Specification text

Particulate filter air terminal device type TFC for ceiling installation as final filter stage and for air distribution. Fitting of filter elements for the separation of suspended particles such as

aerosols, toxic dusts, viruses and bacteria from the supply or extract air. Casing with side entry or top entry circular spigot or with side entry rectangular spigot. As standard, ceiling mounted

particulate filters with circular spigots are fitted with a lip seal. Choice of different constructions: low-leakage ('air-tight') shut-off damper, either manually adjustable or with electric actuator;

volume flow limiter; damper blade for volume flow rate balancing; recessed side entry spigot; or aerosol feed. Casing without test groove for filters with flat seal, continuous foam seal or gel seal;

casing with test groove as an option for filters with flat seal. Filter depths from 78 to 150 mm. Sheet steel casing with RAL 9010 powder coating; stainless steel as an option. Casing and diffuser

are suitable for installation into commercially available plasterboard and mineral fibre ceilings as well as in walk-on ceiling systems. Installation into clip-in tile ceilings is also possible (optional). External diffuser as standard, internal diffuser as an option for flush installation. Fixing on the cross bar with central screw and spring; can be removed so that the filter

(downstream side) can be checked. The filter elements are pressed into place by an installation subframe with four clamping screws. As standard, the casings are fitted with an internal

measuring tube and pressure measurement points for monitoring the differential operating pressure. As standard, the pressure measurement points are at the top, optionally at the side; in case

of false ceiling installation the measurement points are at the top. For the fitting of Mini Pleat filer panels with flat seal, continuous foam seal or gel seal. Leakage test for each casing. Leakage

class L1 to EN 1886; leakage class D to EN 15727.
