Vertical Discharge Cowl (HAN / HAF) – High-Performance Roof Exhaust Solution

The Vertical Discharge Cowl (HAN / HAF) is a robust and efficient roof terminal designed for the safe extraction of air from ventilation systems. Engineered to deliver vertical airflow discharge, it prevents contamination and protects roof surfaces, making it ideal for both residential and industrial HVAC installations.

Key Benefits

Vertical Air Discharge for Clean Exhaust
Directs air vertically upwards, helping to prevent re-entry of contaminated air and reducing impact on surrounding roof areas.
Optimised Roof Integration
Efficient design allows air intake units to be installed closer together, maximising roof space utilisation.
Weather Protection Built-In
Equipped with a wire mesh guard and internal deflector, protecting against snow ingress and ensuring effective water drainage.
Durable Construction
Standard units are manufactured from galvanised steel, with optional materials including stainless steel and aluminium for demanding environments.
Effective Drainage System
Larger models (Ø200 mm and above) include a flexible PVC drain tube to ensure efficient removal of moisture.
Flexible Connection Options
Available with male, female, double-sided, or flanged connections, allowing easy integration into different duct systems.
Wide Size Range
Covers a broad range of diameters (Ø100 mm to Ø710 mm and above), suitable for various airflow requirements.

Applications

Roof exhaust systems for HVAC
Industrial ventilation systems
Residential ventilation outlets
Air extraction in commercial buildings
