Description
The TM-2 and TM-4 ducted modules are lightweight, disposable HEPA filter ceiling modules. Both are designed for optimum filter performance in cleanrooms with individually ducted modules.
The TM-2 is a commercial, cost-efficient filtration module for Class 100,000 to Class 10 cleanrooms. lt is ideally suited for electronics, healthcare, food processing industries, or other applications where clean air quality is a priority.
The TM-4 ¡s a superior air filtration module designed for Class 100 to Class 1 cleanrooms that demand higher efficiency. TM-4 modules are also suitable for applications requiring lower pressure drop than conventional ducted modules.
All standard TM-2 and TM-4 modules come with either a 10″ or 12″ diameter ¡nlet (with special size inlets available). Both have an adjustable distribution plate, which can be adjusted with a screwdriver from the room side through an access port located in the center divider of the module. An optional design with a fixed perforated distribution plate is also available (center divider with access port not included).
All standard modules come with an integral expanded metal painted face grille. A contractor grade of both models is available with the same options.
Sturdy, Lightweight Housing
Both the TM-2 and TM-4 modules come in a variety of sizes, offering flexibility for any installation. The TM-2 24″ x 24″ module weighs 14 pounds and the 24″ x 48″ size weighs 24 pounds. The TM-4 weighs 26 pounds and 42 pounds, respectively. The two larger sized modules weigh substantially less than competitive units.
With the AAF TM-2 and TM-4 modules, the possibility of bypass leakage ¡is virtually eliminated. All metal to metal joints are bonded to prevent leakage. Plus, each unit is entirely factory-sealed, so there are no leak paths between the filter inlet and air leaving side.
One room side air sampling port allows for checking of static pressure or contamination levels of the air entering the module. The same port is also used to adjust the damper-diffuser. Housings are available with four suspension points for attachment of hangers.
AstroCel II LPD Series Mini-Pleat Filter Optimizes Capture, Minimizes Resistance, and Reduces Costs
The media in each AstroCel* |! LPD Series Filter is made of glass microfibers formed into a .015″ thick mat pleated to allow a large amount of media surface area to be incorporated within the housing. The pleats are spaced with narrow ribbons of filter media, allowing the air to flow through the filter pack with minimum resistance. These ribbons make it possible to have a high performance media pack from 2″ to 4″ deep. The pack ¡s sealed inside the housing on all four sides with a white urethane sealant that eliminates voids and leakage.
The airflow, initial resistance, and service life of the 2″ mini-pleat media pack will out-perform conventional 6″ HEPA filters made with corrugated aluminum, nearly two to one.

The AAF TM-2 series, with ¡ts mini-pleat pack, is a commercial, cost-efficient performer that delivers peak filtration in unidirectional and nondirectional-fow cleanrooms from Class 100,000 to Class 10. Its lightweight, disposable design, ease of installation, and efficiency options make it ideal for applications where it is important to regulate the quality of air.
TM-4 Features
- Low Resistance, High Airflow
- Low Profile Housing (7″ Gasket, 7 3/4″ Gel)
- Choice of Filter Pack Depth (2 1/2″, 3″, 3 1/2, 4″)
- Gasket or Gel Seal Installation Options
- Contractor Grade Available (TM-4-CG)
The AAF TM4 series, with its deep-pleat pack, was developed to meet industry requirements for large cleanrooms with individually ducted modules. This superior efficiency module reduces operating energy costs without compromising the demand for optimum filter performance. The TM-4 ¡s available with custom efficiencies ranging up to 99,999995% on .10 to .20 micrometer size particles, making it ideal for Class 1 Waferfabs.
