<\/a><\/div><\/div>Similar to the rotary vane and rotary piston compressors, the claw compressor is based on a static compression system. Inside the compressor housing (C<\/span>) two rotors (E, F<\/span>) in the opposite direction non-contact with very narrow gaps. They are synchronized via a precision gear. When the claw is over the suction port (B<\/span>) and the axial suction channel opening (D<\/span>) moves, the gas is sucked into the compression chamber. As the rotors rotate, the gas is transported from the suction side to the pressure side, where it is pressed or compressed between the rotors by reducing the volume until the lower rotor closes the opening of the pressure channel (G<\/span>) releases. The pre-compressed gas is fed through the pressure connection (H<\/span>) excluded. The heat generated by the compression process is dissipated by cooling air passing between the pump casing (C<\/span>) and a soundproof hood (A<\/span>) is sucked through.<\/span>
