Most of the types of eductors therefore are to be installed between the water supply and the foam production equipment, according to the schematic below. The equipments performance depends on the attention given to the specific recommendations for each reference. The eductor should be positioned in such a way that after integration in the system, the hoses/pipes have a straight section of about 1 meter on both sides of the eductor. It is necessary to use an eductor adapted to the foam equipment, to take into account the pressure losses in the hoses/pipes and to provide a sufficiently powerful pump to get the reference pressure at the inlet of the eductor as well as at the inlet of the foam equipment. The pressure loss, or the differential pressure, between the inlet and outlet of the eductor, is 35 or 40%, depending on the model. The pressure loss in the hose/pipe connecting the eductor to the monitor/handnozzle must be calculated in depending on the length and the diameter of the hose/pipe used. Our range of eductors is either made of, new primary heat treated aluminium alloy with polyester coating or hard anodising, in bronze, in stainless steel, or in bronze and stainless steel, making them well adapted for use in a corrosive environment. All our eductors are equipped with couplings in compliance with international standards: Pump Water supply 1 m MINI. 1 m MINI. 1,5 m MAXI.
