Fan Construction
Impeller: Backward-curved or radial-bladed centrifugal impeller with dynamically balanced rotating assembly.
Housing: Heavy-gauge welded housing in carbon steel, SS304, SS316L or FRP.
Shaft & Bearings: Steel shaft with self-aligning pillow block bearings for continuous fan operation.
Drive: Direct-drive or belt-drive assembly with motor and fan shaft arrangement.
Discharge: Multi-position housing with configurable discharge orientation for different outlet directions.
Air Conditions & Material
Non-corrosive fumes: Carbon steel housing and impeller.
Corrosive vapors: SS304, SS316L or FRP housing and impeller; Halar, ECTFE, PTFE or phenolic epoxy coatings for additional corrosion protection.
Particulate-laden air: Radial-bladed impeller with heavy-gauge carbon steel or stainless steel construction for dust-containing exhaust.
Elevated-temperature air: Temperature-rated bearings, shaft components and motor for operation above standard ambient conditions.
Chemical exposure: SS316L, FRP or chemical-resistant coated construction for acid, alkali and solvent fumes.
System Matching
Airflow: Required operating airflow at the fan inlet or system connection point.
Static Pressure: Total resistance from ducts, elbows, dampers, filters, scrubbers, dust collectors and discharge sections.
Duct Connection: Inlet/outlet diameter, flange dimensions and discharge orientation.
Power Supply: Motor voltage, frequency and phase.
Installation Space: Fan footprint, mounting dimensions and maintenance clearance.
Accessories: Dampers, shaft seals, vibration isolators, weather hoods and bird screens where required.
Product Features
High Static Pressure Capability: Centrifugal impeller design provides the pressure required for long duct runs and resistance from filters, scrubbers and dust collectors.
Low Rotational Imbalance: Two-plane dynamic balancing reduces mechanical imbalance in the rotating assembly.
Corrosion-Resistant Construction: SS304, SS316L, FRP and chemical-resistant coatings provide construction options for corrosive exhaust conditions.
Multi-Position Discharge: Adjustable housing orientation supports different outlet directions and duct layouts.
Applications
Chemical Processing: Acid mist, solvent fumes, caustic vapors and other process emissions.
Metal Finishing & Electroplating: Chemical vapors and contaminated process air.
Welding & Cutting: Fume extraction from production and fabrication areas.
Manufacturing Plants: Centralized removal of process fumes and contaminated air.
Wastewater Facilities: Odor, chemical vapor and process exhaust removal.
Dust & Fume Collection: Connection to filters, scrubbers or other air-cleaning equipment.
Maintenance
Impeller: Remove accumulated dust or deposits and inspect blades for corrosion, wear or damage.
Bearings: Check bearing temperature, operating noise and lubrication condition.
Motor: Inspect terminals, cooling passages and operating temperature.
Belt Drive: Check belt tension, wear and pulley alignment on belt-driven units.
Housing & Connections: Inspect fasteners, duct connections, leakage and corrosion.
Filters & Scrubbers: Monitor loading and pressure drop where the fan operates with air-treatment equipment.
Vibration: Check for abnormal vibration after cleaning, maintenance or replacement of rotating components.

FAQ
Q: What is the difference between an industrial fume exhaust fan and a general ventilation fan?
A: An industrial fume exhaust fan is designed for contaminated process air containing fumes, vapors, gases or particulates, with heavier-duty construction for industrial exhaust systems.
Q: Can an industrial fume exhaust fan replace an existing exhaust fan?
A: Yes. A replacement can be supplied using the existing fan model, nameplate data, dimensions and connection details as the reference.
Q: Can the fan be connected to a scrubber or dust collector?
A: Yes. The fan can be used as part of an exhaust system with scrubbers, filters and dust collectors.
Q: What type of drive is used on an industrial fume exhaust fan?
A: The fan is available with either direct drive or belt drive, depending on the required fan arrangement.
Q: Can the fan be supplied for outdoor installation?
A: Yes. Outdoor installations can be supplied with weather-protection components such as weather hoods and protective screens.
Q: What documents are available with the fan?
A: Typical project documentation includes general arrangement drawings, fan performance data, motor information, operation and maintenance documentation, and applicable test records.
Q: How is the fan performance verified before shipment?
A: The assembled fan can undergo checks for rotation, operating condition, vibration, dimensions and final assembly before shipment.
Q: Can the fan be supplied for OEM or project orders?
A: Yes. Fan dimensions, materials, motor specifications, connections and accessories can be incorporated into project-specific orders.
