This Motor Head for 407 Canister Filter is a dedicated replacement head for the Fluval 407 Performance Canister Filter, ensuring your filtration system continues to run smoothly, quietly and efficiently.
It is ideal when the original head has become worn, noisy, cracked, or difficult to prime, allowing you to refresh the filter without disturbing established biological media in the canister.

What is included

• Complete motor head assembly for Fluval 407 (A449).

• Factory‑style seals and housing designed to lock onto the 407 canister body.

Please note:
The replacement motor head does not include the magnetic impeller or impeller cover, which must be transferred from the existing unit or purchased separately if damaged.

Compatibility

• Designed for: Fluval 407 Performance Canister Filter (model A449).

• Suitable for aquariums filtered by a 407, typically around 50–100 US gallons / 150–500 litres, depending on stocking and setup.

• Can be used on freshwater and marine systems where a 407 is already installed.

Benefits for beginner aquarists

• Easy upgrade instead of full replacement: Replacing only the motor head keeps hoses, media baskets and biological media in place, reducing disruption to your aquarium’s beneficial bacteria.

• Reduced noise and improved flow: A new head can help restore original circulation performance and reduce rattling or humming caused by worn motor components or warped housings.

• Clear, straightforward handling: The 407 series uses lift‑lock clamps and an AquaStop valve system, making removal and re‑installation of the motor head simple even for first‑time users.

Basic replacement guidance

For safety and best performance, beginner aquarists can follow these general steps when changing the motor head:

1. Turn off and unplug the filter from the mains before any work.

2. Close the AquaStop valve on the hose connector to prevent water flow.

3. Release the lift‑lock clamps and carefully remove the old motor head from the canister.

4. Transfer the existing magnetic impeller and impeller cover into the new motor head, checking they spin freely and are free from debris.

5. Inspect and lightly lubricate the main motor‑head o‑ring if recommended, ensuring it sits correctly in its groove for a proper seal.

6. Re‑attach the new head onto the canister, close the clamps, open the AquaStop valve and prime the filter before plugging it back in.

This straightforward procedure allows even new aquarists to restore their filter with minimal risk to livestock, as the biological media inside the baskets can remain underwater in the canister during the swap.
