Underfloor Air Distribution

TROX Floor diffusers installed in raised access floors combine the advantages of mixed air flow with the advantages of displacement air flow.

TROX is the world leader in underfloor air distribution and, as such, understands and designs around the differences between pressurized floor cavity supply and the ducted delivery typically employed by overhead air distribution systems.
