2.5HP Electric Direct Portable Air Compressor

The Huada HD0301 is a 1.8kW (3 HP) single-cylinder direct-connect air-cooled piston air compressor featuring a motor-to-pump direct coupling design that eliminates the traditional belt drive system. With ultra-compact dimensions of just 70×31×58 cm and a featherweight of only 32 kg—paired with a 35 L air receiver and 0.8 MPa working pressure—it stands out as one of the most compact and lightweight machines in its class. It is ideally suited for precision applications such as dental clinic air supply, laboratory instrumentation, small-scale electronics spraying, and model-making airbrushing where space efficiency and quiet operation matter.

The Huada HD0302(A) is a 2.2 kW (3 HP) dual-cylinder direct-connect air-cooled piston air compressor featuring a parallel twin-cylinder design where two 42 mm cylinders work in tandem to deliver a generous 0.20 m³/min displacement. Paired with a 30 L air receiver and 0.8 MPa (116 psi) working pressure, it can pressurize the tank from zero to rated pressure in approximately 90 seconds. The direct-coupled drive eliminates belt-slip losses, delivering superior mechanical efficiency over traditional belt-driven units. It is widely used in auto detailing and quick-repair shops for tire inflation, small bodywork pneumatic tool operation, finish carpentry nailer supply, wall spray painting, and other multi-tool simultaneous-operation scenarios.

The refrigeration dryer is composed of drying chamber,vacuum system,heat source,and low temperature condenser.In stric accordance with iso9001,gb150,iso7183 refrigerant air dryer standard,qs,pressure vessel inspection specifications for design and manufacture of production and testing,to ensure product safety and reliable operation.

45kw double stage compression structure, more energy saving. Compression and high efficiency screw machine is a low pressure ratio, a greater drgree of lower volume leakage to improve energy efficiency. Lower than ordinary screw speed, and the use of of multiple damping springs, so that the unit has a higher stability.

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 LGPM-20 uses an IE4 permanent magnet motor with IP54 totally-enclosed protection, delivering 35–45% energy savings at 15kW for lines demanding safety and efficiency.

The SC energy-saving series screw machine achieves first level energy efficiency, with inherent reliability, energy saving, and quietness in operation. The overall design is simple and can adapt to various working environments, meeting the gas needs of various industries.

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.
