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 gas turbines 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.
Gas turbines 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.
