NOTE:
- Although the above filter casing types are standard, flnage type hepa filters & pre filters and box type fine filter can also be manufactured. In that case, their related specifications will change.
- The standard flange width for pre filters is 25 mm and that for fine filters and hepa filters is 30 mm but, flange width can also be made as per customer requirements.
- U15 - ULPA Filters and H14 - HEPA filters can also be manufactured in both deep pleat and mini pleat type. Details can be given on specific request.
- The dimensions mentioned above are outer to outer sizes flange sizes for flange type filter and outer to outer box size for box type filters.
- The details mentioned above are subject to change owing to continuous improvement in design.
