Traditionally fans filter units sit on a cleanroom grid ceiling designed to take the load imposed and provide a seal to the ceiling. Where a suitable grid does not exist, it is necessary to install an adapter frame which meets the dimensional requirements of the fan and the opening provided in the ceiling, if it is commercial ceiling grid, spring tee or solid cut out there is a frame to suit with support mechanisms from the ceiling or soffit.
