Ambient temperature must be between -15°C and + 40°C. Humidity must not exceed 80%.
Roller motor bearings must be lubricated whenever the machine is stored for more than 2 years under
proper conditions and 1 year under adverse conditions (high humidity, salty air or sand, or dust).
Before the new start-up,
check the insulation resistance of the motor. With value ≤ 1 kΩ per volt of nominal
voltage, the winding has dried out.

OPERATING PRINCIPLE
Side channel blowers and exhausters have been developed upon the theory of the regenerative downflow.
Both suction and discharge air passages drive to a toroidal chamber, where the radial blade impeller is
located, representing the core of the equipment.
The fluid is forced inside the toroidal channel by the centrifugal energy given by the impeller and released
towards the inner side of the impeller blades where a further acceleration provides the fluid with an
helicoidally trajectory with a consequent progressive increase of energy.
The pitch of the helicoidally trajectory changes in proportion with pressure variation between suction and
discharge. The pitch is able to self-calibrate according to the load acting on the fluid. The gas is free of
pollution and keeps a linear flow without pulsations. The absence of vibrations and a low noise level are
further advantages and contribute to ease the installation.

TECHNICAL DESCRIPTION
All
SC
blowers and exhausters are made of aluminum alloy. Since there is no contact between the static and
rotating components and bearings are life-pre-lubricated no lubrication is needed.
All
SC
machines are manufactured according to 2006/42/EC, 2006/95/EC, EN ISO 12100:2010 and EN
60204
-
1:2006+AC:2010 norms, and to EN
