Continuous glass fiber with increasing density starting from the upstream side. Used as prelimina general ventilation systems such as air conditioning equipment, gas turbine compressor.
Media
The filter medium is constructed from selected high performance fibers in a progressive density multi-layering technique to ensure high depth loading with optimal lowest pressure-drop performance. This results in long filter life and usage, high fractional efficiency combined with relatively high dust loading and low energy and maintenace costs. The gravimetric pocket liters are 100% synthetic, corrosion-free and humidity-resistant product. It conforms to all European Union and U.S fire classifications (e.g DIN 53438 F-1 and UL-2). The pocket medium is inherently rigid, with a welded rib construction to form a pocket with the highest possible functional security in even the most brutal air-pressure and high dust-laden environments. The leak-free construction, the incorporated aerodynamic spacers and the embedded medium in a form-stable rein-forced plastic fromt-header guarantee highest per-formance in most environments -Constant quality is assured by independent quality control according to EN-779 and the individual DIN CONTROL registration number, which is printed on each unit.<br>
Synthetic fibre based filtermats. The filter media are constructed from selected high performance, non-breakable fibres in a progressive density multilayering technology to ensure high depth loading with optimal lowest pressure drop performance. While achieving gravimetric arrestance and efficiency level in accordance with EN 779 standard rating.
Laminated media is ideally suited for the production of pleated filters. The media is laminated with expanded metal for structural support. The metal is hot dip galvanized for prevention against rust damage. This layer of expanded metal is attached to the downstream side of the media. The laminated rolls are available efficiency from 35% to 55%.
