Corrosion-Resistant Bifurcated Fans for Hazardous Environments

Isolated Motor Protection

Our bifurcated fans feature a unique split-housing design that completely isolates the drive motor from the contaminated airstream. As a leading bifurcated fan manufacturer, we engineer this critical separation to protect electrical components from corrosive fumes, high temperatures, and hazardous particulates. The motor remains in a clean, ambient environment while the impeller handles aggressive gases, ensuring extended motor life and eliminating the risk of spark ignition in volatile atmospheres. This design is essential for safe operation in chemical processing plants, laboratories, and industrial coating facilities.


Constructed with heavy-gauge mild steel casings and optional FRP or stainless steel linings, our fans withstand continuous exposure to acids, alkalis, and solvent vapors. The bifurcated configuration allows for easy motor maintenance without disturbing the ductwork or process airflow. Whether handling sulfuric acid fumes or halogenated compounds, our corrosive gas fan solutions deliver reliable ventilation while safeguarding your critical drive equipment from premature failure and costly downtime.

Robust Hazardous Duty Design

Engineered for the most demanding industrial applications, our hazardous exhaust fan systems comply with stringent safety standards for Zone 1 and Zone 2 environments. The bifurcated housing incorporates precision-sealed bearings, spark-resistant construction, and explosion-proof motor options to ensure complete operational safety. High-efficiency backward-curved or aerofoil impellers generate powerful airflow while maintaining low noise levels, making them suitable for both indoor process ventilation and outdoor fume extraction stacks.


As specialists in industrial ventilation fan technology, we offer extensive customization including chemical-resistant coatings, high-temperature alloys, and variable speed controls. Our bifurcated fans handle airflow volumes from 500 m³/hr to 50,000 m³/hr with static pressures up to 150 mm WG. Each unit undergoes rigorous factory testing for leakage, vibration, and performance verification. From pharmaceutical cleanrooms to petrochemical refineries, our solutions provide dependable air movement that protects personnel, equipment, and the surrounding environment from dangerous airborne contaminants.
