Gordon Cleanroom products model LG-15 is a 1-1/2″ face ceiling grid designed to meet the exacting standards of light to intermediate duty cleanroom applications. Grid members are fabricated of extruded aluminum for maximum structural integrity and corrosion resistance, even in harsh environments. Aluminum assembly clips simplify installation and require no special tools to attach grid components. Factory-applied gaskets provide an airtight seal between cleanroom and interstitial spaces when compressed by the weight of filter modules, light fixtures and blank panels. LG cleanroom grids are also available in 15/16″ (LG-10) and 2″ (LG-20) face widths.

Optional hold-down clips are available to secure blank panels in the grid.

NOTE: Gordon does not recommend grid systems for use with fan powered modules (FFU’s). Consider Gordon rod-suspended grid systems for FFU applications.
