Product Description Centrifugal Fan S4-72-11 centrifugal ventilatorProduct showProduct StructurePerformance selection tableCentrifugal fans, also known as radial fans, are widely used in various industrial and commercial applications due to their unique design and performance characteristics. Here are some key advantages of centrifugal fans:1. High Pressure Generation* Centrifugal fans excel in generating higher static pressure compared to axial fans, making them suitable for systems with significant resistance (e.g., ductwork, filters, or long pipelines).* Ideal for applications requiring air movement against high resistance, such as HVAC systems, industrial drying, or dustcollection.2. Energy Efficiency at High Pressure* They operate more efficiently than axial fans in high-pressure applications, reducing energy consumption for systems with restrictive airflow paths.3. Versatility in Airflow Direction* The airflow direction can be easily customized (e.g., tangential, radial, or axial discharge) by adjusting the impeller andhousing design.* Common configurations include forward-curved, backward-curved, and radial blades, each optimized for different pressure and flow requirements.4. Durable and Robust Construction* Centrifugal fans are built to handle harsh conditions, including high temperatures, corrosive gases, or abrasive particles(e.g., in industrial exhaust systems).* Materials like stainless steel or coated impellers enhance longevity in demanding environments.5. Quiet Operation* Generally quieter than axial fans at similar pressures, especially backward-curved blade designs, which reduce turbulence and noise.* Suitable for noise-sensitive environments like offices or hospitals.6. Wide Range of Flow Rates* While optimized for pressure, centrifugal fans can also be designed for varying flow rates by adjusting impeller size, speed, or blade shape.7. Handling Contaminated Air* Radial blade designs (e.g., paddle-wheel or open impellers) are effective for moving air with dust, moisture, or particulates without clogging.* Used in woodworking, mining, and wastewater treatment.8. Stable Performance Under Load Variations* Less prone to performance fluctuations when system resistance changes, ensuring consistent airflow in dynamic conditions.9. Flexible Installation Options* Can be configured in multiple orientations (horizontal/vertical) and integrated into complex duct systems.10. Low Maintenance* Fewer moving parts than some fan types, with easy access for cleaning and servicing in many designs.Common Applications:* HVAC systems (air handling units, furnaces).* Industrial processes (pneumatic conveying, combustion air supply).* Pollution control (scrubbers, fume extraction).* Drying/cooling systems (food processing, textiles).Comparison with Axial Fans:While axial fans are better for high-volume, low-pressure airflow (e.g., cooling towers), centrifugal fans dominate inhigh-pressure, moderate-flow scenarios.Model A: ModelNo.Revolving Speedr/minTotal pressurePaAir volumem3/hMotor powerKW2.8A2900588-9511330-24501.53.2A2900784-12451975-36402.21450196-313991-19101.13.6A29001068-16182930-540831450274-4021470-27101.14.0A29001314-20004020-74205.51450333-5002010-37101.14.5A29001667-25305730-105807.51450421-6372860-52801.15.0A29002196-31777950-14720151450549-7943977-73582.26.0A1450784-11376840-127204960343-5004250-83701.5Model C:ModelNo.Revolving Speedr/minTotal pressurePaAir volumem3/hMotor powerKW6C22401883-272610600-1960018.520001500-21779500-176001118001216-17658520-158007.51600961-13937560-140005.51250579-8435920-1100031120471-6865300-98002.21000373-5394730-87502.2900304-4414250-78502.2800226-3333780-70001.18C18002363-311920100-348003016001844-247117920-310002212501138-151014000-24200111120912-120612500-216507.51000726-96111200-193005.5900588-77510050-174004800461-6188960-155003710373-4817920-137102.2630284-3827040-122002.210C12501863-234434800-501503711201491-188331200-450002210001187-150027800-4010018.5900961-121625050-3610015800765-96122150-3210011710598-75519780-285007.5630471-59817540-252805.5560373-47115600-224703500294-38213910-20100312C 11202148-271753800-775007510001716-216748100-69300559001383-174643200-62200308001098-138338600-5570022710863-108934200-4950018.5630686-86330400-4390015560539-67727000-389007.5500432-53924100-348005.5450343-44121650-312004400275-35319280-278003Model D:ModelNo.Revolving Speedr/minTotal pressurePaAir volumem3/hMotor powerKW6D1450785-11386840-127204960343-5004520-83701.58D14501530-202016200-2799018.5960677-89210750-185605.5730392-5208150-14150310D14502501-315840400-58200559601098-138326730-3850018.5730637-80420800-293007.512D9601579-199146100-9650037730922-114735000-5050018.5 Technical parameter:Advantages:Advantage:This ventilator has the features such as: High efficiency, low noise, stable pressure curve and anti-corrosion and energysaving,convenient installation, wide application.Model:This kind of centrifugal fan are divided in to A\C\D three connect way, type A means the motor connect with the impellerdirectly,the C type means the motor and the impeller connected by the belt, type D means connected by the coupler.
