TNHT 710 Ecowatt roof fan

Cabinet

is designed for horizontal (TNHB, TNHT) or vertical (TNVB, TNVT) air exhaust. The fan base is made of galvanized steel sheet, the frame and motor brackets are also electroplated. The fan design optimizes airflow, which increases efficiency and reduces noise. The motor is connected directly to the fan shaft. The fan blade, beams, control cover and deflectors for vertical air outlet are painted RAL 7024 (grey) with very good weather and UV resistance.

Running wheel

The fan is radial with backward curved blades, made of galvanized steel sheet. It is statically and dynamically balanced.

Motor

It is DC, special EC, with external rotor for 1f 230 V/50 Hz (TNHB/TNVB 355-450) or 3f 400 V/50 Hz (TNHT/TNVT 500-710) power supply. The motors are equipped with a thermal fuse as standard. Motor insulation is Class F. Bearings are grease filled for life. Continuous operating temperature -20 to +120 °C, in OTK mode F400 (120).

Screwdriver

with a revision switch is located on the fan housing.

Mounting

The fan is mounted horizontally with the accessories (with the motor axis vertically).

Speed control

is carried out using a potentiometer located in the terminal block or a remote CVF or REB Ecowatt potentiometer. In addition, a signal from external devices (CO2, temperature and relative humidity sensors) or an external pressure sensor with a transducer and 0-10 V or 4-20 mA output can be connected.

Rotation direction

is only possible in one direction, as indicated by the arrow on the fan housing. The opposite direction of rotation may cause motor overload, and the fan will also experience increased noise.

Description

Fans are suitable for extracting smoke and hot air in case of fire, exhausting polluted air from commercial and industrial premises and professional kitchens. Air temperature up to 120 °C.
