RAX – Semi-circular supply air diffuser with adjustable nozzles
Adjust the near zone from the outside
RAX is a semi-circular low velocity air diffuser with adjustable nozzles accessible from the outside of the diffuser, providing a flexible and adjustable near zone. The diffuser ensures high induction of room air, which reduces the temperature gradient in the occupied zone and results in a higher floor temperature. RAX is particularly well-suited for offices, conference rooms, and other environments where consistent comfort is important.
