The fan casing is made of galvanized steel sheets internally lined with heat- and sound-insulation layer. The
round spigots are rubber sealed for airtight connection to the air ducts, Fig. 2.
The fan is equipped with a bipolar asynchronous motor with an external rotor and a centrifugal impeller
with backward curved blades. The motor is equipped with built-in overheating protection with automatic reset.
The motor ball bearings with a specially selected lubricant reduce the fan noise and ensure maintenance-free
operation. The model KSB...M is equipped with rubber anti-vibration mounts for extra vibration absorption.
The model KSB…S is equipped with a high-powered motor.
The model KSB…K1 with mineral wool insulation is designed for air extract only.
