Parts of a Centrifugal Fan: Components and Their Functions
The main parts of a centrifugal fan are the impeller, volute casing, inlet cone, discharge outlet, shaft, bearings, and the motor with its drive. Air enters the impeller along the shaft. The spinning blades throw it outward, and the…

What Is an Industrial Blower and How Does It Work
An industrial blower is a machine that moves air or gas at a higher pressure than a standard fan. A motor-driven impeller or rotor draws gas in, adds energy to it, and discharges it against system resistance. Under the ASME PTC 11…

Centrifugal Blower Material Guide: MS vs SS 304/316 vs FRP for Corrosive Air
MS (with coating or lining) suits dry, dusty or mildly humid air where no acid is present. SS 304 suits humid, food-grade and mildly corrosive air without chlorides. SS 316 / 316L suits chloride-bearing, pharmaceutical and solvent-laden…

Plug Fan vs Centrifugal Fan
A plug fan (also called a plenum fan) is a centrifugal fan with a backward-curved impeller and no scroll casing, discharging air into a plenum or AHU. A traditional centrifugal fan uses a scroll housing to direct air toward a defined…

High Temperature Industrial Fans: Material Selection from 200°C to 600°C
Mild steel (IS 2062) covers fan duties to about 425°C, but enters the creep range above roughly 370°C – continuous service there needs SS 304H or a chrome-moly grade. From 425°C to 550°C, stabilised SS 321 replaces plain SS 304, which…

What Is an FD Fan
In any boiler or furnace, fuel is only half the story – combustion also needs a steady, controlled supply of air. That air is delivered by a forced draft fan. This guide explains what a forced draft fan is, how it works, its main types…
