Fluval FX5/FX6 Motor Unit

Industrial-Strength Reliability The Fluval FX5 / FX6 Motor Unit is engineered to handle the most demanding aquatic environments, from massive freshwater predator tanks to complex saltwater reef systems. This unit houses the internal microprocessor that controls the filter’s famous self-priming and air-management cycles. If your filter is experiencing electronic lag, failing to restart after a power outage, or showing signs of motor fatigue, this genuine replacement part restores the system to factory standards.

Key Functional Elements:

• Smart Pump™ Technology: This unit features an onboard circuit board that monitors the impeller 24/7. It adjusts speed to ensure maximum output and automatically stops the pump every 12 hours to allow any trapped air to escape.

• High-Torque Performance: Specifically designed to move up to 3,500 liters of water per hour (pump output), providing the necessary turnover for tanks up to 1,500 liters.

• Thermal Protection: The motor is equipped with an automatic safety shut-off to prevent damage if the internal temperature rises due to a blockage or dry-run.

• Vibration Dampening Design: Built with heavy-duty materials to minimize resonance, ensuring that even this high-powered motor remains surprisingly quiet during operation.

• Direct Integration: Designed to bolt directly onto the existing FX5/FX6 canister base, utilizing the same secure mounting points for a leak-proof seal.
