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.
