Flameproof Fans / Explosion Proof Industrial Ventilation Fans Manufacturer India
Trimiti Electricals supplies flameproof and explosion proof industrial fans for safe ventilation in hazardous classified areas. Also known as Ex-proof exhaust fans, Zone 1 ventilation fans, or hazardous area air circulation fans, our products are engineered to prevent sparking and heat generation that could ignite surrounding explosive atmospheres. Whether the application is exhaust ventilation, forced air circulation, or pedestal-mounted cooling for personnel and equipment, we have certified solutions for your requirement.
Our flameproof fan range is built with non-sparking impeller materials, certified motors wound for flameproof operation, and robust housings designed to withstand the harsh industrial environment. Available in exhaust, wall-mount, and pedestal configurations, our fans are used wherever flammable solvents, gases, or vapours make standard fans a safety risk.
Available Product Variants
i) Flameproof Exhaust Fans — Sizes from 12 to 24 inches (blade diameter)
ii) Flameproof Wall Mount Fans
iii) Flameproof Pedestal Fans
Industries & Applications
Our explosion proof fans are installed in solvent storage rooms, paint spray booths, chemical mixing areas, pharmaceutical solvent dispensing rooms, battery charging rooms (hydrogen hazard), LPG and CNG facilities, fuel tank farms, printing plants with flammable ink storage, and offshore ventilation systems. Any area classified Zone 1 or Zone 2 where electrical equipment requires Ex certification needs certified flameproof fans for ventilation duty.

Frequently Asked Questions
Q1. Why do I need a flameproof fan in a hazardous area?
Standard industrial fans use conventional motors and impellers that can generate sparks from electrical or mechanical contact. In areas where flammable gases or solvent vapours are present, a single spark can cause fire or explosion. Flameproof fans use Ex-certified motors and non-sparking blades to eliminate this risk.
Q2. What is the difference between an exhaust fan and a wall mount flameproof fan?
An exhaust fan is mounted in a wall or ceiling opening and draws air from the room, discharging it outside — typically used for extraction of solvent fumes or general air changes. A wall mount fan recirculates internal air for localised cooling. A pedestal fan is free-standing and mobile, used where fixed installation is impractical.
Q3. What sizes of flameproof exhaust fans do you offer?
We supply flameproof exhaust fans from 12-inch to 32-inch blade diameter, covering ventilation requirements from small utility rooms to large process areas.
Q4. Can flameproof pedestal fans be used in battery charging rooms?
Yes. Battery charging rooms present a hydrogen (IIC gas group) hazard from off-gassing during charging cycles. Our IIC-rated flameproof fans are suitable for this application.
Q5. What is the motor rating and certification for your flameproof fans?
Our fans use flameproof motors certified to IS/IEC 60079-1 (Ex d) standards. Motor ratings vary by fan size and model. Please contact us with your airflow requirement (CFM/CMH), static pressure, and area classification for motor selection and certification details.
