PROAIR® three phase industrial air compressor units are designed and manufactured to ensure the continued efficient production of air with a minimum of maintenance.
Industrial design methods such as slow operating speeds, full cast iron pump construction, flywheel cooling, and the latest in valve design, are all employed to ensure that a cost effective air supply is always provided.
All compressor units will operate automatically according to your air demand, and apply the principle of reduced load starting to ensure long and trouble free service.
The 'SD' suffixed units have star delta reduced current starting and incorporate PROSTART which pneumatically unloads the compressor during the starting cycle
