8. Component technical data.
8.1 Rotor
Desiccant Rotor (Silica Gel) chemical resistance
Attention: The following chemicals will damage the DESICCANT ROTOR
(SILICA GEL) or reduce its dehumidifying capacity.
Note : Using the below chemicals with FISAIR DFRA air dehumidifiers may
invalidate the guarantee.

ORGANIC COMPONENTS
Please note that you must also be careful when using the following volatile organic
components, which have a high boiling temperature and a low vapour pressure. Once
the silica gel absorbs these volatile components, it does not release them. This means
that silica gel will then not work to remove moisture.
