3 IN-LINE MICRONIC FILTERS M39-00 (00mm element) M39-300A (300mm element) M39-450A (450mm element) GENERAL DESCRIPTION The Drum International range of Micronic Filters are supplied in three basic sizes to suit various applications when discharging bulk foodstuff. The filters cover a performance range of 00m 3 3 /hr to 000m /hr, with the filter element being rated at 5 micron, (Refer page 3 for further details of dimensions and performance figures). Both the Filter bowl and element are of stainless steel construction thus making the cleaning and maintenance of these items a quick and simple operation. A sightglass is built into the filter bowl wall to allow visual inspection of the filter element, additionally, a coloured indicator is located on the filter body to give warning of the element s condition. The two larger filter assemblies feature industry standard TW flanges allowing easy fitment into compressor air systems (September 03) Page 3

4 GENERAL DIMENSIONS AND PERFORMANCE FIGURES The DRUM range of Micronic filter assemblies are supplied in three basic models to suit various applications and are classed by the overall length of the filter element. The element sizes are 00, 300, and 450mm. (Refer Figs,, and 3 for dimensions and performance data.) Alternative hole J00 flange square 4 holes x dia equi-spaced on 80 P.C.D.

Filter fitted with 450mm Element 0mm Req d to remove bowl. OPERATION OF THE RESTRICTION INDICATOR An indicator is built into the filter assembly and is activated by a pressure difference within the filter as the element becomes restricted. The indicator window normally displays a green sleeve when the element is functioning correctly but as the filter becomes contaminated, the green sleeve will move upwards allowing the red indicator sleeve to come into view. The indicator will show fully red when the pressure difference reaches 00 mbar. It is recommended that the filter element is cleaned as soon as the red sleeve appears, as a drop in air delivery pressure will occur. (Refer Fig. 4) Indicator window showing fully green.

It is recommended that the filter element be ultrasonically cleaned, if you do not have acces to such equipment please follow the procedure outlined below 5. Immerse the filter element into a suitable receptacle filled with hot soapy water / commercial detergent and remove any contaminants by agitating and rotating the element 5.3 When the element has been cleaned it is advisable to repeat the process in clean water and thoroughly rinse until all traces of detergent have been removed. By using a high pressure water jet or steam pressure lance working from the inside outwards, the same effect can be achieved. The element should be dried, preferably using a compressed air line again blowing from the inside outwards. 5.4 Visually inspect the element after cleaning for any remaining contaminants and repeat the cleaning procedure if necessary. The filter element should also be checked for any damage to the pleated media, if in doubt DO NOT use and replace with a new unit./.
