Aerovent IM-220 - Manual

Standard Shaft Seal
A Viton shaft seal can be added to the housing as an option
and should be specified when the fan is used for handling
dirty, wet or corrosive air. This seal is suitable for operation
up to 300°F. It should also be noted that this seal minimizes
leakage; it does not make the installation gas tight.
