COMPAIR FLOW FLAP NON-RETURN TRIPLE ROUND 125MM 4022049

THERMOBOX 125, black/silver

The COMPAIR® flow THERMOBOX 125 heat retention system can be easily retrofitted into Naber® wall penetrations. Vertical installation is also possible when the exhaust system leads freely through the roof.

From a technological perspective, the heat retention system impresses with innovative solutions. In addition to the thermally insulated cover of the outer pair of flaps, it also includes a magnetic closing mechanism with almost silent operation. The back flap, certified to the Blower-Door standard, opens completely even at low air flow, ensuring reliable steam exhaust to the outside.

When the flap is closed, two completely insulated air chambers are created, effectively preventing energy loss. Installation into an existing exhaust pipe is very simple.

The THERMOBOX heat retention system for retrofitting into existing Naber® wall penetrations and suitable for vertical installation (exhaust of exhaust air through the roof).

— Certified to the Blower-Door standard (required opening pressure %mygt% 65 Pa).
