Deflector bonnet for the exhaust air with inserted bird protection grille. Diameter specification refers to the connection diameter of the deflector bonnet. The deflector bonnet has a slip-on sleeve. Note:When the exhaust air system is at a standstill, moisture, snow or dust can enter the pipe system. To prevent moisture from being sucked in with fresh air intakes, the air velocity in the free cross-section must not exceed 2 m/s.

Deflector hood (DHE), square, with duct profile galvanised – for efficient exhaust air guidance and optimal weather protectionThe Intelmann deflector hood (DHE), square, galvanised with duct profile is the ideal solution for the safe and efficient discharge of exhaust air from ventilation and air conditioning systems. Its well-thought-out design ensures targeted redirection of the airflow and reliably prevents the ingress of rain, snow and foreign objects into the duct system.Thanks to the robust construction from galvanised steel sheet, the deflector hood is particularly resistant to weather influences and is ideally suited for use on roofs and in industrial environments.Why choose a deflector hood (DHE)?✅ Effective weather protection – Prevents ingress of precipitation and protects the ventilation system✅ Optimised air guidance – Deflector ensures controlled redirection of exhaust air✅ Robust construction – Galvanised steel sheet for high durability and corrosion protection✅ Easy installation – Duct profile allows quick and secure integration into ventilation systems✅ Versatile application – Suitable for industry, commercial and residential buildingsTechnical specifications✔ Design: Square✔ Version: With duct profile✔ Material: Steel sheet, galvanised✔ Application area: Exhaust air / discharge air✔ Installation: Directly on ventilation duct or roof structureAvailable sizesThe deflector hood is available in the following dimensions:200 x 200 mm250 x 250 mm300 x 300 mm350 x 350 mm400 x 400 mm450 x 450 mm500 x 500 mm600 x 600 mm650 x 650 mm700 x 700 mm800 x 800 mm900 x 900 mm1000 x 1000 mm1100 x 1100 mm1200 x 1200 mm1300 x 1300 mm1400 x 1400 mm1500 x 1500 mmAreas of applicationIndustrial and commercial buildings – Reliable exhaust air guidance on roofsVentilation & air conditioning systems – Protection and efficiency enhancementTechnical building equipment (TBE) – Professional solution for exhaust air systemsResidential buildings – Use in larger central ventilation systemsNote: For optimal function, the deflector hood should be selected to match the duct size and installed professionally.
