Huada HDV-2100 oil-lubricated twin-screw vacuum pump

Huada twin-screw vacuum pump drives the permanent magnet motor through a high-efficiency synchronous open-loop vector inverter, which drives the twin-screw main engine to rotate. Through the air intake valve, air filter and other components, it can extract air from the vacuum system according to the customer's gas demand, and can change the exhaust speed in real time to achieve a stable vacuum degree.

Need more air for your production equipment? The S-50 delivers 6.2 m³/min at 8 bar, with a 37 kW motor and fixed-speed direct drive.

The LGGPM-425 is a 315 kW ultra-high-power air-cooled unit that delivers 65 m³/min of compressed air at 0.7 MPa pressure. Featuring a modular design and high-strength sheet metal housing, it is specifically engineered for heavy industrial applications requiring continuous high-flow air supply, such as steel manufacturing, mining, and shipbuilding.

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 HD-37S utilizes Huada's 2.0 Series Single-Stage Permanent Magnet Variable Frequency Drive technology, delivering a discharge capacity of 6.4 m³/min at a power output of 37 kW and a pressure of 0.8 MPa. The German-engineered main unit is paired with an IE5 permanent magnet motor, providing stable and energy-efficient compressed air for mass production lines operating at medium-scale air consumption levels – particularly in machining, electronics, and plastics manufacturing applications.

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 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.

Need reliable compressed air without giving up valuable floor space? The compact M2.0-10 pairs a 7.5 kW permanent magnet motor with variable speed control and delivers a listed 1.4-1.1 m³/min across 0.7-1.0 MPa. With operating noise listed at 60 dB(A), it is a practical choice for smaller production areas.
