Running a compressor at less than full load results in a drop in compressor efficiency and thus an increase in operating costs. Moisture Separator A device that separates condensate from an air stream. Mole Amount of substance in elementary entities as atoms. Molecular Sieve A regenerative desiccant. The pressure that a gas will have if it occupies the total volume of the gas mixture.
Atmospheric pressure is stated in psia.
Pressure at some reference point as measured with a gauge and dependent on atmospheric pressure. In the process the outgoing air is reheated by the incoming air. Pressure Force per unit area. Pressure drop Loss of pressure in a compressed air system due to friction or restriction. Knowing the required PDP is critical for the proper sizing and operation of your Dryer.
