Oil-free flow

The rotating shaft is retained by two bearings mounted outboard, so there's no contact between rotating and static parts inside the blower (except the shaft seals).

The graphite shaft seals separate the air and gas flow from the bearing housing area. The bearing housings are arranged in a way that there's an area open to the atmosphere between the sealing and the bearings. This area is designed to cool the shaft.

This means, that no grease (in the case of smaller blowers) or lubrication oil (in case of bigger blowers) can infiltrate into the blowers casing.
