Product Overview

About Our Centrifugal Blowers

INDAIR's centrifugal blowers are designed and manufactured to deliver reliable, high-efficiency airflow in demanding industrial environments. Our centrifugal fans use the principle of centrifugal force to convert mechanical energy into pressure, making them ideal for applications requiring high pressure with moderate to high volumes.

Each blower is custom-engineered to meet your specific airflow (CFM or m³/hr), static pressure (mmwg), motor power, temperature, and material handling requirements. We manufacture in mild steel (MS), stainless steel (SS 304/316), galvanized iron (GI), and FRP for corrosive applications.

INDAIR centrifugal blowers are available in radial blade, backward-curved, and forward-curved impeller designs, each optimized for different operating characteristics. Our airfoil designs are based on established aerodynamic principles ensuring peak efficiency and minimal noise levels.
