Suttner ST-75 Brass Foam Head 4,000 PSI with #8.0 Air Injector Nozzle and 1/4" F Inlet. The ST-75 produces thick foam for an easy and safe application and to save on chemical usage by reducing splash and drift of chemicals

Features
• By means of the foam head ST-75 different foam applications are possible as the air injector nozzle is easily exchangeable and adaptable
• The flat spray nozzle can be infinitely adapted from the vertical position to the horizontal one
• The maximum flow is dependent on the chosen nozzle size
• By means of the integrated air injector in the foam head the air is sucked in on the face side
• Independent of the length of the lance a constant foam quality is guaranteed
• The spraying result is especially even as a high quality foam nozzle insert is used
