The Barco R9802353 UDX Bottom Filter is an optional filter for the Barco UDX series projectors when installed without a rigging frame. This will help protect the LDM devices in dusty environments.
It is compatible with the UDX-4K22, UDX-4K26, UDX-4K32, UDX-4K40 FLEX, UDX-U32, UDX-U40, UDX-U45LC, UDX-W22, UDX-W26, UDX-W32, and UDX-W40 FLEX model projectors. For models mounted in rigging frame, use kit number R9802352 instead.
