FILTER ELEMENTS
TECNOCOMP industrial filter elements are particulary suitable for the separation and the collection of dry powders. The filtration operates from the outside to the inside of the filtering surface, ensuring the entire flow of the air. The removal of separated powders is obtained by a spout of compressed air through a "Venturi" or a turning cleaning device, which drives the air from the inside to the outside. Moreover, unlike pocket filters, cylindrical ones with pleated filter media, (paper, polyester, polypropilene) offer the advantage of a big working surface with a structural reduced volume.
A COMPLETE LINE FOR A WIDE RANGE OF APPLICATIONS
TECNOCOMP dust collection filter elements are project for many applications, ensuring the observance of emission values for environment defence, a high protection of work places as well as the opportunity to recover the product in:
- epoxy powder painting plants
- sanding equipments
- grinding equipments
- welding fumes suction plants
- lead fumes suction plants
- cement factories
- coal working plants
- pharmaceutical and chemical workings plants
- gold workings plants
- general dry workings installations
- plastic material workings installations
TECNICAL DATA
- Working temperature: from +5 up to +140° C special versions up to +180° C.
- Separating efficency: according to BIA trials (GERMAN INSTITUTE OF PROFESSIONAL ASSOCIATION FOR SAFETY ON WORK) with aerosol test 3 (quartz powder) the medium value of passage is 0,05%.
- Cleaning of elements: counter-current compressed air at 4 ÷ 6 bar.
STRUCTURAL FEATURES
- Expanded rubber gasket 15% shore
- Upper and bottom
cover: galvanized steel 6/10 or painted steel 6/10 with epoxy paint;
aluminium die-casted flange fast connector: the simple fixing of the
aluminium flange allows the assembly of the element both from the inside
and from the top of the filter in few seconds; compact synthetic resins.
Steel covers, as well as flange, are glued to the pleated media by a very resistant resin at high temperatures; in particular, this adhesive is stable to the action of chemical agents.
- Inner liner in galvanized steel 5/10, hole Ø 6,5 m/m, or in expanded steel 6/10.
- Filering media: pleated media composed by resin impregnated cellulose, cellulose mixed to synthetic fibres, polyester, anti static and metalized polyester.
- The special pleating system guarantees the stability of the structure, by mantaining its original shape for longtime, without loosing working filter area, with relevant consequences on the efficiency and life of filter elements, without adding any particular spacer.
- Spacing bands: for cartridges whose height is more than 600 m/m, few spacing bands are applied by a special adhesive both in order to guarantee that pleats do not touch each other (as a consequence, filtering surface will stay totally efficient) and to allow catridges to be stronger during cleaning operations.
On request, Tecnocomp is willing to manufacture filters with special dimensions, filter media and junctions.
