Email Air Handling Inter-firm filters are high performance dry-type filters, intended for use in semi-critical locations, in both HVAC and general industrial. The Inter-firm is available in three efficiencies to suit a range of applications. With its’ rigid construction, the Inter-Firm ideally meets the design requirements of today’s variable air volume systems.
Performance is not interrupted by changes in air velocity nor fan shutdown and configuration is not affected by accumulated dust. The Inter-firm filters have the lowest pressure drop available for their type and design.
Continually low resistance under varied air volumes ensures power savings over the life of the filter.
Inter-firm is available in ratings F6 (60/80%), F7 (80/90%) and F8 (90/95%). The
media is colour coded for easy identification of efficiency.
The final pleated filter is extremely durable with high compressive strength in the airflow direction. This durability also ensures that there is no damage to the pleats during transportation and storage.
The lofted media and tapered radial pleats provide a high dust holding capability, extending the life of the filter. A continuous sheet of special fibre filter medium is pleated into a vee configuration with finger type separators inserted between the pleats. This forms the filter element which is bonded into a rigid corrosion-resistant steel frame with all joints encapsulated and sealed in a special urethane. As a result the system will require less down time and in turn reduce maintenance costs.
When tested to AS1324.2 the filter shall achieve a No 1 dust efficiency of 60% (F6), 80% (F7) or 90% (F8). A NATA test certificate will need to be provided which will be less than three years old to conform to this specification.
