portable screw air compressor for automotive 4S dealership

This portable screw air compressor combines frequency control, screw compression technology and pure copper brushless motor to ensure high energy efficiency and stable air supply. It is suitable for many industries such as construction spraying, automobile maintenance, small factories and so on.

Description

Portable screw air compressor is an efficient and stable air source equipment, which adopts advanced screw compression technology and can continuously provide stable high pressure air. The equipment is equipped with frequency conversion drive system and pure copper brushless motor to ensure smooth operation, low energy consumption and long service life. It is suitable for exterior painting, automobile maintenance, 4S stores, small factories and other scenarios that require efficient compressed air.

Features of Portable Screw Air Compressor

  1. High efficiency and energy saving: Frequency control technology dynamically adjusts the motor speed according to actual air demand, avoiding unnecessary energy loss. Compared to traditional fixed-frequency air compressors, it can save 20%-50% of electrical energy. 380V industrial power supply ensures stable and efficient long-time operation.
  2. Strong power: Pure copper brushless motor reduces energy loss, is maintenance-free, and highly durable. It can drive 3-4 large-diameter spray guns simultaneously to meet the needs of large-area spraying operations.
  3. High air quality, stable air supply: Advanced screw compression technology provides more stable airflow compared to piston air compressors, avoiding pulse airflow that affects spraying uniformity. The 120L large-capacity air tank ensures continuous and stable air supply, reducing pressure fluctuations and improving spraying quality.
  4. Intelligent control, easy to operate: Variable frequency drive with intelligent control panel allows users to adjust pressure and flow rate at any time, achieving precise air output control. Low noise design is suitable for indoor or noise-sensitive areas.
  5. Strong durability, adapts to harsh environments: The body is made of corrosion-resistant materials, suitable for high temperature, high humidity, or dusty construction sites. Low maintenance costs and stable long-term performance.

Working Principle of Portable Screw Air Compressor

Adopting twin-screw compression technology, a sealed chamber is formed by a pair of mutually meshing screws rotating inside the casing, and the air is gradually compressed in the chamber and discharged in the form of high pressure.
1. Air intake: External air enters the compression chamber through the air inlet.
2. Compression process: The sealing chamber produced by the screw rotation is gradually narrowed, increasing air pressure.
3. Cooling and exhausting: High-pressure air is cooled by the cooling system and then enters the air storage tank to be output at a stable flow rate.
4. Frequency conversion adjustment: The frequency converter automatically adjusts the screw’s rotational speed according to air demand, enabling energy-saving operation and stable air pressure.
Compared with traditional piston air compressors, screw air compressors offer higher efficiency, more stable air supply, and eliminate vibration and noise caused by reciprocating pistons, making them ideal for continuous air supply scenarios.

Application Areas of Portable Screw Air Compressor

  1. Construction and exterior wall spraying: Suitable for large-area exterior wall spraying, such as real stone paint and emulsion paint projects that require long, continuous operation. Stable air supply ensures more uniform spraying, reducing color variation and uneven coating.
  2. Automobile maintenance and 4S stores: Ideal for auto painting, sheet metal repair, tire inflation, and pneumatic tool operation. Low noise design improves comfort in workshop environments.
  3. Small factories and production lines: Can drive pneumatic tools, equipment, packaging machinery, and more to boost production efficiency. Intelligent frequency conversion control adapts to different production needs.
  4. Furniture manufacturing and woodworking industry: Suitable for painting, wood carving, pneumatic nail guns, and other woodworking processes. Stable operation prevents moisture in compressed air from affecting spray paint quality.
  5. Other industries: Also suitable for food processing, electronics manufacturing, and other sectors requiring high air source quality. Durable, easy to maintain, and capable of stable long-term operation.
