    Design Features: Designed to provide variable airflow for low NOx and CO emissions in high efficiency gas-fired combustion systems. Built with non-sparking materials. Blower housing assembly constructed of die cast aluminum. Impeller constructed from hardened aluminum. Rubber isolation mounts built into the blower construction to dampen vibration within the motor. Two piece blower housing assembly sealed with O-ring gasket fro combustion applications. Customer is responsible to check for any leakage once the blower is installed in the final application. Intake and exhaust tubes, all cooling ducts and vents must not be obstructed. Intake and exhaust must be free of grease, oil and foreign particles. Blower to be mounted so ventilation air cannot be recirculated.
