STEEL flow SF-E-Jal Col® 150 wall conduct incl. THERMOBOX, galvanized steel, stainless steel
With the SF-E-Jal Col® 150 wall box from the COMPAIR® STEEL flow series, the exhaust air produced by island or wall bonnets can be effectively directed outside. The equipment includes the THERMOBOX heat retention system and the E-Jal Col® stainless steel external louvre with guide bodies on the blades for optimum flow guidance. The sustainable COMPAIR® STEEL flow technology features precisely calculated radii of the curved sections and air guide bodies, allowing the air to flow energy-efficiently and particularly quietly. Manufactured from galvanised steel, COMPAIR® STEEL flow is non-combustible and therefore meets all requirements for extended fire protection. In addition, the integrated THERMOBOX ensures that neither cold draughts can enter the room nor heat can escape. It has a blower door certification with a required opening pressure of 65 Pa. The premium backflow flap works without vibrations or rattling noises. The wall duct is suitable for round pipes made of aluminium, steel or plastic with a diameter of 150 mm. Its installation depth is 500 mm with the possibility of shortening to 220 mm. A wall opening of 155 mm diameter is required.

Wall conduct, incl. built-in heat retention system THERMOBOX and stainless steel external blind E-Jal Col®. Guide vanes on the slats of the blind provide for optimised flow guidance.
