Can AC Centrifugal Fans Handle Corrosive or Hazardous Environments?

Can AC Centrifugal Fans Handle Corrosive or Hazardous Environments?

Yes. AC centrifugal fans can be specifically engineered to withstand corrosive gases, chemical exposure, high humidity, and explosive atmospheres. These specialized designs ensure safe and reliable performance in the most demanding industrial environments—such as chemical plants, oil refineries, food and pharmaceutical production facilities, wastewater treatment plants, and more.

Here’s how our engineered fan solutions meet these extreme conditions:

✔️ Corrosion-Resistant Construction Materials

Stainless Steel (304/316): Offers excellent resistance to acidic vapors, saline air, and oxidizing agents—ideal for food processing, marine, or pharmaceutical applications.
FRP (Fiberglass-Reinforced Plastic): Highly resistant to corrosive chemicals such as chlorine, sulfuric acid, and caustics; perfect for fume extraction and scrubber exhaust.
Coated Carbon Steel: Powder coating, epoxy paints, or chemical-resistant finishes provide a cost-effective barrier against corrosion in general-purpose industrial use.

Application Example: Exhaust systems for pickling lines, chemical storage ventilation, or coastal installations.

✔️ Explosion-Proof (XP) Motors for Hazardous Locations

Fans used in Classified Areas (per NEC, ATEX, or IECEx standards) must be equipped withexplosion-proof motors designed to contain or prevent ignition of flammable gases, vapors, or dust.
Available classifications include:
- NEC Class I, Div 1 or Div 2 (gas/vapor)
- Class II, Div 1 or Div 2 (combustible dust)
- Zone 1 and Zone 2 configurations

Required in oil and gas facilities, paint booths, solvent recovery systems, and chemical reactors.

✔️ Sealed Bearings and Ingress Protection

Fans operating in corrosive or humid environments may requiresealed or shielded bearings with IP-rated enclosures (e.g.,IP55/IP66) to prevent:
- Moisture ingress
- Chemical vapor intrusion
- Dust contamination
Optional food-grade bearing grease available for sanitary environments.

Result: Extended service life and reduced failure rates in aggressive operating conditions.

✔️ Custom Protective Coatings

Coating options include:
- Epoxy and phenolic coatings for acidic gases
- Teflon or fluoropolymer linings for chemically active exhaust
- Zinc-rich primers and marine-grade topcoats for outdoor or coastal durability

Critical in air scrubber exhausts, fume hoods, and air pollution control systems.

✔️ UL / CSA / CE Safety Certifications

All hazardous-duty fans and motors are available with:
- UL Listed / CSA Certified for North American compliance
- ATEX / IECEx for global applications
- Compliance with NFPA 91 (Standard for Exhaust Systems)

Ensures your fan system meets safety, regulatory, and insurance requirements.

✔️ OSHA-Compliant Safety Guards

Protective inlet and outlet guards are standard or optional based on application, designed to:
- Prevent personnel contact with rotating components
- Withstand corrosive environments usingSS or coated guard materials

Required for worker safety and OSHA compliance in open-access areas.
