Range Hood MAD200 Roof Cowl Round Down Discharge
VRV roof cowls are designed to provide vertical discharge exhaust for mechanical ventilation systems. Butterfly type dampers prevent rain water entry when the system is not operating. VRV models are designed for circular, flange connection applications.
Construction
The range is manufactured from galvanised steel and aluminium.
Features
Can be mounted at angles of up to 30°
Durable construction
Smoke spill compatible
Available in optional Colorbond™ colours.
Application Notes
Vertical discharge cowls should only be used where exhaust air velocities are sufficient to prevent rain ingress during operation. For low air velocity applications refer to VCQ horizontal discharge cowls. In high wind speed locations, the use of magnetic catches is highly recommended.
