Core Configuration:Superior Performance of a Two-Stage Handpiece

The AIRSTONE AS-420BD compressor features a two-stage handpiece. Its positive and negative rotors utilize a third-generation α-type asymmetric 5:6 tooth design. This precision structure provides the core support for the compressor‘s efficient operation. The rotor and bearing lifespans reach 30 million hours and 10 million hours, respectively, significantly reducing maintenance frequency and costs, ensuring long-term stable operation.

Basic Parameters and Operating Capabilities

This compressor, model AS-420BD, is air-cooled and operates in a wide ambient temperature range of -5°C to 50°C. With a discharge pressure of 0.8 MPa (a) and a capacity of 62 m2, it provides sufficient and stable compressed air for various industrial production scenarios. Capacity-controlled discharge, combined with a direct drive mode, further enhances operating efficiency.

Air Quality and Environmental Performance

The AS-420BD compressor delivers excellent compressed air quality, with outlet oil content below 3ppm and exhaust dust particles less than 1, meeting the stringent air quality requirements of industries such as food, pharmaceuticals, and electronics. Furthermore, the equipment boasts a noise level of only 86±2dB (A) and a unit vibration of ≤7mm/s, ensuring efficient operation while also prioritizing environmental protection.

Motor and Powertrain Configuration

The motor is 315kW-IP54, boasting a power output of 315kW and a speed of 2920rpm. It is compatible with a 380V/50Hz power supply and supports Y-△/permanent magnet variable speed starting. The motor‘s insulation class is F, its protection rating is IP55, and its service factor is 1.3, ensuring stable and reliable power output. It works perfectly with the two-stage handpiece for optimal performance.
