Delta's Ventilation Filter

Bagfilters from Delta Filtration: Delta Filtration's Ultra Seal Bag Filters are specifically designed for situations requiring the highest degree of air cleanliness. The Ultra Seal Bagfilter is a new and revolutionary synthetic extended surface high capacity ventilation filter. Delta Ultra Seal Bagfilters exceed the performance and health ratings of all competitive synthetic/microglass ventilation filters. The unique exclusive synthetic fibre media combined with Delta Filtration's dynamically balanced filter design affords lowest resistance, highest efficiency, greatest dust holding capacity and best value for money of any bag filters within the industry to date. On our commitments to continue the company reputation for offering the highest levels of performance expertise, quality, and after sales service in the air filtration industry, we carefully select our raw materials to ensure they conform to strict performance requirements highlighted by our company's dedicated quality control programme.Delta Ultra Seal Bagfilters provide extended surface filtration efficiency through media formed into individual dust holding pockets. These pockets are created by a multi-row space ultrasonic welding process, which promotes uniform spacing between each pocket, ensuring optimum dirty-air-to-media contact. In addition, each pocket is bonded and sealed to its own J-Channel support frame which is fastened to a heavy duty corrosion-resistant steel frame designed to prevent air bypass by eliminating metal contact points between components.Dual Stage Media:Delta Ultra Seal Bagfilters utilize a dual stage media. The first stage is a pre-filter produced from an exclusive blend of coarse denier synthetic fibres designed to arrest large particles in the air stream and enhance dirt-loading abilities. The second stage is a layer of microfine polypropylene fibres fastened to a polypropylene backing which captures the remaining smaller particles. This dual-stage three-ply configuration increases overall efficiency and dust-holding capacity for the bagfilter. The continuous filament (endless fibre) associated with the process further ensures the integrity of the product and virtually eliminates the possibility of fibre shredding. The media is made of break resistant synthetic fibres and has greater inherent strength than microglass. The media is less susceptible to handling and system damage and is not affected by moisture and humidity. In addition the synthetic fibres are more resistant to shearing stresses encountered at high airflow rates
