Suttner ST75-2 Foam Head

The Suttner ST75-2 Foam Head is the upgraded version of the popular ST75, offering even greater foam control and consistency for high-demand cleaning applications. Purpose-built for roof cleaning, truck washing, softwash, agriculture sanitising, and food industry use, this heavy-duty foam head produces thick, stable foam that sticks—maximising chemical dwell time and coverage.

Made in Germany by RM Suttner, the ST75-2 is designed for precision chemical-air-water mixing, delivering excellent results in any foaming application where efficiency and control matter most.

Like all high-performance foaming gear, the internal setup of the ST75-2 must match your pump’s flow rate. The internal orifice and jet size are critical for generating quality foam without losing pressure or causing backflow.

Suttner ST75-2 Foam Head – Next-Level Foam for Professionals

The Suttner ST75-2 is a professional-grade foam head that takes the performance of the original ST75 to the next level. Its enhanced design offers finer air/chemical control and more stable foam, ideal for demanding applications like roof treatments, vehicle fleet cleaning, and food-safe sanitising.

This unit is not a chemical injector and is not intended for downstream injection via venturi action. Instead, it’s a dedicated foaming head that works in conjunction with a foam lance or other foaming setup, mixing air, water, and chemical with precision.

Because it’s designed for specific flow rates, the internal jet and nozzle sizes must be chosen based on your water blaster’s litres-per-minute output. If you use an incorrect size, you may experience poor foam or pressure issues. That’s why we always recommend giving us a call first—so we can set it up to suit your machine exactly.
