ABSTRACT:
A foam generating nozzle construction, and method of use is disclosed, wherein a tubular nozzle body, with an inlet and outlet has turbulence inducing means in the form of contiguous transverse apertured plates preceding air aspirating means. A pressurized mixture of water and foaming agent enters the nozzle and diverges through a first set of apertures in an obstructing plate, then converges through a contiguous plate with a central aperture partially overlying the first set of apertures to create a turbulent spray which then entrains air from aspiration holes to produce a low or medium expansion foam with an enhanced drain time.
