EC Plug Fans with I Impeller
Latest Gen Aluminium EC Plug Fans Designed for High Airflow Applications
The latest I-Series volume-flow oriented five-blade aluminium backward curved impeller offers improved efficiency and less noise than earlier designs or competitive products. Depending on fan size and operating point, our new impeller increases efficiencies by up to 11% while reducing noise levels by more than 12%. It is available with Gen3 and Gen3+ EC motors operating with up to 7kW of power input.
Perfectly Designed to Reduce Turbulent Downstream Air
The I impeller has 5 meticulously designed hollow profiled, aerofoil section blades contoured in sheet aluminium. The design significantly reduces the turbulent downstream air produced by traditional backward curved impellers. The effect of this reduction is significantly reduced noise and in-application efficiency.
Our stocked I series EC plug fans are in CCSI, contact us for more information.
The I Series is a one of our most popular EC plug fans, therefore we stock fast moving references. Contact our OEM team to discuss our current lead times and availability.
100% speed controllable, the more powerful generation 3+ EC motor available on 3~ I series plug fans, automatically adjusts to the actual input power across the entire range, allowing reduced inventory cost and easier design-in. The 3~ 50-60Hz motors are rated IP54 and UL-R motor class F. Gen 3+ motors are 30% more powerful than previous versions.
The operating temperature range is -25C to +40C at full speed.
Gen 3+ motors exceed in accordance with IEC 60034-30-2 minimum requirements for IE5 Ultra Premium Efficiency.
Electronic with integrated terminal box and environmental resistant cable glands. 100% speed controllable with integrated motor protection and soft start. ModBus RTU interface integrated. Busconfiguration possible on site.
Technical Data & Drawings
When comparing the B series and I series impellers, using a smaller I impeller with a smaller motor can result in a cost saving of up to 10% when compared against similar operating characteristics. This can be seen in the comparison below. The I impeller shows a 450 diameter impeller, while the B impeller shows a 500 diameter impeller and a motor one size up. Sound power is also significantly reduced.
