4 KW Oil Free Scroll Compressor

The SCR-10 is an industrial oil-free scroll air compressor with two compression modules. Its 2025 power configuration is 2 × 4 kW, with air delivery of 0.84 m³/min at 8 bar or 0.71 m³/min at 10 bar. Oil-free compression supports electronics, instrumentation and other processes sensitive to compressor oil contamination. Module staging, sequential starting and an operating-status display support daily use. The air-cooled cabinet measures 1100 × 800 × 980 mm.

The HDBS-40-150 is a 30 kW oil-free screw blower designed for industrial low-pressure air supply. Applications include wastewater aeration and pneumatic conveying. Its airflow range is 4.0–7.0 m³/min, with a pressure range of 80–150 kPa. Internal screw compression, an enclosed cabinet and forced-circulation lubrication and cooling are combined in one package. The operating point should be selected against the process airflow and backpressure requirements, with DN150 inlet and outlet flanges provided for pipeline connection.

The HDU45A is an enhanced oil-free twin-screw vacuum pump from the HDU series Type A; at the same 45 kW power rating, its maximum pumping rate is increased to 2,700 m³/h, with a maximum vacuum level of 300 mbar. It is specifically designed for applications requiring high pumping rates, such as photovoltaic laminating, CNC vacuum bonding, chemical distillation, and electronic component packaging.

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.

Short on floor space? The S-10 delivers 1.08 m³/min at 8 bar from a compact 7.5 kW unit, with an 880 × 660 mm footprint.

The HUADA SG-50 is a compact 37 kW single-stage permanent magnet VSD screw air compressor with a listed delivery of 6.1 m³/min at 0.7 MPa. Its 1000 × 1100 × 1200 mm cabinet, integrated direct-drive assembly and air cooling suit sites where equipment space needs careful planning.

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.

The HUADA LGGPM-30 is a 22 kW New A Series two-stage permanent magnet VSD screw air compressor with an air delivery of 4.1 m³/min at 0.8 MPa. A compact cabinet and centrifugal fan cooling make it a practical starting point for a dedicated production-area air supply.
