HD-22S Single-stage Permanent Magnet Variable Frequency Screw Air Compressor (22 kW / 3.7 m³/min)

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.

The HD-55S is a mid-to-high-end single-stage permanent-magnet variable-frequency screw compressor from the Huada 2.0 series, delivering a power output of 55 kW, a flow rate of 10.5 m³/min, and a pressure rating of 0.8 MPa. Equipped with an IE5 permanent-magnet motor, a German-engineered main unit, and an intelligent IoT management system, this compressor is ideal for continuous gas supply applications in medium-to-large-scale factories, textile plants, material handling systems, and other similar scenarios.

The HD-75S is the flagship single-stage permanent-magnet variable-frequency screw compressor from the Huada INNOVATE 2.0 series, delivering a power output of 75 kW, a flow rate of 14 m³/min, and a pressure rating of 0.8 MPa. Equipped with an IE5 permanent-magnet motor, a German-engineered large-rotor main unit, and comprehensive IoT-based management capabilities, it provides efficient power supply for large-scale gas-utilization applications such as heavy-duty continuous production, wastewater treatment, and ship desulfurization.

The HB-30TD is the high-power flagship model in Huada's medium-pressure integrated machine series, delivering a main unit output of 22 kW with a large air volume of 2.2 m³/min and stable pressure of 1.6 MPa. It is specifically designed for high-power fiber laser cutting machines exceeding 3000 W and heavy-duty cutting production lines. Its integrated "key engineering" solution eliminates the costs associated with coordinating multiple equipment purchases, ensuring immediate readiness for use and reliable performance.

The SE-75 features a power output of 55 kW and a large displacement of 9.1 m³/min; equipped with an IE4 permanent magnet motor and a three-stage oil-gas separation system, it provides continuous and stable high-pressure air for heavy-duty manufacturing, large-scale auto parts production, and general industrial applications.

Our motors are manufactured by motor manufacturers according to high-level requirements to ensure that Huada screw air compressors are reliable and durable.At present,most manufacturers use IP23 protection levels,and our company all the use of IP54 above  the level of protection as the standard configuration of the product.

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 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.
