Hagen Fluval Intake Strainer for Filter 104–404 (Replacement Part, Model 011331)

The Hagen Fluval Intake Strainer for Filter 104–404 is a replacement intake component designed to fit Fluval canister filter series 104 through 404. It prevents large debris, gravel and small aquatic organisms from being drawn into the intake tube, helping to maintain consistent water flow and protect the motor and impeller. This replacement part is intended for routine maintenance and part renewal to ensure continued filtration performance and reliable operation of compatible Fluval filters.

Advantages

The intake strainer restores effective intake protection by blocking larger particles while allowing normal water circulation. Its durable construction resists typical aquarium wear and minimizes the risk of clogging or damage to internal pump components. As a direct-fit replacement for compatible Fluval filter models, it simplifies maintenance and reduces downtime compared with more extensive repairs.

Suitable for

• Home aquariums using Fluval canister filters in the 104–404 range
• Routine filter maintenance and part replacement
• Protecting pump and impeller from debris and small inhabitants
• Ensuring consistent intake flow in freshwater and saltwater setups

Key specifications

• Compatibility: Fluval canister filter models 104–404
• Function: intake protection and debris screening
• Material: durable plastic suitable for aquarium use

How to use

Turn off and unplug the filter before performing any work. Remove the existing intake strainer by detaching it from the intake tube according to the filter manufacturer's service instructions. Inspect the intake tube for accumulated debris and clean as necessary. Install the replacement Hagen Fluval intake strainer by sliding or snapping it onto the intake tube until it seats securely. Reassemble any removed components, prime the filter if required, and restart the unit. Verify steady water flow and check for leaks after installation.

Usage recommendations

Regularly inspect the intake strainer during scheduled maintenance and rinse under aquarium water to remove trapped debris. Replace the strainer if it shows cracks, excessive wear, or if flow problems persist after cleaning. Avoid using harsh chemicals for cleaning and ensure all parts are secured to prevent suction hazards to small aquatic life.
