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.

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.

The HDBS-40-150 is a 30 kW oil-free screw blower designed for industrial low-pressure air supply. Applications include wastewater aeration and pneumatic conveying. Its airflow range is 4.0–7.0 m³/min, with a pressure range of 80–150 kPa. Internal screw compression, an enclosed cabinet and forced-circulation lubrication and cooling are combined in one package. The operating point should be selected against the process airflow and backpressure requirements, with DN150 inlet and outlet flanges provided for pipeline connection.

The SED+ series 160 kW gear-driven dual-stage variable-frequency screw air compressor is a flagship product, combining 35% energy efficiency, variable-frequency vector control, dual-frequency noise reduction technology, and AirLink IoT-based comprehensive management—making it the premier air source solution for mining and heavy industry.

The S-20 brings 15 kW of fixed-speed screw compression to your workshop, delivering 2.3 m³/min at 8 bar. Its direct drive and cooling airflow design help keep everyday operation practical.

The LGPM-30TD is a permanent magnet VSD all-in-one screw air compressor for laser cutting air supply, with a 22 kW compressor motor. Its compressor air delivery is 2.2 m³/min at 16 bar. The package integrates a screw compressor, refrigerated dryer, precision filters and air receiver. The HD-30AC dryer has a treatment capacity of 3.0 m³/min. This integrated arrangement reduces inter-component piping work and provides drying and filtration in a 1850 × 1320 × 1860 mm package.

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.
