2.5HP Electric Direct Portable Air Compressor

The Huada HD0301 is a 1.8kW (3 HP) single-cylinder direct-connect air-cooled piston air compressor featuring a motor-to-pump direct coupling design that eliminates the traditional belt drive system. With ultra-compact dimensions of just 70×31×58 cm and a featherweight of only 32 kg—paired with a 35 L air receiver and 0.8 MPa working pressure—it stands out as one of the most compact and lightweight machines in its class. It is ideally suited for precision applications such as dental clinic air supply, laboratory instrumentation, small-scale electronics spraying, and model-making airbrushing where space efficiency and quiet operation matter.

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 Huada SG-20 is powered by a 15 kW single-stage permanent magnet variable-frequency drive, featuring a maximum discharge capacity of 2.4 m³/min (at 0.7 MPa), offering both stable output and a compact design; it is ideal for continuous gas application scenarios in small-to-medium manufacturing, architectural decoration, and automotive repair and bodywork.

Two stage compression screw air compressor reduces the compression ratio per level,reducing internal leakage and increase the volumetric efficiency,reduces the bearing load,improve the working life of the host.Two stage compression instead of single stage compression,nearly a 15% increase in displacement,can realize a 15% more energy saving effect.

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 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 SC energy-saving series screw machine achieves first level energy efficiency, with inherent reliability, energy saving, and quietness in operation. The overall design is simple and can adapt to various working environments, meeting the gas needs of various industries.

The oil free scroll air compressor produced by our company has obtained the ISO 8573-1 CLASS-0 certificate from the well-known TUV certification body to ensure the safety of user production,reduce maintenance costs,and provide peace of mind.
