When wiring the Axial roof fan to add overload protection switch, and use in order to avoid burning motor rated full load current. Scope 3. Axial roof fan continuous operation, refer to the static pressure curve, and used within the scope of the curve, but as close to high-voltage Do not exceed the scope, it must be close to closing pressure if used, the best in the pipeline set the pressure relief valve, when the line closed, the pressure relief valve will open access to ensure the life of the conditioned air blower.
