Poweramp’s CentraAir Series air powered dock leveler features an automotive grade bellows system which has the same technology used in air-ride suspension systems throughout the trucking industry. It utilizes existing shop air or a dedicated compressor. It can also be run manually via a lanyard control located at the back of the leveler or can be push button operated. The low amp draw at each dock (zero - .07amp) will produce “first cost” savings over conventional push button leveler systems. The CentraAir is suited for conveyer loading applications where air is readily via existing shop air or a dedicated compressor. Multiple units can run off a single air supply and off reserve air (with lanyard control) during power outages.
