About these specifications

Values and performance curves are supplied in the product catalogue. They are not independent BROSNGAN test results. Airflow and maximum static pressure are separate catalogue ratings, not a simultaneous duty point. Noise test conditions and measurement distance are not provided. Confirm the exact voltage, configuration, dimensions and applicable test reports before ordering.

How do I match CM Louvered Ventilation Grilles to a fan?

Compare the 7 listed accessory configurations with the actual fan and panel drawing. Check the catalogue reference, hole centres, cutout, depth and blade clearance. A nominal size code does not guarantee fit.

What evidence should I request before specifying this accessory?

Request the current mounting drawing, material details and supplied components. For filters and grilles, confirm airflow resistance; any filtration or ingress claim needs configuration-specific test evidence. Material, filter inclusion, open area, ingress rating and compatible fan assemblies require confirmation.

How do I request the correct configuration?

Quote CM Louvered Ventilation Grilles and the configuration reference from the table. Include your fan reference, panel drawing, mounting requirements and quantity. BROSNGAN CM references are catalogue selection references; the supplied model label, availability and price are confirmed on enquiry.
