E-Jal 150 wall conduct incl. THERMOBOX, white, stainless steel
The COMPAIR® flow E-Jal 150 wall box with integrated THERMOBOX significantly improves the room climate in conjunction with an extractor bonnet. It reliably guides the exhaust air out via the air duct. At the same time, the system prevents heat loss in the room and the penetration of cold outside air. Thus, the wall box is equipped with a telescopic tube containing the THERMOBOX, a built-in heat retention system. In combination with the E-Jal stainless steel external louvre, this results in high energy efficiency with up to 20 times less heat loss compared to standard backflow flaps. Neither vibrations nor rattling noises are generated. The THERMOBOX, which opens at 65 Pa, features Blower Door certification. The wall box including THERMOBOX thus makes an effective contribution to energy saving. The wall box is connected to a round pipe via a hose/pipe connection piece with a diameter of 150 mm. The installation depth of the wall box varies from 350 to 500 mm, whereby the pipe can be shortened to 255 mm - so the duct is suitable for different wall thicknesses. A wall opening with a diameter of approx. 155 mm is required for installation.
