Water Lubrication Twin Screw Air Compressor

Huada HDW series dry oil-free screw compressor adopts Germany technology oil-free air end, which is a highly environmentally friendly and energy-efficient oil-free screw machine that has passed the Germany TUV CLASS 0 oil-free certification, and the compressed air quality produced exceeds the original grade stan- dard of"ISO8573-1" and reaches the more stringent air purity level "lSO8573-1 Class0".To meet the customer' requirements for high quality of compressed air and ensure the quality and safety of air purity.

The refrigeration dryer is composed of drying chamber,vacuum system,heat source,and low temperature condenser.In stric accordance with iso9001,gb150,iso7183 refrigerant air dryer standard,qs,pressure vessel inspection specifications for design and manufacture of production and testing,to ensure product safety and reliable operation.

The HDW1100-24D is a compact oil-free silent piston air compressor featuring a 1.1 kW all-copper motor, a 24L air storage tank, and an exhaust capacity of 150 L/min; it operates at a noise level of ≤55 dB, delivers clean, oil-free output airflow, and is particularly well-suited for applications such as dental clinics, small laboratories, electronic repair shops, and home DIY projects where high requirements are placed on air cleanliness and quiet operation.

The Yiluma SV-30+ features a 22 kW permanent magnet variable-frequency compressor with a maximum discharge capacity of 3.45 m³/min (0.7 MPa). Through seamless integration of intelligent frequency conversion technology and a dedicated controller, it delivers stable, clean, and easy-to-manage compressed air for medium-sized factories.

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.

The Huada HDW750-24D is a 0.75 kW (1 HP) oil-free silent direct-drive air compressor purpose-built for fine-detail applications such as art airbrushing, model making, and electronic coating that require steady continuous air supply. Featuring a 100% copper-wire motor, electromagnetic unloading valve, and high-efficiency aluminum radiator, it operates at ≤50 dB with clean oil-free output. The 24 L tank ensures stable pressure delivery—an ideal air supply unit for studios and maker spaces.

The 37kw permanent magenta variable  frequency compressor is high-efficiency save power machine.It is designed in the FEM strength analysis to ensure the stability and reliablility of each part,and to realize long term operation with no faults,low noise and long life.

As one of the flagship models in the new A series, the LGGPM-300 delivers a maximum exhaust volume of 48.6 m³/min with a driving power of 220 kW. Its innovative dual-stage compressor features a rotor design combining a large rotor with low-speed operation, achieving lower compression ratios and reduced bearing loads while delivering high energy efficiency and extended service life.
