■ These units include G4 gravimetric fi lters standard type, which
can be replaced by:
- G4 gravimetric fi lters with low pressure drop.
- G4 gravimetric fi lters standard type + M6, F7 or F9 folded
opacimetric fi lters.
- G4 gravimetric fi lters with low pressure drop + F7 or F9 folded
opacimetric fi lters.
- Double stage of folded opacimetric fi lters (M6+F7, M6+F9,
F7+F9 or F9+F9).
■ The width of the frames is 24 mm for the G4 standard type and
48 mm for the G4 low pressure drop and all opacimetric fi lters.
Important: G4 fi lters standard type supplied from the factory
cannot be replaced by other types of filters because the
thickness of the frames is diff erent.
When the factory-selected frames combination has less than
98 mm width, the structure incorporates a tensioner to lock the
position of the frames.
To extract the frames it is necessary to loosen the screws
securing the tensioner.
Note: the fi lters cleaning procedure is explained in the chapter of
