a-CXW 0402 - 1204
The 4-way a-CXW cassette has been developed to provide excellent performance in terms of efficiency, silent operation, and control flexibility. The a-CXW range features a 3-speed AC motor and it is available in 7 sizes for installation in 2 or 4-pipe systems. The 2-pipe version can be equipped with an integrated electrical heater. Thanks to the elegant design of the air diffuser and the wide range of controls for single or multiple connections, the a-CXW cassettes are suitable for all kinds of installations.
