ActronAir Indoor Evaporator Fan Deck 9x7 S 750W is the higher-wattage variant of the 9x7 deck range, suited to indoor units where greater static pressure capability is needed to overcome longer or more restrictive duct runs while maintaining airflow at each zone register. At 750W with a 20uF run capacitor, this deck draws more current than the 600W variant -- correct circuit breaker sizing must be confirmed before replacement. Isolate power at mains before replacement -- live work on fan assemblies is dangerous and must only be performed by a qualified technician.
