37kw 50hp Direct Drive Screw Air Compressor For Sale

Be different from belt drive system,which is due to the wear and slip of belt reduce efficiency and increase energy consumption,Huade direct drive system is to ensure high efficiency of energy transmission and constant flow output.

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 Huada HDW750-24D is a 0.75 kW (1 HP) oil-free silent direct-drive air compressor purpose-built for fine-detail applications such as art airbrushing, model making, and electronic coating that require steady continuous air supply. Featuring a 100% copper-wire motor, electromagnetic unloading valve, and high-efficiency aluminum radiator, it operates at ≤50 dB with clean oil-free output. The 24 L tank ensures stable pressure delivery—an ideal air supply unit for studios and maker spaces.

The HDW1100-24D is a compact oil-free silent piston air compressor featuring a 1.1 kW all-copper motor, a 24L air storage tank, and an exhaust capacity of 150 L/min; it operates at a noise level of ≤55 dB, delivers clean, oil-free output airflow, and is particularly well-suited for applications such as dental clinics, small laboratories, electronic repair shops, and home DIY projects where high requirements are placed on air cleanliness and quiet operation.

Permanent magnet use high-srength NdFeB (neodymium iron boron) magnetic steel, high magnetic energyproduct and coercivity of NdFeB magnetic steel, make rare-earth permanent magnet motor have small size , lightweight , high ffient, good character etc, a series of advantages.

The TVD+ series 15 kW permanent-magnet two-stage variable-frequency screw compressor features a dual-screw unit paired with an IE5 motor, delivering overall efficiency 20% higher than that of single-stage models and providing stable, clean, energy-efficient compressed air for small to medium-sized production lines.

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 SED+ series 75 kW gear-driven, two-stage variable-frequency screw air compressor features a 35% comprehensive energy efficiency rate, robust IP55 protection, and AirLink IoT-based intelligent management, making it an efficient, energy-saving air source solution for heavy manufacturing, energy, and textile industries.
