HD-37S Single-stage Permanent Magnet Variable Frequency Screw Air Compressor (37 kW / 6.4 m³/min)

HD-37S Single-stage Permanent Magnet Variable Frequency Screw Air Compressor (37 kW / 6.4 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.

1. 37 kW – High power output; 6.4 m³/min – Stable gas supply: Rated discharge capacity of 6.4 m³/min at 0.8 MPa – Ideal for small to medium-sized factories with multiple equipment operating simultaneously, ensuring minimal pressure fluctuations and continuous gas supply.

2. IE5 Permanent Magnet Variable Frequency Drive – On-Demand Output: The variable frequency system adjusts rotational speed in real time based on pipeline network pressure, featuring low unloading losses and superior overall energy efficiency compared to conventional industrial-frequency screw compressors.

3. German-engineered main unit + high-efficiency radiator: A large rotor, low-speed main unit paired with a large-area plate-type radiator ensures stable exhaust temperatures (≤ ambient temperature + 15°C), guaranteeing reliable operation in high-temperature workshops.

4. 99.99% air filtration – ensures a cleaner air supply: 3 μm high-precision intake filtration combined with multi-stage oil and gas separation achieves a filtration efficiency of 99.99%, effectively protecting downstream air-using equipment and processes.

5. Five-year warranty on the entire device – worry-free after-sales service: A five-year warranty commitment for core components, complemented by a 24/7 nationwide service hotline and a professional after-sales team, helping to mitigate operational and maintenance risks throughout the user's entire lifecycle.
