LCT20 – It’s so discrete you won’t realise it’s there.

Waterloo believe that to offer our customer what they require, service (although important) is not enough.

We understand that must be at the forefront of technology and technological advancements.

As such we present to you our latest addition to our Square Diffuser range:


The NEW Lay-On Ceiling Tile diffuser


The LCT20 has been developed for use when mounted directly on top of a 20% Open Area ceiling tile (supplied by others).

The diffuser utilises low discharge velocities to ensure that predominantly horizontal diffusion takes place over a defined flow range.

Supplied in black (RAL9005) as standard for an undetectable effect, the diffuser sits unobtrusively behind ceiling tiles to provide efficient air distribution without compromising the projects décor.

Fixings and Fittings

For fitting, the LCT20 can be retained using either

  • Two sided adhesive tape

The LCT20 can be mounted via either

  • Plenum mounting – side entry plenum box

As an extra, a quieter option is available
