Centrifugal fans
Two-side-suction fans with blades bent backwards, driven by motors via a belt transmission
- make it possible to obtain high pressures. One-speed or two-speed three-phase motors are
used to drive the fans. The motors are mounted on installation rails, ?tted with a tightening bolt,
making it possible to adjust the V-belts. Standard operating temperature is -15oC to +40oC.
Both at the fan and at the motor, the belt pulleys with a Taper-lock hub are installed, so the
disassembly is quick and simple. Depending on the load, V-belts characterized by SPA, SPB
or SPZ pro?les are used in transmissions. The fans are equipped with bearings of minimum
service life of 20000 hours. Depending on operating conditions, the fans are equipped with
maintenance-free bearings or bearings which require periodical lubrication.
