Combi+ Pure 315 mm. - 10 m.

Avoid condensation. Aluminum duct on the inside and plastic duct on the outside. For air extraction or intake. Combi + is an aluminum duct covered with a layer of plastic to prevent condensation that occurs on the ducting of our indoor grow extraction system. If the air circulating through the duct is cold, it also cools the aluminum duct, which causes moisture to condense on it and even drip. To avoid this situation, the plastic coating of Combi + acts as an insulator against this condensation.
