Hdf series drains feature a space-saving design and highly reliable automatic float controlled condensate drains for industrial compressed air treatment applications. Due the circumstance where the drain never runs completely dry, No air is lost during the discharge process. Hdf series condenste drains consequently lessen the waste of compressed air which has a positive effect on the efficiency of the whole compressed air system. Specifications media compressed air port measurement of 1/2 inch female discharge capacity 250 lph moc aluminum benefits complete air retention improved reliability due to large cross section outlet valve opening which minimizes the chance of blockage a low velocity condensate outlet ensures that no emulsion is created and supports installation of a static oil/water separato not required for as no, Electrical wiring The electrical supply is require hand-operated drainage valve for discharge and operational check fitted as standard
