Luoyou 55KW/75HP VSD Screw Air Compressor 8/10/13 Bar

The LY-75CV is a single-stage, oil-injected screw air compressor from Luoyou, rated at 55 kW (75 hp) and built on a variable speed drive. It produces 10.05 m³/min at 8 bar, 7.8 m³/min at 10 bar, and 7.3 m³/min at 13 bar. The machine is supplied directly from the Luoyou factory in China, giving business buyers one point of contact for the unit and its technical documentation. It targets plant air, pneumatic tooling and general production supply, where steady pressure and lower part-load consumption are priorities.

Performance of the VSD Screw Air Compressor

The LY-75CV covers three working pressures. At 8 bar (0.8 MPa, 8 kg) the delivered flow is 10.05 m³/min; at 10 bar (1.0 MPa, 10 kg) it is 7.8 m³/min; at 13 bar (1.3 MPa, 13 kg) it is 7.3 m³/min. Output falls as pressure rises, which is expected on a single-stage screw element and gives plant engineers a clear choice: run the system at the lowest pressure the production process accepts, and the machine moves more air per kilowatt. Because the drive is variable-speed, motor speed follows actual air demand instead of running at a fixed speed. When consumption drops, the compressor slows down, so energy input moves with the load — a point that matters to industrial clients whose plant air demand varies across shifts.

Construction of the Single-Stage Screw Air Compressor

A single-stage design keeps the machine compact and the component count low. In an oil-injected screw compressor, oil seals, cools and lubricates the compression chamber, and the oil is separated from the air before it reaches the outlet. The LY-75CV is listed in Luoyou's range as a low-noise industrial screw air compressor. The factory package includes intake filtration, an oil separation loop and the cooling system, and the unit leaves the factory fully assembled.

Factory Supply of the LY-75CV Screw Air Compressor

The LY-75CV is offered factory-direct by Luoyou Compressor in China. Buying from the manufacturer means the export team handles the order, and technical documentation is available from Luoyou's download section. This setup suits commercial users who prefer to work with the source of the machine rather than through an intermediary. For enterprise customers managing several sites, dealing directly with the factory also keeps model, part and documentation queries under one roof.

Energy Use of the Screw Air Compressor

A fixed-speed screw compressor runs at full speed whenever it is switched on, even when little air is drawn. The VSD on the LY-75CV changes that: the drive adjusts motor speed to match demand, so during light-load periods the compressor turns slowly and draws less power. Plants with shift-based or batch production see the benefit directly on the electricity meter. Luoyou lists the machine in its range as an energy-saving industrial screw air compressor, and the factory can advise on expected power draw for a given duty cycle on request.

FAQ

What output does the LY-75CV deliver at each pressure?

At 8 bar the unit delivers 10.05 m³/min, at 10 bar 7.8 m³/min, and at 13 bar 7.3 m³/min.

What do 8 kg, 10 kg and 13 kg pressure ratings mean?

They are the metric equivalents of the bar ratings — 8 kg corresponds to 0.8 MPa, 10 kg to 1.0 MPa, and 13 kg to 1.3 MPa.

Is the LY-75CV a single-stage or two-stage compressor?

It is a single-stage, oil-injected screw air compressor with a variable speed drive.

Why does the LY-75CV use a variable speed drive?

The VSD adjusts motor speed to air demand, so the compressor does not run unloaded when consumption is low.

Where is the LY-75CV manufactured?

The LY-75CV is made in China at the Luoyou factory, which also supplies the unit factory-direct.

What is the difference between bar and kg/cm² ratings?

Both notations express the same pressure — 1 bar equals 1 kg/cm², so 8 kg, 10 kg and 13 kg match 0.8 MPa, 1.0 MPa and 1.3 MPa.
