Item Number: 2030


Integral thermal contacts

Low noise level

Compact construction

The KVO 355-400 models have a single-inlet centrifugal fan with forward-curved blades and a maintenance-free external rotor motor. In all KVO models, the motor and impeller are mounted on the cover for easy cleaning and maintenance. To protect the motor from overheating, the fans have integral thermal contacts with external leads for connection to a motor protection device. The fans can be installed in any position, and are easy to connect to spiral ducts using FK mounting clamps. The lid is insulated with 40 mm rockwool. The casing is manufactured from galvanised sheet steel.
