HF-500 Hydro-Foam Self Inducing Nozzle
The HF-500 unique design, with built in inductor, allows it to be attached to any existing fixed monitor, portable monior, or deck gun. When the need arises for high application rates of AFFF, simply inserting the pick-up hose into your foam supply produces an instant AFFF foam system.
The HF-500 is factory set with 3% metering washer. A 1% washer is also provided. Without either washer the rate of induction is approximately 4.8%.
The HF-500 nozzle is constructed of rugged brass alloys. The nozzle tip turns on a cam mechanism to wasily change stream patterns.
