Multi stage blowers

Multi-stage blowers

  • Our upgraded series: 4RB Side Channel Blowers, or three stage Side Channel Blowers, as known as multi-stage vacuum pumps or vacuum compressors or ring blowers, they generate a great differential pressure up to 1,00Kpa. Hence, it’s far higher than any other gas ring compressor. Till now, those pumps which can reach the pressure of our side channel blowers are bigger in structure, larger noise, and easy to abrasion. 4RB Side Channel Blowers can still operate under more harsh working conditions, and also can operate continuously for 20,000 hours without downtime maintenance. Therefore, their excellent safety and reliability have been proven, even they are under harshest working conditions.

  • 3RB series three stage side channel blowers is a new series blower which can create high pressure and high vacuum and high airflow. It can replace equivalent power of Roots blower, but side channel blowers have more advantages than Roots blower. The advantages contain:First, the weight is much lighter and the volume is even compacter;Second, the lifetime is longer;Third, it’s low noise and oil free; The last, it’s free maintenance.

Remarks:1. Measured the surface of acoustic intensity according to the distance of EN216801 at 1 meter. At this time, it clamps the Side Channel Blower to a moderate inlet positive pressure; Connecting the hose to the exhaust side; And the suction side is not equipped with a negative pressure relief 2. To order information of the selection, please refer to the accessory set. Besides, the ultimate positive pressure of the valve basing on an ambient temperature of 25 °C; And is related to the cooling medium.3. Regarding the 2RB1 943 model, there is only a vertical installation.4. Tolerance: The motor complies with DIN EN 60 034/DIN IEC 34-1. It has an insulation class F. 

Three phase:Fixed voltage +10%Wide pressure +5%US Standard (UL) and Canadian Standard(CSA) are 10%/+6% respectively Simplex: Fixed voltage +5%Under continuous working conditions. If only using 90% of the maximum working positive pressure, then the voltage for the tolerance can increase to ±10US Standard (UL)and Canadian Standard (CSA) are 10% + 6% respectively Frequency ±2%.
