Industrial Exhaust Fan Range
Choose the Structure Around the Installation
Start with the wall opening, airflow requirement and operating environment. We will then match the frame, motor, blade, shutter or guard to the intended use.
Weather protection
Exhaust Fans with Shutters
Shutter or louver options help protect the opening when the fan is not operating and can be matched to the installation conditions.

Added protection
Guarded Exhaust Fans
Protective guard and cover configurations can be selected according to access, installation position and destination-market safety needs.

Before You Choose
Fan Diameter Alone Is Not Enough
A reliable quotation starts with the installation and duty—not only an inch size. Share the following information so we can avoid an undersized motor, an incorrect frame or an unsuitable electrical setup.
- Wall opening or required frame dimensions
- Target airflow in m³/h or CFM, if available
- Voltage, frequency and phase
- Heat, moisture, grease, dust or corrosive exposure
- Daily operating hours and airflow direction
- Order quantity, destination market and packing preference
| Information | Example | Why It Matters |
|---|---|---|
| Installation opening | Width × height or diameter | Confirms frame fit and mounting structure |
| Air volume target | m³/h or CFM | Guides motor and blade selection |
| Power supply | Voltage / frequency / phase | Defines the electrical configuration |
| Operating environment | Heat, steam, dust or grease | Affects material and protection decisions |
| Duty cycle | Hours per day | Helps match the motor to expected use |
| Market and quantity | Country + order volume | Confirms compliance, MOQ and packing |
If the airflow target is unknown, share the room dimensions, heat or moisture source and desired air-change goal. Final system sizing should be confirmed by the buyer's qualified ventilation engineer.
Application Support
Industrial Ventilation for Different Working Environments
The same fan is not suitable for every space. Tell us what must be removed—heat, stale air, moisture, smoke, odors or process air—and how the fan will be installed.
Factories & Workshops
Remove accumulated heat and stale air from production areas while supporting more consistent air exchange.
Warehouses & Logistics
Support air exchange in storage, loading and distribution spaces where warm, stagnant air can build up.
Commercial Kitchens
Help extract heat, moisture and odors where the fan specification and cleaning access suit the kitchen environment.
Agriculture & Greenhouses
Improve ventilation in greenhouse or livestock environments after humidity, dust and corrosion exposure are reviewed.
Special environments require a separate technical review.
High-temperature, explosion-risk, chemical or heavily corrosive applications must not use a standard exhaust fan by assumption. Send the required temperature range, hazardous-area classification and local certification standard before model selection.
Built Around the Specification
Industrial Exhaust Fan Details That Can Be Confirmed
Performance and service life depend on the complete configuration. We confirm the motor, blade, frame, protection and electrical details before production.
Motor & Bearing Options
Copper-winding and ball-bearing configurations are available according to the model, duty and target market.
Balanced Fan Blades
Blade material, diameter and profile are matched to the intended airflow and motor configuration.
Metal Frame & Housing
Frame dimensions, mounting points, housing structure and finish can be confirmed against the opening.
Shutter or Louver Options
Opening method, material and installation direction are selected according to the product structure.
Guard & Cover Details
Protective grille, cover and access requirements can be specified for the intended installation.
Market-Specific Power Setup
Voltage, frequency, phase, cable, plug, rating label and certification needs are confirmed by market.
OEM / ODM Exhaust Fans
Build the Right Exhaust Fan for Your Market
We support standard models and specification-based OEM projects. Your quotation is prepared around the actual opening, airflow duty, operating environment, compliance needs, quantity and packing method.

Production & Quality Control
From Approved Specification to Export Packing
Incoming materials, assembly details and finished-product checks are controlled against the approved order specification to support repeat-order consistency.
01 / Materials
Incoming Material Check
Motor, blade, frame, guard, shutter and electrical components are checked against the confirmed order requirements.
02 / Inspection
Process & Final QC
Applicable electrical safety, rotation, current, vibration, noise and appearance checkpoints are completed before packing.
03 / Shipment
Export-Ready Packing
The product and carton structure are confirmed before shipment, with component protection and shipping marks prepared for the order.
Export Packing
Confirm Protection Before Container Quantity
Industrial exhaust fans vary in frame depth, shutter structure and guard design. We confirm the product configuration and carton dimensions before calculating a reliable loading quantity.
- CBU or component packing evaluated by model
- Protection for blades, motor shafts, frames and shutters
- Neutral or customized carton artwork
- Shipping marks and spare-parts plan by order
| Packing Decision | What We Confirm | Buyer Benefit |
|---|---|---|
| Product structure | Frame, motor depth, guard and shutter | Correct carton size and protection |
| Packing form | CBU or separated components | Balance assembly work and loading volume |
| Inner protection | Blade, shaft, corners and moving parts | Lower transit-damage risk |
| Carton & marks | Artwork, strength and shipping marks | Market-ready identification |
| Loading plan | Final carton dimensions and quantity | More reliable freight comparison |
Container quantities should be treated as model-specific. Final figures are calculated after the fan structure and packing method are approved.

Industrial Exhaust Fan FAQ
Questions From Importers and Project Buyers
These are the main technical and commercial points we confirm before preparing a model-specific quotation.
What is the MOQ for industrial exhaust fans?
Our standard MOQ is 1,000 pieces per model. The exact MOQ can vary when the order requires a custom frame, motor, finish, logo, packaging or other non-standard components.
Which details are needed for an accurate quotation?
Please provide the installation opening, target airflow if available, application, operating environment, daily working hours, voltage, frequency, phase, destination market, quantity and packing preference.
Can you recommend a fan from the room size?
We can help shortlist a practical model when you provide the room dimensions, heat or moisture source and air-change target. The final ventilation-system design and airflow requirement should be confirmed by the buyer's qualified project engineer.
Can the voltage, motor, shutter and packaging be customized?
Yes, depending on the selected model and order quantity. We can evaluate the motor, blade, frame, shutter or guard, voltage, frequency, label, color, logo and carton requirements.
Can a standard model be used for high-temperature or explosion-risk areas?
Not by assumption. High-temperature, explosion-risk, chemical and corrosive environments require a separate technical and certification review. Send the operating temperature, hazardous-area classification and local standard before selection.
What warranty and spare-parts support do you provide?
The standard warranty is one year. We generally provide 0.5% spare parts and troubleshooting guidance. If replacement parts cannot resolve a covered manufacturing issue, we can provide a replacement motor according to the agreed order terms.
Which certifications are available?
CE, CB, ERP and RoHS options are available for relevant models. Market-specific certification and installation requirements must be confirmed before quotation and production.
Need an Industrial Exhaust Fan for Your Market or Project?
Send the opening size, airflow target, application, power supply, quantity and destination market. We will prepare a suitable configuration and quotation.
