Ring Blowers
Ring blowers Air blowers are industrial type of blower which is used to provide continuous air supply of low or medium pressure without oil. The applications of them are very common in aquaculture, bio floc system, wastewater treatment and industrial processes.
How a Ring Blower Works?
The impeller is a high-speed rotating item contained within a ring-like housing.
Centrifugal force accelerates the movement of air and compresses it along the ring.
Provides low noise and vibration air delivery.
Key Features
Oil-free oil (fish-safe and bio floc-safe).
Continuous duty (24×7 operation)
Low maintenance
Compact & energy efficient
Silent as compared to roots blowers.
Common Uses
Bio floc tanks (aeration using air diffusers / air stones) fish farming.
Wastewater & ETP/STP aeration
Pneumatic conveying
Burners & furnaces
Printing machines and packaging machines.

Ring Blower vs Air Pump
Increased airflow Decreased airflow.
Farther than great tanks small tanks.
Light duty Continuous industrial use.
Longer life shorter life
Suitable for Bio floc?
Yes. Ring blowers would be among the optimal selection of bio floc fish farming where adequate air diffusers are employed.
