What is the difference between this unit and the SMU-20/1-GR-FD-R?
This version features two separate foaming functions (F/1 and F/2) instead of a disinfection function, offering more flexibility for using different cleaning agents.
How do the two foaming functions work?
Both foaming functions operate at the same compressed air pressure and can be used separately for different cleaning applications.
Is there a model available for use without an external air supply?
Yes, the SMU-K-20/1-GR-FF-R is equipped with an integrated compressor for locations without compressed air connection.
How is the unit operated?
Operation is done via an electromechanical switch, allowing easy selection between rinsing and foaming modes.
Can this unit be supplied with a hose reel?
Yes, a manually retractable hose reel can be added as an option.
