Cabinet
is made of steel sheet coated with black epoxy paint, the brackets and screws are also electroplated.
Running wheel
is made of Al alloy. The impeller is statically and dynamically balanced, the operating temperature range is from -20 to +55 ˚C (sizes 15-710 except TCBT/4-710) or from -20 to +40 ˚C (size 800 and TCBT/4-710).
Motor
asynchronous with short armature, stator with cooling fins, black epoxy lacquer finish with Class F insulation. grease-filled ball bearings for life. IP55 protection. For sizes 710-1000, consult our engineers for IA/IN and te values.
Speed control
By default, fans cannot be electrically or electronically controlled. PTC motors with thermal protection can be supplied on request, regulated by recommended frequency converters.
Rotation direction
It is possible to order an impeller for the opposite direction of rotation. For the wall-mounted version, the standard airflow is from the motor to the impeller, for the ducted version it is the other way around.
Clamps
is in a non-explosive design. The terminal box is located on the motor (wall-mounted version) or on the casing (ducted version).
Mounting
Fans in each position of the motor axis. The cabinet must not transmit mechanical stresses from the piping. A flexible connection to the piping must be used.
Noise
emitted by the fan is given in the tables, measured in the free acoustic field at a distance equal to three times the impeller diameter (but not less than 1,5 m), on the intake side.
Instructions
Inquire about special designs and currently available special accessories. Ask for information on delivery dates. Please note: the fans are in a special design for the Czech Republic. Spare parts supplied as standard by the manufacturer or other commercial organisations cannot be used. The TCBT/4-315 Ex fans can only be operated in a 3 x 400 V network in a Y connection. The values of In, Ia/In and Te specified in the fan certificates are the decisive basis for the installation of the safety elements and thus the safe operation of the fans. These values must be checked carefully after delivery of the fan.
