4-72 Centrifugal
Ventilation Fan
The 4-72 centrifugal ventilation fan is used for factory ventilation, workshop exhaust, equipment room air supply and general industrial airflow systems. It is suitable for clean air or non-corrosive gas under ordinary ventilation conditions.
QIYUE FAN can help review model selection according to airflow, total pressure, fan speed, motor power, rotation direction, outlet angle and installation layout.
General-Purpose Centrifugal Fan for Industrial Airflow Systems
The 4-72 centrifugal ventilation fan is a general-purpose centrifugal fan commonly used in industrial ventilation systems. It can support air supply, exhaust ventilation, workshop air exchange, equipment room ventilation and airflow circulation where stable air volume and suitable pressure are required.
This fan series is mainly used for conveying ordinary air or non-corrosive gas. When the working medium contains heavy dust, corrosive gas, high-temperature air or flammable gas, the fan material, motor configuration, sealing method and protection requirements should be reviewed before selection.
QIYUE FAN can help review the suitable 4-72 centrifugal fan model according to airflow, total pressure, speed, motor power, outlet angle, rotation direction and installation space. If you already have an old fan model, drawing or parameter table, we can compare the existing data and provide a practical selection suggestion.
Basic Product Information
Suitable Conditions and Special Review Cases
For dusty air, high-temperature gas, corrosive gas or explosion-proof conditions, please review the working medium before selecting the fan series. QIYUE FAN can recommend dust collection fans, boiler and high-temperature fans, corrosion-resistant fans or explosion-proof fans according to the project condition.
4-72 Performance Parameter Table
The following 4-72 centrifugal fan performance data is used for preliminary model selection. Final selection should be confirmed according to airflow, total pressure, speed, motor power, duct resistance, installation direction and working conditions.
Note: Detailed performance data should be checked before quotation. For dust-laden air, high-temperature gas, corrosive medium, long duct resistance or continuous heavy-duty operation, please send the working condition for review.
How to Select a 4-72 Fan
A 4-72 centrifugal ventilation fan should be selected according to actual system resistance and airflow demand. The model name alone is not enough for accurate selection. Buyers should confirm the required air volume, total pressure, medium condition, working temperature, speed, motor power and installation direction.
Air Volume
Required airflow or current fan performance data.
Total Pressure
Required pressure, static pressure or duct resistance information.
Medium
Clean air, dusty air, hot air, corrosive gas or other gas condition.
Installation
Rotation direction, outlet angle, base frame, motor position and duct connection.
4-72 vs 4-79 Centrifugal Ventilation Fan
For general ventilation projects, buyers may compare the 4-72 and 4-79 centrifugal ventilation fan series according to airflow, pressure, installation space and working condition. Both are used for ordinary air or non-corrosive gas, but the final model should be selected by actual system parameters.
| Item | 4-72 Fan | 4-79 Fan |
|---|---|---|
| Main Position | General industrial ventilation | General ventilation with different performance range |
| Typical Use | Workshop, warehouse, equipment room | Factory, building, industrial airflow |
| Medium | Clean air or non-corrosive gas | Clean air or non-corrosive gas |
| Selection Basis | Airflow, pressure, speed, installation direction | Airflow, pressure, site layout, fan arrangement |
For similar general ventilation projects, buyers can also review the 4-79 centrifugal ventilation fan according to airflow, pressure and installation layout.
Typical Application Areas
Factory Ventilation
Air exchange and exhaust for industrial buildings, workshops and production areas.
Workshop Exhaust
Exhaust support for hot air, odor, smoke and general process air discharge.
Air Supply Systems
Fresh air supply and auxiliary air delivery for suitable industrial environments.
Equipment Rooms
Ventilation and heat discharge support for equipment rooms and machinery areas.
Warehouse Airflow
Air circulation and ventilation support for storage areas and large indoor spaces.
Supporting Ventilation
Airflow support for general industrial ventilation projects and equipment systems.
Choose Other Fan Series by Working Condition
For dust-laden airflow and dust collector systems. Boiler & High Temperature Fans
For flue gas, boiler draft and high-temperature exhaust. Corrosion Resistant Fans
For corrosive gas and chemical exhaust systems. Explosion Proof Fans
For working sites requiring explosion-proof motor configuration.
Inspection Before Shipment
Before delivery, the fan can be checked according to order requirements, including appearance, dimensions, welding condition, assembly quality, impeller balance, motor matching and packing condition. For project orders, inspection photos or basic production records can be provided according to communication requirements.
Packaging can be arranged according to domestic transportation, export shipment, container loading and project delivery requirements. Spare parts, nameplate information, special packing and documentation support can be confirmed before production.
