FILTER ELEMENTS

TECNOCOMP self cleaning air filters for gas turbines provide an effective barrier against dust and other contaminants, assuring high efficency air filtration in the most severe conditions and environements.

STRUCTURAL FEATURES

Circular expanded rubber gasket with triangular or rectangular section glued on the bottom cover of the cartridge. Hardness: 60 shore. Material: neoprene foam with nytrogen cells (or equal).

Upper and bottom covers: galvanized steel 6/10 or painted steel 6/10 with epoxy paint; 304 stainless steel on request. Steel covers are glued to the pleated media by a high temperature resistant resin; in particular, this adhesive is stable against the action of chemical agents.

Inner and outer liners: galvanized steel 5/10, perforation Ø 6,5 m/m. Assembly: seam folding with at least 1 perforation stroke. On request, epoxy painted steel or 304 stainless steel.

Filering media: pleated media composed by resin impregnated cellulose, cellulose mixed to synthetic fibres.The advantages of this special paper are: easier and better cleaning, higher air flow efficency, lower energy costs compared to other conventional cellulose media .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.

TECHNICAL INFORMATIONS

MECHANICAL TREATMENT: Due to the shape and the small volume of the filter element, filter media must be mechanically shaped. This process consists in a corrugation in the length and an alternate folding in the width of the filter media. After this treatment, the obtained cylinder media is placed into the liners and the caps. A special glue fixes all parts together and guarantees the air tightness of the system. The pitch of the folding is reinforced by seven annular beads of hot-melt glue. This construction feature prevents the excessive movement of the media caused by the swelling of the cellulose fibres during humid conditions and it maintains an even pleat spacing thereby ensuring the most effective usage of the available media surface area.

QUALITY CONTROL: Filter media are rigorously tested by outer lanboratories highly qualified and specialised in air filter field, such as Air Filter Testing Laboratories (Kentuky, USA) and M & E Testing Laboratories (England) in order to check efficiency, dust holding capacity, thickness, grammage, volatile components content, burst strength, tranction resistence, etc. Filter elements are tested accordingly to ARAMCO testing procedures and they are certified so to respect the following features:

• efficency: > 99,95%
• pressure drop: <= 10kPa
