Rotary vane vacuum pump FAPS series

oil-freesingle-stageair-cooled

The rotary compressor is made up of a cylindrical stator, inside of which a rotor, supported at its ends by two bases, rotates. This eccentrically fixed rotor has some slots where the vanes that slide over the internal surface of the stator are housed. The vanes form a set of cells, the volumes of which gradually increase from the intake port and which, afterwards, gradu- ally decrease down to the impulsion/drive port. When the rotor is rotating the vanes move outwards, under the action of the centrifugal strenght, and they get into contact with the internal surface of the stator. Our rotary vanes equipment is certified under ATEX directive 94/9/CE, which is required in order to allow installation in places where potentially explosive atmospheres may form. An explo- sive atmos-phere arises from the mixture of air with a fuel tak- ing the form of gas, vapour, mist or dust, in a proportion such that excessive temperatures, electrical arcs, sparks or other ignition sources, with sufficient energy, can lead to an explosion.
