Low pressure compressors

CT30 CT50 CT80 CT105 CT130 Series

New rotary lobe compressors, designed to operate with a maximum pressure of 2,0 bar absolute, or a vacuum rate of 50%.The CT range includes 5 different sizes with nominal air flow (at atmospheric pressure) from 300m3/h up to 1250 m3/h depending from the model. These compressors can be operated with the suction ports in vertical or horizontal position, clockwise or anticlockwise rotation, indifferently. The CT series lobe compressor main components are the cast iron housing CNC machined, two rotors (tri-lobe section) rotating without
contact between them and with the housing, two synchronized gears (driving the lobe rotors) and the mechanical seals. This type of pump is oil and maintenance free therefore grants to pump air or gases without polluting them with lubricating oil.When the pump operates, two consecutive lobes of each rotor move an air volume delimitated into a sort of a chamber, starting from the inlet port and thanks to the fine tolerance between the rotors and the housing internal surface. During the rotation this air volume is transferred to the outlet port, making possible a continuous air flow pumping which is possible to be raised or lowered by adjusting the pump drive speed. The CT series compressors are suitable for pumping a wide range of gases, apart from the explosives and the poisonous ones, due to the inevitable leakages.
