TM-4 Ceiling Filter Modules


The AAF TM-4 series was developed to meet industry requirements for large cleanrooms with individually ducted modules. The TM-4 features our AstroCel II Mini-pleat Filter Pack, which provides HEPA efficiency, a high ratio of media surface to pack depth, and reduced operating pressure drop. The modules are available with custom efficiencies ranging up to 99.99995% on .10 μm to .20 μm size particles, making it ideal for ISO Class 3 Waferfabs.

TM-4 modules come in a variety of sizes, offering flexibility for any installation. All standard modules come with a 10” or 12” diameter inlet, adjustable distribution plate, and an integral expanded metal grille. A contractor grade is available with the same options. Each unit is entirely factory-sealed, with all metal to metal joints bonded to prevent leakage.

The low profile housing and light weight of the TM-4 modules make for easy installation. The modules are typically installed in a 1-1⁄2” or 2” T-bar ceiling grid, or 2” wide gel or gasket seal, heavy duty ceiling grids, suspended from the building structure. Housings with four suspension points for attachment of hangers are standard for gasket seal applications.
