Low-Risk Filter Testing and Maintenance
The AAF International PharmaGel is a high-performance HEPA module with simplified filter cartridge maintenance. Equipped with four support retainers, cartridges can be tested and replaced without disturbing the module housing. A gel sealant pocket ensures airtight integrity at the filter-to-module seal.
The PharmaGel is ideally used for critical process industries like pharmaceutical manufacturing, where quick and easy HEPA filter replacement is required. Optional aerosol dispersion tubes allow for easy integrity testing of both the filter and the module. An upstream port is standard and allows the user to measure the HEPA filter pressure drop, or to sample upstream aerosol concentration for in situ filter testing.
The PharmaGel module includes an AAF AstroCel® II LPD 2 7/8" minipleat HEPA filter with a 2" media pack that provides 99.99% minimum efficiency. A laser-tested ULPA filter providing 99.9995% efficiency at 0.12µm is also available. All AAF Astrocel II filters are scanned for pinhole leaks before shipping to ensure trouble-free installation. AstroCel II 3" and 4" filters are also available for extra-depth housings.
In addition to the microglass HEPA/ULPA options listed above, AAF also offers a high-performance line of HEPA/ULPA filters that utilize extremely low pressure drop ePTFE media. This line of filtration can also be utilized in the PharmaGel module as an optional upgrade.
Robust Leak-Free Construction
PharmaGel housing is constructed of sturdy, welded aluminum with a flush-mounted, stainless steel grill. The airtight housing includes an integral aluminum flange on the downstream side, for use with a conventional T-bar grid system. The round top inlet is designed with a butterfly damper conveniently operated from the downstream side, using a rotary-type mechanism. A perforated diffuser plate beneath the damper promotes even distribution of air across the filter.
1 ½” wide stainless steel plaster trim is available for mounting the PharmaGel in a hard ceiling. 5/8” wide trim is also available for mounting the PharmaGel in inverted grid T-grid systems.
Hanging tabs are available for use of the PharmaGel in seismic active areas. Hanging tabs are welded to the body of the PharmaGel to eliminate any leak paths caused by mechanical fasteners.
