Rigid Cell Filters

Rigid Cell Filters, also known as Turbine Filters, are designed to meet exact specifications in medium to high-efficiency commercial or industrial applications. These Rigid Cell Filters are used in a variety of applications including hospitals, manufacturing plants, microelectronic component assembly and food processing. They are ideal for variable air volume (VAV) systems where changes in airflow can have adverse effects on non-rigid type filters.

The key to ISC’s filters performance is the design. It is built around controlled filter media spacing which ensures amaximum airflow with minimal resistance factors.  As we know, the heart of any filter product is the media. The filter media is a high density, fiberglass or synthetic fiber, which consistently provides high-performance ratings. These Turbine Filters provide excellent dust holding capacity and coupled with its rigid construction virtually eliminates dust particle unloading downstream of the filter.

The Z-Pak's total rigid construction makes it ideal for variable air volume systems (VAV), where changes in airflow can have an adverse effect on non-rigid type filters. Available in a variety of filter dimensions and efficiency ratings. The filter media pack is constructed by pleating a continuous sheet of media into uniform spaced pleats, which are then separated by flame retardant and injection molded plastic media separators.
