\u003e zero air loss\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCheck the maximum working pressure on the unit data plate against your receiver before installing.

The 1\/2 in port also keeps them from blocking the way a 1\/4 in drain does on a dirty old receiver.\u003c\/p\u003e\n\u003ch3\u003eInstallation notes\u003c\/h3\u003e\n\u003cp\u003ePipe the drain from the lowest point of the tank with a full size take off and an isolating ball valve ahead of it, so the drain can be serviced without blowing the receiver down. Keep the discharge line short and sloped, and do not reduce it below the outlet size. Condensate off a reciprocating compressor is oily and acidic, so it belongs in an oil water separator rather than straight into a floor drain.\u003c\/p\u003e\n\u003ch3\u003eRelated parts\u003c\/h3\u003e\n\u003cp\u003eWe also stock electronic automatic tank drains in 1\/4 in through 1 in NPT, Kingston and Conrader pneumatic drains, float drains, pull cable drains, pet cock drains and the Champion automatic drain repair kit.\u003c\/p\u003e\n\u003ch3\u003eNot sure which model\u003c\/h3\u003e\n\u003cp\u003eTell us what is on the machine now, the receiver size and whether the condensate is carrying rust, and the Warthog Air Compressor Store team will confirm which of the two you want before you order.\u003c\/p\u003e\n\u003cp\u003eDrain-All DH50-0LAAA and RH50-0LAAA Rust Handler pneumatic zero air loss automatic tank drains in 1\/2 in NPT for air receivers and wet tanks.\u003c\/p\u003e","brand":"AirComParts","offers":[{"title":"DH50-0LAAA","offer_id":67721350185235,"sku":"S0910","price":1444.49,"currency_code":"USD","in_stock":true},{"title":"RH50-0LAAA Rust Handler","offer_id":67721350218003,"sku":"S0920","price":1279.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/aircompressorstore.com\/products\/drain-all-pneumatic-zero-air-loss-automatic-tank-drain-half-inch","provider":"Warthog Air Compressor Store","version":"1.0","type":"link"}
