Dry vacuum pumps may run continuously only with clean, dry air. Unlike other kinds of pumps, these may run at any pressure. Maintenance is extremely simple, and consists merely of replacing the vanes and cleaning the filters. The main areas of use include: suction cups conveyors, automatic machines, woodworking machines. Dry rotary vane compressors have no particular restrictions on their use, except the maximum operating pressure which may not exceed the rated value, this is why we always recommend using a safety valve.
