Float operated and entirely pneumatic, the CDV1 needs no electricity, no timer and no adjustment. It opens only when condensate is actually present, discharges it, and reseals, so not one cubic foot of compressed air is vented to atmosphere.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSelect your model from the dropdown above.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eWhy a Demand Drain Instead of a Timer\u003c\/h2\u003e\u003cp\u003eA timed solenoid drain opens on a fixed schedule whether there is condensate waiting or not, and every one of those open cycles blows compressed air straight out of the system. Across a plant running several drains around the clock, that lost air shows up directly on the electric bill as compressor horsepower you paid for and never used. A demand drain discharges on liquid level instead of on the clock. The float lifts, the valve opens, the accumulated condensate goes out, and the valve reseals before air can escape. There is nothing to program and nothing to tune seasonally.\u003c\/p\u003e\u003cp\u003eBecause the CDV1 is purely mechanical, it also keeps working during a power outage, needs no conduit run or receptacle at the drain point, and carries no solenoid coil to burn out.\u003c\/p\u003e\u003ch2\u003eModel Selection Chart\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eBowl Capacity\u003c\/th\u003e\n\u003cth\u003eRated Air Capacity\u003c\/th\u003e\n\u003cth\u003eInlet Port\u003c\/th\u003e\n\u003cth\u003eDrain Port\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCDV1-5\u003c\/td\u003e\n\u003ctd\u003e5 oz metal bowl\u003c\/td\u003e\n\u003ctd\u003e150 SCFM\u003c\/td\u003e\n\u003ctd\u003e1\/2\" NPT\u003c\/td\u003e\n\u003ctd\u003e1\/8\" NPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCDV1-32\u003c\/td\u003e\n\u003ctd\u003e32 oz metal bowl\u003c\/td\u003e\n\u003ctd\u003e250 SCFM\u003c\/td\u003e\n\u003ctd\u003e1\/2\" NPT\u003c\/td\u003e\n\u003ctd\u003e1\/8\" NPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eRated air capacity is the compressed air flow the drain is sized to serve.

It is a direct upgrade path for shops still draining receivers by hand with a petcock, and for plants trying to cut the compressed air waste built into legacy timer drains.\u003c\/p\u003e\u003ch2\u003eWhere the Drain Belongs in Your System\u003c\/h2\u003e\u003cp\u003eEvery point in a compressed air system where air cools is a point where water falls out of it. That means a drain belongs on the receiver, on each \u003ca href=\"https:\/\/aircompressorstore.com\/collections\/filter-housings\"\u003efilter housing\u003c\/a\u003e, on the \u003ca href=\"https:\/\/aircompressorstore.com\/collections\/refrigerated-air-dryers\"\u003erefrigerated dryer\u003c\/a\u003e sump, and at every drip leg. Condensate left in the system carries oil and rust downstream into tools, cylinders and finishes. Collected condensate is regulated waste in most jurisdictions, so route the discharge to an \u003ca href=\"https:\/\/aircompressorstore.com\/collections\/oil-water-separator\"\u003eoil water separator\u003c\/a\u003e before it reaches a floor drain.\u003c\/p\u003e\u003ch2\u003eInstallation and Service\u003c\/h2\u003e\u003cp\u003eMount the CDV1 below the vessel being drained so condensate flows to it by gravity, and pipe the 1\/2\" inlet with a full port isolation valve so the drain can be serviced without shutting the system down. Keep the inlet line short and free of traps. Once a year, isolate the drain, remove the bowl and flush out accumulated sludge and rust scale. Because the CDV1 has no electronics and no timer board, annual cleaning is effectively the entire maintenance program.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Air Compressor Store\u003c\/h2\u003e\u003cp\u003eAir Compressor Store is an authorized Champion Pneumatic distributor. Every CDV1 drain ships with the full factory warranty, lifetime application support, and access to our compressed air engineers for drain sizing and condensate system design.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eWhat does zero air loss actually mean?\u003c\/h3\u003e\u003cp\u003eIt means the valve never opens to atmosphere unless liquid is present to be discharged, and it reseals as soon as the liquid is gone. A timer drain, by contrast, vents compressed air on every cycle regardless of whether it had anything to drain.\u003c\/p\u003e\u003ch3\u003eWhich model do I need, the CDV1-5 or the CDV1-32?\u003c\/h3\u003e\u003cp\u003eSize on the air flow through the vessel you are draining. The CDV1-5 with its 5 oz bowl is rated for 150 SCFM and suits filter bowls, dryer sumps and smaller receivers. The CDV1-32 with its 32 oz bowl is rated for 250 SCFM and suits larger receivers and wetter duty, including humid summer conditions where condensate volume climbs sharply.\u003c\/p\u003e\u003ch3\u003eDoes it need electricity or compressed air to actuate?\u003c\/h3\u003e\u003cp\u003eNeither. The CDV1 uses the system pressure already in the vessel and a float to operate. There is no power connection and no separate control air line.\u003c\/p\u003e\u003ch3\u003eCan I drain it manually when I need to?\u003c\/h3\u003e\u003cp\u003eYes, on the CDV1-5. Order the CGRP-96-000 mechanical override, which mounts to the valve and gives you drain on demand by hand.\u003c\/p\u003e\u003ch3\u003eWill it work with synthetic compressor lubricants?\u003c\/h3\u003e\u003cp\u003eYes. The metal bowl is compatible with all compressor lubricants, which is exactly why Champion specifies metal rather than plastic on this drain.\u003c\/p\u003e\u003ch3\u003eHow high a pressure will it take?\u003c\/h3\u003e\u003cp\u003eUp to 200 PSIG.
