Kay vs Swam vs Everest

Brand	Types	Flow / pressure	Notes
Kay	Twin lobe and tri lobe Roots	50–80,000 m³/hr, up to 1 kg/cm²	Acoustic hood option for noise-sensitive sites
Swam	Roots	Up to 80,000 m³/hr, up to 1.10 kg/cm² single stage	Continuous duty; works as blower, compressor or exhauster
Everest	Roots and centrifugal	Roots up to 1 kg/cm²	Centrifugal option for large, steady flow

Figures are typical ranges. Exact model, motor rating and delivery time are confirmed once we have your flow and pressure requirement.

Which Blower Technology Do You Need?

Twin lobe Roots: the standard positive displacement design for small to mid-size aeration and conveying.
Tri lobe Roots: the same principle with less pressure pulsation, so it is quieter and smoother. Read the twin vs tri lobe guide.
Centrifugal: suited to large, steady flows at moderate pressure.

How to Choose the Right Blower

Selection comes down to three things: required airflow, discharge pressure and duty cycle. Our air blower sizing guide walks through the method with a worked example, or use the free air blower sizing calculator for an instant estimate.

Frequently Asked Questions — Air Blowers

Which air blower brands does QuaSys supply?+

QuaSys Inc. supplies Kay, Swam and Everest air blowers across India for aeration, conveying and process applications.

How do I select the right air blower for STP aeration?+

Key parameters are aeration tank volume, BOD load, oxygen transfer requirement, diffuser submergence depth and total system pressure drop. Share your tank drawing and treatment capacity and our team will recommend a model.

What is the difference between twin lobe and tri lobe blowers?+

Both are Roots positive displacement blowers. A tri lobe adds a third lobe to each rotor, which reduces pressure pulsation, noise and vibration compared with a twin lobe of the same duty.

Does QuaSys provide AMC and spare parts for air blowers?+

Yes. QuaSys Inc. offers Annual Maintenance Contracts and spare parts support for the blowers it supplies, with dispatch across India.
