Inter-Firm

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. 

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. Additionally, they 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. 

Efficiencies

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. 

Durability

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.
