Stadium BM436 152mm (6") core drill ventilator providing 161cm² free airflow area - suitable for combustion air supply to appliances up to 39.2kW net rated input. 265 × 265mm brown aluminium external grille and white aluminium internal grille. 610mm (24") tube. The 152mm tube diameter eliminates the need for the larger flat wall grilles used in high free-area applications, reducing the exposed grille area without compromising the ventilation requirement. Stadium BM436.
Key Features & Benefits
161cm² Free Airflow Area - For combustion air supply to appliances rated up to 39.2kW (133,000 BTU/h) net - the largest free area in the Stadium core drill range.
Security-Focused Design - The 152mm tube delivers a 161cm² free area through a relatively compact grille footprint - compared with a flat wall grille of equivalent free area which would require a much larger exposed opening.
265 × 265mm Aluminium Grilles - Brown aluminium external grille and white aluminium internal grille - durable and weatherproof.
152mm (6") Core Drill Tube - 610mm Length - For thicker walls typical of solid construction. Longer tube than the 350mm BM418 for solid or thicker cavity walls.
Durable Aluminium Construction - Corrosion-resistant for external applications.
Combustion air supply for solid fuel and gas appliances up to 39.2kW
