Dry Vacuum Pumps can run continuously exclusively with clean, dry air. Unlike other kinds of pumps, the dry rotary vane pumps can run at any pressure. Maintenance is very easy and consists of replacing the vanes and cleaning the filters.
The main application fields include: suction cup movements, automatic machines, woodworking machines. Dry vane vacuum compressors have no particular restrictions on their use, except for the maximum operating pressure which should not exceed the rated value. For this reason it is always recommended to use a safety valve.
These pumps consist of a rotor in an eccentric position rotating inside of a cylindrical body. This rotor is equipped with channelings in which the vanes are inserted. During the rotation, as a consequence of the centrifugal force, the vanes are pushed in contact with the body, creating close spaces that increase their volume beckoning air from the container to be emptied and expelling it from the outlet. If used as a compressor, the aspirated air is conducted to the outlet.
Oil-free rotary vane pumps can run continuously both at atmospheric pressure and at the highest vacuum. However, they cannot be used when the aspirated air contains moisture, oil or other liquids traces. At a certain pressure the rotary compressors benefit of supplying air without pulsations. Thus, they don't need a storage tank.
The main application fields include: suction cup movements, automatic machines for packaging, woodworking machines, wood presses, plastic material presses, banknote counting machines. In construction they are used in sprinkler for plaster, low pressure printing machineries, pneumatic conveyor systems.
Upon request it is possible to accessorise the oil free rotary pumps SC.60 140 with a FBX-S noise reduction box.
