The ST-75 has a larger orifice than a rinse tip, so snapping it on lowers the pressure, and the injector starts pulling soap through its pickup tube. As the soapy water passes through the nozzle, air is pulled in through the side ports and whipped through the stainless foam pad, producing thick foam. Swap back to your rinse tip and the pressure rises, the injector stops drawing, and you rinse with clean water.\u003c\/p\u003e\n\u003cp\u003eThat's why orifice size matters: too small, and the pressure stays high and the injector won't draw. We size it to your machine so it works.

It needs a downstream chemical injector, such as the Suttner ST-160, ST-164, or ST-167, to supply soap to the water stream.\u003c\/p\u003e\n\u003ch3\u003eIs this the same as a foam cannon?\u003c\/h3\u003e\n\u003cp\u003eNo. A foam cannon has its own soap bottle that you refill. The ST-75 foams soap that your downstream injector draws from a pail, drum, or tote, so there's nothing to refill at the gun.\u003c\/p\u003e\n\u003ch3\u003eWhy do you need my PSI and GPM?\u003c\/h3\u003e\n\u003cp\u003eThe orifice has to match your machine's flow and pressure. Too small and the injector won't draw soap; too large and you lose foam quality. We call after every order to size it correctly.\u003c\/p\u003e\n\u003ch3\u003eWill it fit my gun?\u003c\/h3\u003e\n\u003cp\u003eIt fits any gun, wand, or lance with a standard 1\/4\" quick-connect socket.\u003c\/p\u003e\n\u003ch3\u003eCan I use it with hot water?\u003c\/h3\u003e\n\u003cp\u003eYes, up to 212°F. You'll get the best foam at 130°F or less. On hot water machines, replace the foam pad periodically if scale builds up.\u003c\/p\u003e\n\u003ch3\u003eWhy isn't it foaming?\u003c\/h3\u003e\n\u003cp\u003eCheck that your injector is drawing soap, the pickup tube and strainer are clear, and the soap is mixed at the right strength. A clogged foam pad or air ports can also reduce foam; rinse them with clean water.\u003c\/p\u003e\n\n\u003ch2\u003eComplete Your Setup\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/single-chemical-injector-foam-wash-system\"\u003eSingle Soap Wash System\u003c\/a\u003e with the Foaminator foam lance\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/dual-chemical-injector-foam-wash-system\"\u003eDual Soap Wash System\u003c\/a\u003e for two-step touchless soap\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/touchless-1-2\"\u003eTouchless 1 \u0026amp; 2\u003c\/a\u003e truck wash soap\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cem\u003eImage Wash Products (Formerly Reflections Wash Products)\u003c\/em\u003e\u003c\/div\u003e","brand":"Image Wash Products","offers":[{"title":"Default Title","offer_id":67600435445990,"sku":"SS-TA-FM-NB","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0015\/4196\/3828\/files\/suttner-st-75-foam-nozzle-quarter-inch-quick-connect.webp?v=1790776710","url":"https:\/\/washproduct.com\/products\/suttner-st-75-foam-nozzle-quick-connect","provider":"Image Wash Products","version":"1.0","type":"link"}
