The Durapac auto 2-speed power unit range is designed to deliver exceptional flow performance for applications demanding both speed and power.
The single-phase 08 Series, equipped with a universal motor, is ideal for field use with generators. The 1.5 kW single-phase models run on a standard 10-amp power supply, offering high flow rates in a compact, portable design. For medium to large tonnage cylinders and systems, the three-phase 3 kW and 4 kW, 400-volt models are an excellent choice.
All units feature an externally adjustable pressure relief valve and a variety of directional control valve options, making them suitable for operating single- and double-acting cylinders and tools. Additionally, an optional sub-plate style pilot check valve is available for enhanced functionality.
