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 TVD+ series 5.5 kW permanent magnet two-stage variable-frequency screw compressor combines a two-stage compression unit with an IE5-class permanent magnet variable-frequency motor, delivering overall efficiency 15–20% higher than China's National Grade 1 energy standards—a cost-effective energy-saving solution specifically designed for small workshops.
The TVD+ series 55 kW permanent-magnet two-stage variable-frequency screw air compressor features top-tier energy efficiency, ultra-low noise levels, and intelligent cloud-based management as its flagship advantages, making it the premier air supply solution for large-scale manufacturing, energy, textile, and chemical industries.
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.
The LGGPM-380 delivers an ultra-high exhaust capacity of 62 m³/min at 280 kW power, specifically designed for heavy-duty industries such as energy, chemical, and metallurgy. Its dual-stage compression unit works in synergy with a high-efficiency permanent magnet motor, while the IP55 protection rating ensures reliable long-term operation in dusty industrial environments.
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.
The SV-100 is a 75 kW permanent magnet variable-frequency screw air compressor from the YILUMA series, specifically designed for medium-capacity production lines. Combining a stable air output of 12.7 m³/min at 0.8 MPa with flexible variable-frequency control, this unit provides a first-class energy-efficient air supply for continuous operation scenarios such as automotive parts manufacturing, electronic assembly, textiles, and printing.
The SV-150 is a 110 kW permanent magnet variable-frequency screw air compressor from the YILUMA series, designed for heavy-duty industrial applications. Combining an exceptionally large discharge capacity of 20.0 m³/min and 0.8 MPa with a heavy-duty motor, this unit meets the stable air supply requirements of continuous high-load production lines in sectors such as mining, metallurgy, large-scale automotive manufacturing, and chemical fiber production.
The SE-30 delivers a power output of 22 kW and a stable air flow rate of 3.2 m³/min; its volume is 40% smaller than that of comparable models with the same power rating, making it an ideal cost-effective air supply solution for small to medium-sized workshops, automotive maintenance facilities, and electronic production lines.
The SE-50 is equipped with a 37 kW permanent magnet variable-frequency drive system, delivering a stable output of 5.0 m³/min at 0.8 MPa; it balances energy efficiency with reliability, making it suitable for medium-duty gas application scenarios such as mechanical manufacturing, textile processing, and food processing.
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.
