Tandem piston compressors ABAC

Two piston compressors integrated on one common pressure vessel
Oil-lubricated stationary compressors with V-belt drive, high air pressure of 11 bar
Two-stage compressor unit with two pistons
Robust cast iron cylinders for long service life
Variants on pressure vessels with volumes of 500 and 900 litres
Electric motors with inputs of 2 × 3 kW, 2 × 4 kW, 2 × 5.5 kW and 2 × 7.5 kW with a voltage of 400V/50Hz
Operation control by one common pressure switch, push-button switching
Oil level indicator for easy oil level reading
Pressure gauge to display the pressure in the vessel
Machine outlet via ball valve
Easy condensate draining via ball valve
Optimal solution for operations with significant differences in consumption, for covering power peaks or as an economical backup air supply solution in the event of a failure or maintenance on one compressor
