Ball diffuser rails with swivelling ball jets. Adjustment range
of discharge direction 360° on all sides.
Consequently, they may be set to blow in small single jets
or in one compact air jet. Air jet control along ceiling or in a
room.
Also suitable for installation in a ceiling recess with offset
ball arrangement. Air discharge suitable for variable air
quantities of 100 to 25%.
Air diffuser consisting of swivelling ball jets made of
synthetic material, which are held aluminium profiles by
means of a clamping device. Setting of balls according to
customer’s instructions, pre-set at works. Connection box
(with/without insulation) with round tube connection and
integrated fixed resistance FW0066 including 4 aluminium
brackets of galvanised metal sheet. Visible areas with matt
lacquered finish according to RAL 9010, 25% brilliance.
