PEM 15-3 Waterlevel Independent Partially Immersible Cascade Jet

PEM 15 Series jets are made of cast bronze, brass and copper. PEM 15 Series Water Level Independent Cascade Jets are designed for use with 'dirty' water as they can digest solids to the orifice size shown. These jets have the best foaming / white water spray effect in the lower sprayheights. The air intake has to be well above water level if the jets are immersed into a pool to avoid surge oscillating.
