Ideal for Pharmaceutical and Biotech Applications
The AAF Flanders ESD Model 22 is an ideal terminal filter hood for pharmaceutical and biotech cleanrooms, or wherever hoods are regularly validated for performance and leak-free operation. They may be installed in a variety of ceiling types, including tee-bar ceilings, gel-seal grid systems, and plaster ceilings. Ideally suited for Class 100 “spot” applications, they may also be used to create Class 10,000 to Class 100,000 areas by locating the appropriate number of units in the ceiling. Units may also be installed for 100% ceiling coverage to achieve cleanliness levels to Class 10.
Gel Seal Design Ensures the Integrity of the Filter Seal
The ESD Model 22 hood features a gel-seal design that offers superior protection against bypass leakage. Invented by AAF Flanders to overcome the leakage problems associated with gasket filter seals, the gel-seal interface ensures a positive seal between the replaceable HEPA/ULPA filter and the hood. Its effectiveness has been proved in thousands of applications.
Convenient Roomside Access and Service
The ESD Model 22 hood design allows access to the filters from roomside, without disturbance to installed housing. Bottom-loading filters make roomside filter changeout quick and easy. Damper controls and test ports are also easily accessed from roomside by simply removing the protective grille.
