37kw 50hp Direct Drive Screw Air Compressor For Sale

Be different from belt drive system,which is due to the wear and slip of belt reduce efficiency and increase energy consumption,Huade direct drive system is to ensure high efficiency of energy transmission and constant flow output.

The HB-20TD is the flagship model in Huada's medium-pressure integrated system series, featuring a 15 kW permanent magnet frequency converter with a discharge capacity of 1.5 m³/min and stable pressure of 1.6 MPa, specifically designed for 1500–3000 W fiber laser cutting machines. Its integrated solution simplifies traditional multi-unit series configurations into a single unit, offering compact size, short piping requirements, and low pressure loss.

The two-stage compression energy-saving oil-injected screw compressor has a unique host design. It not only has all the advantages of a single-stage oil-injected screw air compressor, but also has a more reliable and energy-saving operation due to the low compression ratio of each stage, small force on the rotor and bearings, large rotor diameter and low speed.

The Huada HD0302(A) is a 2.2 kW (3 HP) dual-cylinder direct-connect air-cooled piston air compressor featuring a parallel twin-cylinder design where two 42 mm cylinders work in tandem to deliver a generous 0.20 m³/min displacement. Paired with a 30 L air receiver and 0.8 MPa (116 psi) working pressure, it can pressurize the tank from zero to rated pressure in approximately 90 seconds. The direct-coupled drive eliminates belt-slip losses, delivering superior mechanical efficiency over traditional belt-driven units. It is widely used in auto detailing and quick-repair shops for tire inflation, small bodywork pneumatic tool operation, finish carpentry nailer supply, wall spray painting, and other multi-tool simultaneous-operation scenarios.

The HDU45A is an enhanced oil-free twin-screw vacuum pump from the HDU series Type A; at the same 45 kW power rating, its maximum pumping rate is increased to 2,700 m³/h, with a maximum vacuum level of 300 mbar. It is specifically designed for applications requiring high pumping rates, such as photovoltaic laminating, CNC vacuum bonding, chemical distillation, and electronic component packaging.

Permanent magnet use high-srength NdFeB (neodymium iron boron) magnetic steel, high magnetic energyproduct and coercivity of NdFeB magnetic steel, make rare-earth permanent magnet motor have small size , lightweight , high ffient, good character etc, a series of advantages.

The LGGPM-350 features a robust 250 kW power output, delivering stable compressed air at 55 m³/min under 0.7 MPa pressure. Its independent air duct system scientifically separates the air intake for filtration, cooling, and overall operation, complemented by a biomimetic centrifugal fan to provide a cool and stable operating environment for high-power units.

As the flagship model of the new A-series air-cooled two-stage system, the LGGPM-480 delivers a top-tier power output of 355 kW and an ultra-high flow rate of 69.5 m³/min. Combining high-efficiency two-stage compression technology, intelligent IoT connectivity, dedicated air ducts, and a comprehensive service suite, it provides a stable, energy-efficient, and smart compressed air solution for large-scale production facilities.
