Siphon Spray Gun for Air and Water

The Guardair 79WGD is a pistol-grip siphon spray gun built for air and water applications. It uses a tube siphon mechanism and accepts a standard garden hose for liquid supply. The lever-style body provides direct flow control during spraying tasks.

12-inch Extension with NPT Air Inlet

A 12-inch nozzle extension places the spray pattern at a practical working distance. The female NPT air inlet connects to shop air lines without adapters. Gray finish resists visible wear in workshop environments.

Check Air Supply and Hose Compatibility

Verify your compressor delivers 15 cfm at the required pressure for continuous operation. Ensure the garden hose thread matches the siphon inlet for a secure liquid feed. The gun has no integrated canister, so liquid is drawn directly from the connected hose.

Questions about this item

What does the 15 cfm air consumption mean for compressor sizing?

The gun draws 15 cfm, so the compressor must supply at least that volume continuously at the required pressure.

How long is the extension and what inlet does it use?

The extension measures 12 in and connects via a female NPT air inlet.

What steps are needed to start the siphon action?

Fill the tube with liquid, attach the air supply, then pull the lever to create suction and begin spraying.
