1 SOUND-INSULATED FANS Series Inline centrifugal fans in heat- and sound-insulated casing with air flow up to 7 m 3 /h Purpose KSB fan design allows to use them in supply and exhaust ventilation systems in premises with high requirements to the noise level and with limited space for mounting. For example, the unit design includes a possibility of space-restricted installation above suspended ceilings. They are designed for mounting into Ø - mm air ducts. Design The fan casing is made of aluzinc. For easy installation and operation, the top cover of the fan is secured with a special lock. Warm and sound insulation is made of non-combustible mineral wool mm thick. To ensure better noise absorption, the inner surface of the insulation is made of a perforated metal sheet. The round connecting spigots are rubber sealed. Motor The fans are equipped with asynchronous motors with an external rotor and centrifugal impellers with backward curved blades. The motors are equipped with an integrated overheating protection with automatic restart. The use of ball bearings with specially selected lubricating oil guarantees low noise and makes the fan completely maintenance-free. Speed control The control can be either smooth or stepped and carried out with a thyristor or autotransformer regulator. Several fans can be connected to one controller, provided that the total power and operating current do not exceed the nominal parameters of the controller. Mounting Inline fans are designed for round air ducts. The fans are installed at an air duct junction. The use of flexible connectors requires fixation of the fan on the building structure by means of supports, mounts, or fixing brackets. The fan can be fixed in any position, taking into account the air flow direction indicated by the arrow on the fan casing. While mounting the fan provide enough access for servicing and repair operations.
