ESAM side-channel blowers / aspirators are built with die-cast aluminium alloy, wherever it is possible. This ensures high performance, reduces production costs, increases output and fosters quality uniformity.

Motors are built according to regulations CEI 60034-1 (03-2011), protection IP 55, insulation CL F.

Functioning of side-channel blowers / aspirators is based on the principle of the outflow of fluid, by means of spiral movements created by the centrifugal force of the special impeller in a peripheral toroidal channel.
