HDW4X1100-170D/S Four-pump oil-free silent air compressor

The Huada HDW550-10D is a 0.55 kW oil-free silent direct-drive air compressor powered by a 100% copper-wire motor. It requires no lubrication, operates at an ultra-low noise level of ≤48 dB, and delivers clean, dry, oil-free compressed air. With its compact lightweight design (only 19 kg) and 10 L tank, it is ideally suited for small-to-medium dental clinics, dental laboratories, precision electronics work, and small-scale model airbrushing where air purity is critical.

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.

Huada twin-screw vacuum pump drives the permanent magnet motor through a high-efficiency synchronous open-loop vector inverter, which drives the twin-screw main engine to rotate. Through the air intake valve, air filter and other components, it can extract air from the vacuum system according to the customer's gas demand, and can change the exhaust speed in real time to achieve a stable vacuum degree.

SE series permanent magnet variable frequency screw air compressor is a product with great design creativity. Compared with the same power machine, its volume is optimized by 40%, which refreshes the taste with compact design and inherits the ingenuity with quality technology. The materials are full of power, showing quality and exquisiteness everywhere, and every detail perfectly presents color, design and materials.

The HS1208 is a single-stage compression belt-driven air compressor with air-cooling system; it features a 1.1 kW power rating, a 40 L air storage tank, and an exhaust capacity of 0.12 m³/min. With its compact design and high mobility, this unit is an ideal air source for small auto repair shops, painting facilities, woodworking workshops, and home-based small-scale operations.

Huada two-stage dry oil-free screw air compressor uses dry oil-free compression to truly achieve 100% oil-free air.The rotor is made of high-quality corrosion-resistant stainless steel materials,high temperature resistance,corrosion resistance,oxidation resistance,and long life.
