ABSTRACT:
A modular frame arrangement suspendable from the ceiling of a room is proposed for receiving filters having fluid seals for clean room ceilings, which consists of structural rails having U-section channels for receiving the fluid, the rails being provided with a central web. Lying parallel to the ceiling, the webs of the rails and the central webs are constructed as hollow sections, the hollow section of the web being formed of two hollow chambers and a T-section groove lying between these hollow chambers. For connection of the rails, connection members are provided which have a square central part and integral arms offset in height at the lower side. The connection members are inserted with their arms in the rails so that the respective U-section channels are extended around the corner.
