Side channel blowers

A Side Channel Blower is a device used to move air and increase pressure thanks to a rotating impeller within a toroidal channel, so there is a progressive increase of energy. This side channel blowers can be used in compression and vacuum systems.

The term "side channel" comes from the peripheral position of the toroidal channel compared to the impeller shaft. A Side Channel Blower can cover a wide range of flow/pressure combinations. The maximum flow rate that can be treated is 2400 m³/h while the relative pressure range goes from -450 mbar (vacuum) to +650 mbar (pressure).Thanks to the blower’s modular features, this performance is achieved by combining the blower in different settings:

MS: two channels arranged parallel to each other
MD: two channels arranged sequentially
TS: two MS blowers arranged parallel to each other
TD: two MS blowers arranged sequentially

The acronyms MS and MD mean that the blower has one impeller (M – mono) and the compression is obtained through one (S - single)or two (D - double) transitions via the base module (single channel).

The acronyms TS and TD mean that the blower has two impellers (T – twin) and the compression is obtained through a (S - single) or two (D - double) transitions via the base module (MS).
