NTHZ
HVAC Double Inlet Fan with Backward curved blades, with ForeFinger ®.
- Steel impeller with 11 backward-curved blades, welded and painted
- Inlet cone with Forefinger (patented)
- Housing with Pittsburgh closure
- Trapezoidal cut-off
- Low-maintenance ball bearing
Very high efficiency
Thanks to:
- the new steel impeller with 11 backward curved blades;
- 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 under DIN 24166 CLASS 1.
It is ERP 2015 compliant.
NTHZ series is AMCA certified.
