The AVAC LU 21 CF provides a constantly comfortable environment and is designed to fit through a standard loft hatch into a roof space and needs no external condensing unit. The only visible part of the system are two small ceiling grilles, one through which cooled, filtered air is quietly delivered into the room and one for return air. All functions are programmed using the handy remote control unit. The AVAC LU 21 CF is a highly affordable solution for bedrooms, home offices, bungalows or any area with a roof-void or suitable space.
