Fume & Smoke Exhaust Fan Types

Select the fan type according to the exhaust duty and medium.

Fan Type	Primary Duty	Typical Medium
Heavy Duty Smoke Exhaust Fan	Heavy-duty smoke extraction and life-safety ventilation	Fire smoke, high-temperature smoke
Industrial Smoke Exhaust Fan	Smoke evacuation in industrial and building ventilation systems	Structural fire smoke, thermal smoke
High Temperature Smoke Exhaust Fan	Continuous or emergency extraction of high-temperature gases	Hot smoke and process exhaust
Welding Fume Exhaust Fan	High-static-pressure fume extraction	Welding fumes, metal oxides, grinding dust
Industrial Fume Exhaust Fan	Continuous process exhaust	Corrosive vapors, toxic gases, particulate emissions

Fume & Smoke Exhaust Fan Applications

Metal Fabrication & Welding: Extraction of welding fumes, metal oxides, grinding dust, and thermal gas plumes.

Chemical & Pharmaceutical Processing: Handling of acid mists, solvent vapors, corrosive process gases, and other demanding process exhaust.

Commercial Kitchens: High-temperature extraction of grease-laden vapors and smoke.

Life-Safety & Infrastructure: Emergency smoke evacuation and stairwell pressurization for transit tunnels, high-rise buildings, and industrial complexes.

Temperature & Smoke Exposure

Temperature and exposure duration determine the required fan construction.

Duty	Available Configuration
Standard exhaust	Up to 80°C continuous
High-temperature exhaust	Up to 300°C continuous
Emergency smoke exhaust	Up to 400°C for 2 hours

Airflow, Pressure & Mechanical Configuration

The fan range is configured for different system resistance and air-volume requirements.

Parameter	Configuration
Airflow	1,000–120,000 CFM / 1,700–204,000 m³/h
Static pressure	Up to 3,500 Pa / 14 in. w.g.
Motor power	0.75–250 kW
Housing thickness	4–12 mm
Impeller	Backward-curved or radial blade
Shaft	42CrMo alloy steel
Bearing	Self-aligning spherical roller bearing

Material, Corrosion & Sealing Configurations

The exhaust medium determines the material and internal protection used for the airstream.

Exhaust Condition	Available Construction
General industrial exhaust	Q235 carbon steel
Stainless construction	304 / 316 stainless steel
Corrosive airstream	Fusion-bonded epoxy, Halar (ECTFE), rubber lining
Acid-containing exhaust	Acid-resistant ceramic topcoat

FAQ

Q: Can the fan be supplied for an existing duct system?

A: Yes. Existing duct and installation information can be incorporated into the fan configuration. GA drawings can be provided for dimensional and connection review before production.

Q: Can the fan be supplied with the required inlet and outlet connections?

A: Yes. Available accessories include inlet and outlet flexible connectors and companion flanges, allowing the fan configuration to be coordinated with the connected ductwork.

Q: Can the fan be configured for different motor standards?

A: Yes. The original specification lists motor compatibility with IEC, NEMA, ATEX, and UL hazardous-location requirements. The required motor standard should be specified with the project electrical requirements.

Q: Can the fan be supplied with project-specific inspection or NDT requirements?

A: Yes. Dye penetrant testing is available upon request, in addition to the standard fabrication and rotating-assembly inspection processes. Project-specific inspection requirements can be identified during quotation.

Q: What should be provided when replacing an existing fan?

A: For a replacement quotation, useful information includes the existing fan model, motor nameplate, airflow and pressure data, installation dimensions, connection dimensions, and available GA drawings. If the original fan data is incomplete, existing drawings and nameplate information can still be used as a starting point.

Q: Can you provide documentation before production?

A: Yes. GA drawings and wiring diagrams are available for project review, while test and material documentation can be supplied as part of the completed fan documentation package.

Q: Can spare parts be supplied with the fan?

A: Yes. Spare-parts documentation and O&M manuals are available as part of the documentation package, allowing the required maintenance items to be identified for the supplied configuration.
