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 trapezoidal cut-off was developed to work with ForeFinger ®.

You get:

  • increase airflow and pressure. For the required volume and pressure, the fan can now run at a lower speed or 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 by DIN 24166 CLASS 1.

It is ERP 2015 compliant.

TZAF-FF series is AMCA-certified.
