COSHH Regulations
The components of filters are inherently safe, but
changing air filters could expose operators to a
‘nuisance dust’ hazard. We would recommend
that
filter
changing
be
carried
out
by
maintenance personnel wearing simple dust
masks, eye protection, overalls or protective
clothing and gloves. Dirty filters should be sealed
into plastic bags for disposal.
Disposable filters
These are supplied in the forms of panel filters
and are fitted into steel channel runners. Filters
are simply withdrawn through the access door by
sliding the filter along the channel runner. Filters
should generally be replaced when the pressure
drop increases to (125pa) above the initial level.
Note: When replacing all filters ensure filter is
facing correct direction as indicated by the
airflow arrow.
