HVAC Double Inlet Fan with Airfoil Backward curved blades, with Forefinger® device.

• Steel impeller with 10 Airfoil blades, completely-welded and painted
• Inlet cone with Forefinger (patented)
• Housing with Pittsburgh closure
• Trapezoidal cut-off
• Low maintenance ball bearing

Thanks to:

• the new steel impeller with 10 backward curved airfoil shaped blades, completely welded and painted;
• the precision engineered inlet cones fitted with the innovative ForeFinger ®;
• the integrated design of the trapezioidal cut-off, developed to work with ForeFinger ®.

You get:

• increase airflow and pressure. For a required volume and pressure the fan can now run at a lower speed or, alternatively, you can select a smaller fan.
• more uniform flow at the fan outlet. This can result in better filter and coil efficiency in the air handling unit.
• wider working field with high efficiency. This means more flexibility.
• significant reduction of noise generated by the blades, especially in the low frequency range.

The performance data are in accordance with DIN 24166 CLASS 1.

It is ERP 2015 compliant.
