Cabinet
It is made of galvanized steel sheet with black paint, mounting brackets and screws are electroplated.
Running wheel
is plastic, the "AMAX" shape is specially optimised for maximum flow and pressure with minimum noise. The impeller is pressed directly onto the motor.
Motor
EC motor with thermal overload protection. Bearings are ball bearings with grease packing for life. IP44 protection. Operating temperature -20 to +40 °C (TXBR Ecowatt) or -20 to +50 °C (HXBR Ecowatt).
Speed control
is carried out by means of a potentiometer located in the terminal block or by an external REB Ecowatt control. Additionally, an analogue 0-10 V input from a temperature, humidity or CO2 sensor.
Rotation direction
cannot be changed. In the wall-mounted version, the standard air flow is from the motor to the impeller, in the ducted version it is the other way around.
Clamps
is made of black plastic as standard. The terminal box is located on the motor (wall mounted) or on the cabinet (ducted). IP65 protection.
Mounting
is possible in any position of the motor axis. In case of horizontal mounting, condensate drain holes must be opened in the rotor. The casing must not transmit mechanical stresses from the pipework. A flexible connection to the pipework must be used.
Noise
emitted by the fan is given in the tables, measurements are taken at a distance equal to three times the impeller diameter (but at least 1.5 m) on the suction side.
