Soler & Palau SP200100030 Duct fan TD Mixvent 350/125

TD 350/125 ducted two-speed fan from Soler & Palau with plastic impeller and ball bearings. Quality fan with quiet operation for 125 mm diameter pipe. Flow rate 330/250 m3/h. Enclosure The enclosures of the TD-160 to TD-800 fans are made of plastic, the TD-1000 to TD-6000 models are made of galvanised steel sheet with epoxy coating. The housing consists of a mounting rail with two throats and a motor which is connected to the throats by quick-release clips. The design allows the motor section to be removed without the need to disconnect the pipework. The impeller The impellers of fans TD-160 to TD-800 are made of plastic, the impellers of TD-1000 to TD-6000 are made of aluminium. Motor The inverter motors in the TD-160 to TD-350 fans have dual windings, allowing for dual speed operation. Fans TD-500 to TD-2000 have triple windings. TD-4000 and TD-6000 have one winding and can be controlled by changing the voltage. The motors are equipped with thermal fuse (TD 160-TD 350) or thermal protection (TD 500-TD 6000). The bearings are ball bearings with grease packing for life. Insulation class B, protection IP44 (TD 250, 350, 800-2000), insulation class F, protection IP44 (TD 500), insulation class F, protection IP54 (TD 4000, 6000). TD and TD-T fans are for 230 V, except TD 4000 TRIF (230/400 V) and TD 6000 TRIF, where the supply voltage is 400 V. Terminal blocks The terminal block is located on the fan housing, and on some types it contains a start-up capacitor. Speed control For AC motors with double windings (TD 160-350), the speed is switched in two stages using REGUL 2 or COM 2 controllers or by changing the voltage with REB (continuous control) or REV (five-stage control) controllers. For triple winding motors (TD 500 - TD 2000), the speed is switched in three stages using COM 3 or INT 4P controllers or voltage change control with REB (stepless control) or REV (five stage control). The TD 4000 and 6000 can only be regulated by changing the voltage. The TD 4000 and 6000 TRIF can be regulated by changing voltage or frequency converters. TD-T with one winding and built-in timer cannot be regulated.
