The FJRTB series three-lobe roots blower is a type of displacement blowers. The pressure can be adjusted within the range permitted according to the user's specific needs. Inside the blower body, there are two impellers that rotate in opposite directions. To enable the impellers to rotate smoothly, there exist small gaps between the impellers and the casing, as well as between the two impellers. When the impeller rotates through the suction inlet, it can gather an amount of air between the casing and impeller, then the impeller continue to, and the air will be pressured, the pressure in the casing will rise, finally the air has been sent to the outlet.
*Wide range of capacity and pressure.
Calibre: 32mm-400mm(1.25"-16")
Capacity: 0.38-283m³/min(13-9985CFM)
Pressure:
The pressure of one-stage GRB type up to 8000mmAq(0.8kgf/cm²)
*Deliver completely oil-free air.
*Low oscillation and low noise by dynamic balance which revised by computer.
*Smaller change in capacity against change in pressure.
*High efficiency due to special impeller design, higher air-delivery lower consumption.
*Durable structure,less potential manufacturing failure.
*High grade quality gears ensure high precision,long lifespan and low noise.
*Our impeller use the most advanced technique,one time for all working process of the six-shaft method,to enhance the precision.
