Ceiling Panel Clips

Torsion-spring clips fit over ceiling grid joists, with retaining arms that push snugly against ceiling panels to hold them in place, even when the room operates under positive pressure. Standard-sized clips (either 3-inch or 6-inch) are available that fit over ceiling joists. Clips are also designed to secure panels on either one or both sides of the joist, in case of an FFU in the neighboring bay. Convenient kits containing both types of retaining-arm clips (single- and double-sided) can be ordered.

Ceiling Module Cover

Ceiling module cover 2’ x 4’ shown, clipped to ceiling grid
(model #6705-37).

Protect fan/filter units (FFUs) and light fixtures from exposure to chemicals and water during cleanroom wash-downs. Electrical components and filters may be damaged from contact with fluids. By using ceiling module covers, cleanroom personnel save the time and effort of module removal and re-installation, which may include re-certification testing if the room is breached.

Installation of ceiling module covers requires a ladder; the covers attach to the ceiling grid with rotating aluminum clips. Three sizes are available to accommodate standard FFU sizes: 2’ x 2’, 2’ x 3’ and 2’ x 4’. Light panels would be paired-up with 2’ x 4’ covers.

Covers are made of white polypropylene with aluminum grips for convenient handling. Polypropylene resists damage from many common sterilizing chemicals. Panels are easy to store and wipe-down.
