Inspection and care of filter
ROTOVEX is supplied with a class F7
supply air filter and class F5 exhaust
air filter. The filter is divided into 2
cassettes for ease of handling. The
filters are stretched with extensible-
rails against sealing strips to minimise
leakage.
The filters are disposable and should
be replaced when the pressure drop
exceeds the given limit.
The filter can be ordered from
ROTOVEX suppliers or from
Systemair.
Inspection and care of rotating
heat exchanger
ROTOVEX is fitted with a rotating heat
exchanger. The rotor is made of
aluminium.
Service and maintenance
Clean the surface of the exchanger
using a vacuum cleaner with a brush
fitting. Take great care not to damage
the surface. Inspect and clean the heat
exchanger surface when changing the
filter, at least twice a year.
Clean using the exhaust air filter
space, turning the rotor by hand to
access the whole surface. If
necessary, compressed air may be
used to remove dirt.
If the transmission belt is worn or slack
it should be replaced. Contact
Systemair Service for help.
