Typical Applications
Baghouse Systems: Selected according to required airflow and total system pressure, including pressure losses across filters, ductwork, and other system components.
Boiler Draft Systems: Used for combustion-air supply or flue-gas extraction. Cooling discs, extended shafts, and bearing arrangements can be configured according to gas temperature and thermal conditions.
High-Temperature Exhaust: Configurations are available for elevated-temperature exhaust applications. Maximum operating temperature depends on fan construction, cooling arrangement, gas conditions, and selected materials.
Abrasive Gas Streams: Uitable for abrasive dust applications such as cement, mining, and woodworking. Hardox 400/500 wear-resistant components can be specified for applicable impeller configurations to reduce erosion.
Corrosive Gas Exhaust: Stainless-steel wet-end components, including SS304 or SS316L, can be specified for applicable corrosive or humid gas applications. Material selection depends on gas composition, temperature, and corrosion conditions.
Airflow & Pressure Selection
Duty Point Determination: Fan models are selected according to the required airflow (Q) and system pressure at the design operating point, based on calculated system resistance.
Required Technical Data: Fan selection requires airflow, system pressure, gas temperature and composition, dust loading, altitude, installation conditions, and site voltage/frequency.
Operating Point Matching: The selected fan should operate within the recommended performance range to avoid unstable aerodynamic conditions and excessive vibration.
System Margin Considerations: Duct friction, elbow resistance, heat-exchanger pressure drop, filter loading, and other system losses are considered when determining the design pressure and motor rating.
Speed & Drive Selection: Drive arrangements and belt or coupling ratios are selected to achieve the target duty point while matching the available motor speed.
Customization Service
Impeller Materials: Q345B steel can be used for standard-duty configurations; Hardox 400/500 wear-resistant materials are available for abrasive applications; SS304/SS316L can be specified for applicable corrosive-gas conditions.
Discharge & Rotation: Discharge orientation and CW/CCW rotation can be configured for existing duct layouts.
Flanges & Inlets: Inlet cones, outlet flanges, dimensions, and bolt-hole patterns can be customized to match existing system connections.
Accessories & Coatings: Available options may include inspection doors, drains, split housings, reinforced bases, industrial coatings, high-temperature coatings, and epoxy finishes, depending on the fan configuration.
After-Sales Support
Spare Parts Availability: Drive belts, shaft seals, bearings, replacement impellers, and other wear components are available for scheduled maintenance.
Technical Support Services: Engineering staff provide remote installation guidance, operational troubleshooting, and spare-parts identification throughout the equipment's service life.
Warranty Coverage: A 12-month warranty against manufacturing defects is available, with the warranty start date and coverage defined in the sales contract.
FAQ
Q: What does the 12-month warranty cover?
A: It covers fan manufacturing defects. Motor coverage follows the motor manufacturer's terms. Wear, corrosion, and improper installation or wiring are excluded.
Q: What information is required for a quotation?
A: Please provide airflow, required system pressure, gas temperature and composition, dust loading, altitude, installation conditions, and voltage/frequency. Preliminary technical quotations are typically provided within 3–5 working days after the required project data is received.
Q: Can you provide a performance curve and technical drawing?
A: Performance curves and general arrangement drawings can be provided for the selected fan configuration. Additional documents, such as motor datasheets, material certificates, and inspection records, can be supplied according to project requirements.
Q: How are warranty claims handled?
A: The warranty starts from shipment or commissioning, as specified in the contract. Claims require photos, operating data, and the serial number for diagnosis.
Q: What is the lead time?
A: Standard configurations typically ship within 25–35 days. Custom configurations, high-temperature designs, and wear-resistant impeller arrangements typically require approximately 40–55 days. Final lead time is confirmed with the project quotation.
Q: Are spare parts available?
A: Belts, shaft seals, bearings, and impellers can be supplied with the initial order or purchased later. A spare-parts list is recommended at handover.
