Exhaust Medium & Operating Conditions
Dust-Laden Air: Wood dust, cement dust, metal particles → wear-resistant carbon steel impeller.
Hot Gas: Furnace, kiln, dryer exhaust → high-temperature shaft sealing and bearing arrangement.
Moist Gas: Humid or condensation-prone air → SS304 or SS316L wetted components.
Corrosive Gas: Chemical vapors and corrosive process gases → SS316L or corrosion-resistant surface treatment.
Clean Air: Non-corrosive, low-dust process air → Q235B carbon steel construction.
High-Pressure Exhaust Performance
High Static Pressure: Centrifugal impeller design generates up to 3,500 Pa static pressure against resistance from ducts, filters, and cyclones.
Stable Airflow: The impeller maintains steady air movement as system resistance increases.
High-Temperature Exhaust: Handles exhaust temperatures from -20°C to 250°C without compromising continuous air extraction.
Low Vibration: Dynamic impeller balancing to ISO 1940 Grade 2.5 limits residual imbalance and reduces vibration.
Continuous Operation: Designed for continuous 24/7 operation with stable airflow and controlled mechanical vibration.
Applications

FAQ
Q: Can a high pressure exhaust fan replace an existing fan?
A: Yes. Replacement orders can be matched using the existing fan model, nameplate data, drawings, and mounting dimensions.
Q: What information is shown on the fan nameplate?
A: The nameplate identifies the fan model and key operating information required for installation, operation, and future parts ordering.
Q: Is a high pressure exhaust fan suitable for a new ventilation project?
A: Yes. The fan can be supplied as part of a new industrial exhaust or process-air system.
Q: Can the fan be supplied with a motor?
A: Yes. Motorized assemblies can be supplied with the motor and drive arrangement specified in the order.
Q: Can spare parts be ordered years after the original purchase?
A: Replacement parts can be ordered using the original fan model, serial number, or part information.
Q: What drawings are provided for installation?
A: 2D/3D drawings and technical documentation can be provided for equipment layout, connection, and installation work.
Q: Can one fan model be used for multiple production lines?
A: The same fan model can be used across multiple lines when the required equipment configuration and operating conditions are the same.
Q: What is the difference between direct-drive and belt-drive fans?
A: Direct drive connects the motor directly to the fan shaft, while belt drive uses pulleys and belts between the motor and fan shaft.
