MAINTENANCE

9.3.4 Panel filter and control box filter replacement

➢ The ventilation fan of your compressor needs high amount of free air. The operation of this filter
causes the compressor to take in the dust of working environment. Depending on the degree of
dustiness in the operating space, the panel filter may be rapidly clogged.
➢ When the panel filter is clogged, the aid intake is reduced, resulting in increase of the compressor
operating temperature. Furthermore, as the intake speed would reduce with the filter clogging, it
would be harder for the dust particles to pass through the filter.
➢ Frequently clean the panel filter. For this purpose, remove the filter cover sheet by loosening the
corner bolts, and apply compressed air at the back of the filter (outwards). When the dust on filter is
removed, you can use the filter again. The panel filter is characteristically oily to
some extent. If you fail to clean it for long times, this oil is hardened, which makes the cleaning
impossible. In such cases, replace the filter.
To replace the panel filter;
•
Stop the compressor. Remove the bolt at the top of the perforated pouch holding the filter, and
take the perforated pouch out.
•
Replace the new filter, and screw the perforated pouch in place.
To replace control box filter;
•
Open the louver grilles of the inlet filter (Fig. 22).
•
Remove the filter element.
•
Insert the new filter element into the louver grille. Ensure that the smooth side of the filter elemet
faces the air inlet side.
•
Place the louver grille back onto the filter housing.
