Description

Automatic moisture control, heated operation, and a 1/4-inch check valve included with each trap. The ONAIR Automatic Drain Water Trap automatically releases collected moisture and includes a 12V heating coil for cold-weather air-ride applications. Every automatic trap now comes with a 1/4-inch NPT check valve for the tank-side connection, which is included in the updated price.

What is included?

  • Single water trap: one automatic-drain water trap and one 1/4-inch NPT check valve.
  • Dual water traps: two automatic-drain water traps and two 1/4-inch NPT check valves, one for each compressor line.
  • 1/4-inch NPT female trap ports, automatic moisture drainage, built-in 12V heating coil and 12V electrical connection.
  • The included check valve has 1/4-inch female-to-male NPT connections.

How the check valves work

For the ONAIR automatic-drain arrangement, a check valve is used on each side of the trap. Most compatible compressor leader hoses already have a check valve at the hose end. Connect that leader hose to the inlet of the water trap. Then install the included 1/4-inch check valve on the trap's outlet, toward the air tank. The tank-side valve helps prevent stored air pressure from flowing back through the trap when the compressor stops, allowing the automatic drain to operate as intended.

Typical air path: Compressor β†’ compressor leader hose with check valve β†’ automatic water trap β†’ included 1/4-inch check valve β†’ air tank.

If the compressor's leader hose does not already contain a suitable check valve, an inlet-side check valve is also required for this arrangement. For dual-compressor installations, use one trap and its included tank-side check valve on each compressor line.

Installation notes

Confirm that the existing compressor check valve is present and working. Follow the indicated airflow direction toward the tank, use pressure-rated components and compatible 1/4-inch NPT threaded fittings, and install the heating/drain wiring according to the applicable instructions. A 1/4-inch NPT thread size is not the same as 1/4-inch airline outside diameter; other airline sizes may need appropriately rated adapters. Verify the arrangement for your specific compressor and tank before installation.
