Roots Blowers
Size & Capacity:
Bore Size : Diameter 40mm to 300 mm (1 1/2" ~ 12")
Flow Rate : 0.36m3/min ~ 160.00m3/min (12.5 ~ 5,700.00 CFM)
Static Pressure : Maximum achievable
Delivers completelv oil-free air.
Low oscillation and low noise by complete balancing.
Small variation in air volume against pressure variation.
Superior energy efficiency due to special lobe profile.
Simple structure keeps free from trouble.
High quality alloy steel gears are adopted. Precisely ground and hardened, which make smooth running and low noise. Long durability is guarantied.
4 pieces (in models bigger than 200, 6 pieces) of needle bearings are used to support rotots. Which can reduce friction noise, vibration, and increase service time.
Rotors are formed and profiled by CNC double column shaper, 4-axes machining in one process guaranty the rotors profile to be uniformed and in high precision.
Non-contact labyrinth seals are designed to reduce friction and heat generation, piston rings are set inside to make perfect seal for the air chamber.
