of the ring blower fans is based on the lateral ducts principle. The
blowers can operate as either exhaust or compression fans and are designed
for continuous service.
A special impeller forces the intake air to
follow a spiral path; the air is thus subjected to repeated accelerations
that permit achieving high pressure and vacuum values.
The impeller is assembled directly on the
motor shaft; all the rotating parts are dynamically balanced to ensure
absolute absence of vibrations.
The device features full die-cast aluminum
construction for maximum sturdiness and ease of handling.
No lubrication is required, since there are
no points of contact between the static and the rotating pants.
Special silencers assembled on both the
intake and delivery sides contribute to reducing noise to a minimum.
Our three decades of experience in the sector
and our ongoing commitment to research have made it possible to build
impellers with special characteristics such as to avoid the accumulation
of small foreign bodies, oil and dust inside the fan and thus avert the
risk of unbalancing, seizing up, etc.
One outstanding feature of the device of the
blower is that the air pumped always remains perfectly clean.
The exhaust fans require no lubrification
Quick and easy maintenance
The exhaust fans can be mounted in any
