The WD-20 and WD-21 self-induction foam-water monitors are available in PL24, PL32, PL40, PL50 and PL64 models, with published flow rates from 20 L/s to 64 L/s. They are designed for foam-water firefighting and can be supplied with or without a foam-concentrate pickup tube, depending on the selected configuration.

The nozzle is made of stainless steel. The monitor provides 360° continuous horizontal rotation and vertical movement from -60° to +70°. Its two-row brass ball-bearing arrangement supports movement around the horizontal and vertical axes, while the handle and manual lock allow the operating position to be secured.

The WD-20 and WD-21 are suitable for industrial sites and fuel-related hazards where a foam-water monitor is required. The foam-concentrate supply and proportioning arrangement must be matched to the application.
