Check the performance, electrical, sound and dimensional information in the technical document before ordering. If you are replacing an existing fan, match the complete product code and electrical supply.
Choosing the correct QUBE SQU fan
Confirm the required airflow and system resistance before selecting a fan. The duct connection, phase, motor type and any terminal-box or spigot suffix must also match the installation. A similar-looking model code can represent a different electrical supply or connection arrangement, so use the full code SQU82/500-EC-3 when comparing the fan with a schedule, drawing or existing unit.
