Rittal’s new TopTherm fan-and-filter
units are said to bring tangible benefits.

Eliminating the need for tools,
simplification of key installation, service
and maintenance tasks will all save time.

Mounting on the enclosure,
electrical connection, removal and
refitting of the fan with the airflow in
either direction, and removal and
replacement of the filter mat may all
be carried out without using tools.

Diagonal fan technology provides
improved performance against
increased static pressure difference
which, in turn, offers greater energy
efficiency and a more constant air
throughput, effectively minimising
occurrence of hot spots.

The switch has been made as
simple as possible due to global
compatibility with the existing fanand-
filter unit range.
