{"title":"Lafferty Pressure Washer Foam Systems","description":"\u003cp\u003eLafferty pressure washer systems add foam and chemical spray to a pressure washer you already own. The injector sits on the washer outlet and draws chemical into the water, so no chemical passes through the pump. An airless foam wand makes clinging foam, and a bypass valve sends full pressure through the same hose to rinse. These systems suit fleet yards, mine sites and contract cleaners who already run a pressure washer and want foam without a separate wall station. They are built in stainless steel and use the same colour coded metering tips as Lafferty's wall units.\u003c\/p\u003e\u003ch2\u003eBuying guide\u003c\/h2\u003e\u003cp\u003eMatch the system to your washer flow.

A venturi injector draws each chemical through an interchangeable metering tip and blends it into the water, and no chemical passes through the washer pump. Quick connect the airless foam wand for clinging foam, using the fan nozzle for wide coverage up close or the zero degree nozzle to throw foam up to 7.6 m. For a chemical that should not foam, quick connect the spray nozzle instead.\u003c\/p\u003e\n\u003cp\u003eTo rinse, move the bypass valve across and fit your washer's own wand and nozzle to the gun.
