Industrial Fan Inquiry, Replacement & Spare Parts Support
Choose the route that matches your project. Complete parameters are useful, but not required for the first inquiry. If pressure is unknown, send the duct and equipment information instead. For replacement projects, a nameplate, drawing, site photo or existing dimensions can still be used to begin the review.
Start With What You Know

Start With What You Know
- Airflow or process capacity
- Pressure, or duct / resistance information
- Medium, temperature, dust / corrosion condition
- Voltage, frequency, quantity and destination
- Nameplate, drawing or photos for replacement
Fan Selection, Replacement & Spare Parts
Review the fan selection process, or send the information you already have by email. Email is preferred for drawings, specifications, datasheets, nameplates and project files. WhatsApp is useful for quick site photos, nameplates and follow-up communication.
Start With The Information You Already Have
Airflow + Pressure Are Available
Application / process · Required airflow · Static or total pressure · Normal / peak temperature · Gas / dust / corrosion condition · Voltage / frequency · Quantity & destination
Airflow + Pressure → Fan Family → Performance Curve → Size / RPM / Motor → Quotation
Airflow Is Known, Pressure Is Not
Duct size · Approximate duct length · Elbows / branches / transitions · Filter / baghouse / cyclone / scrubber · Vertical rise · Outlet route · Site sketch / photos
Airflow → Duct / Equipment Data → Resistance Review → Pressure Basis → Fan Family / Model → RFQ
Open Static Pressure Unknown Guide →Replace an Existing Fan
Fan nameplate · Motor nameplate · Full fan photos · Old GA drawing / curve · Inlet / outlet / foundation dimensions · Rotation / outlet angle · Current operating problem
Replacement Parts
Fan model / serial number · Part required · Impeller / casing / shaft · Bearing / base / coupling · Material · Quantity · Part photo / dimensions / drawing
Technical RFQ Data
Airflow & Pressure
m³/h, m³/s or CFM; Pa, kPa or mmH₂O. Mark pressure as “Unknown” if not available.
Temperature & Gas Condition
Normal / maximum temperature, dust, humidity, corrosion or other process conditions.
Voltage & Frequency
Voltage, Hz, phase and any motor protection or VFD requirement.
Quantity & Destination
Quantity, destination country / city and any delivery or documentation requirement.
Email Is The Preferred Channel For Technical RFQs
For drawings, specifications, datasheets, nameplates and project files, email is preferred because it keeps the technical record together. WhatsApp is useful for quick site photos, nameplates and follow-up communication.
Recommended attachments: specification sheet, GA drawing, duct sketch, fan / motor nameplate, full equipment photos and any existing performance data.
