Hydro-Pac
LX SERIESTM Low-Pressure Gas Compressors were developed for a variety of industrial and research requirements. These LX SeriesTM compressors are available as single or two-stage models and feature the same proven design that made Hydro-Pac high-pressure compressors so reliable.
Standard models are rated 1500, 3000, and 6000 psi, and 3 to 40 hp. Larger, higher capacity models are also available. Simple modification allows customization for specific pressures, capacities and applications.
LX SERIESTM compressors are based on our hydraulically driven compressor technology proven reliable and easy to maintain in installations world wide.
HOW COMPRESSORS WORK
Features
Hydro-Pac LX SERIESTM Low-Pressure Gas Compressors feature:
- Oil-free non-lubricated design.
- Long slow stroke results in longer packing and check valve life.
- LX SERIESTM compressors take full advantage of a wide range of inlet pressures.
- Patented free piston design allows easy replacement of high-pressure seals.
- Efficient operation does not require plant air.
- LX SERIESTM compressors can be started under full load without unloading valves.
- Externally mounted hydraulic pump simplifies adjustment and maintenance (5 hp and larger).
- Capacity control is achieved through the drive mechanism.
- Design ensures positive and accurate alignment.
- Water cooled cylinders and interstage cooler lower operating and gas temperatures and increase seal life.
- Compact self-contained design.
- Cartridge type check valves.
- Replaceable gas cylinder liners.
- Low noise level.
- Noncontaminating with complete gas and drive cylinder isolation.
