How Does a Flameproof Exhaust Fan Work?

• Flameproof Motor: Enclosed motor prevents sparks from igniting external gases.
• Non-sparking Impeller: Aluminum / plastic / FRP blades to avoid friction sparks.
• Heavy-duty Casing: Cast aluminum, steel, or FRP construction.
• Sealed Cable Glands: Prevent gas entry into electrical parts.
• Low surface temperature: Prevents auto-ignition of gases.

Working Principle:

• Fan extracts contaminated or explosive air.
• Fresh air enters the space.
• Hazardous gases are diluted below explosive limits.
• Any internal fault does not ignite external atmosphere

Where Is It Used? (Applications)

Industrial & Hazardous Locations: Chemical plants. Oil & gas refineries. Petroleum storage areas. Paint booths. Battery charging rooms. Pharmaceutical plants. Solvent handling areas. LPG / CNG stations. Coal mines. Sugar & flour mills (combustible dust)

Advantages

• Prevents explosions & fire accidents
• Safe continuous operation
• Long service life
• Complies with industrial safety norms
• Reduces gas concentration

Product Details:

“SAIEX” flameproof wall-mounting fan is a special industrial ventilation fan designed to operate safely in hazardous environments where flammable gases, vapors, or dust may be present. It is built so that no spark, heat, or electrical fault can ignite an explosive atmosphere.

A flameproof wall-mounting fan is:

• A ventilation or exhaust fan
• Mounted on a wall
• Certified explosion-proof / flameproof
• Designed according to ATEX / IECEx / IS standards
• Prevents ignition even if an internal spark or short circuit occurs

The motor and electrical parts are enclosed in a heavy, sealed housing that can:

• Withstand internal explosions
• Prevent flames from escaping to the outside atmosphere

Various Names Used for Flameproof Wall Fans: Flameproof Wall Fan, Explosion-Proof Wall Mount Fan, Hazardous Area Wall Fan, ATEX Certified Wall Fan, IECEx Wall-Mounted Ventilation Fan, Spark-Proof Wall, Exhaust Fan, Anti-Explosion Wall Fan, Industrial Flameproof Ventilation Fan.

How Does a Flameproof Wall Fan Work?

Key Design Features:

• Flameproof motor enclosure
• Non-sparking aluminum or anti-static blades
• Heavy-duty cast iron or aluminum body
• Sealed cable glands
• Thermal protection
• Earthing (grounding) connection

Working Principle:

1. Fan draws in contaminated air

FLAMEPROOF PEDESTAL FAN

“SAIEX” A flameproof pedestal fan is a special-purpose industrial fan designed to operate safely in hazardous areas where flammable gases, vapors, or dust may be present.

A flameproof pedestal fan is a portable, floor-mounted fan with a flameproof (explosion-proof) motor and electrical components. It is built so that: Any spark or internal explosion inside the motor cannot ignite the surrounding atmosphere. The enclosure withstands internal explosions and prevents flame propagation outside.
