INTRODUCTION Thanks to many years of in-field experience regarding research, design and production of oil filters and oil separation for compressors applications, the high quality standard reached by FAI FILTRI has made it possible for the company to design and manufacture integrated groups equipped with oil filters and oil separators, thermostats and minimum pressure valves, suitable for assembly on rotary and screw compressors, which also allow a more and more accurate air cleaning in order to make it suitable for several industrial application such as: food industry, electronic,...

FILTERING ELEMENTS 5 bars collapse differential pressure tested in accordance with: Axial strain strength tested in accordance with Manufacturing compliance and first bubble point determination tested in accordance with : SEPARATION EFFICIENCY By avoiding overcoming suggested nominal flow rates it is possible to reach a residual oil waste lower than 13 ppm Oil residual in relation to speed and temperature Oil residual [mg/Nm3] Olio residuo [mg/Nm3] Flow velocity [m/sec] [m/sec] Velocità flusso OPERATING TEMPERATURES From –20°C to +110°C FLOW RATES Air/oil separation filter: With an...

FILTERING SURFACES Oil filter Filtering surface Filetring Surface COALESCENCE EFFECT The compressed air flux polluted by solid particles and micro drops of oil passes through the first layer of borosilicate micro fibers . At this stage micro drops, smaller than 1 micron , are agglomerated to form bigger drops according to the coalescence principle and are therefore collected and drained by the second layer of porous and synthetic material and end up, due to gravity, on the dry side of the separator. Coalescence principle diagram MINIMUM PRESSURE VALVE Setting: 4,5 bar The minimum pressure...

AIR/OIL SEPARATOR Thermostat operative temperature: See table for choosing the operative setting The thermostat is assembled on the GO / GSO integrated group on the oil filter side. When set up temperature is reached the oil flux is diverted for cooling by the radiator. VALVOLA TERMOSTATICA Thermostat 55°C o 71°C INIZIO CORSA: VALVOLA TERMOSTATICA Thermostat 55°C o 71°C INIZIO CORSA: PRESSURE DROP Air/oil separation filter: With nominal flow rate and 7 bars pressure the head pressure drop with a clean filter is up to 0,2 bars.
