The Fluval Replacement Motor Head Maintenance Kit for the Fluval 407 Performance Canister Filter (A449) contains several essential components to keep your filter running smoothly. Here's what's included in the kit:

Magnetic Impeller: The impeller is a crucial part of the filter that generates water flow by using magnets to spin and draw water through the filter media.

Ceramic Shaft & Rubber Support: The ceramic shaft provides support to the impeller, allowing it to rotate smoothly and efficiently. The rubber support helps reduce vibrations and noise during operation.

Impeller Cover: The impeller cover encloses and protects the impeller while ensuring proper water flow through the filter system.

Gasket: The gasket forms a watertight seal between the motor head and the canister body, preventing leaks and ensuring the filtration system's effectiveness.

Regular maintenance and replacement of these components are essential to keep your Fluval 407 canister filter functioning optimally and maintaining a healthy aquarium environment. Over time, impellers can wear out, and the ceramic shaft can become clogged or damaged, leading to reduced water flow and efficiency. Therefore, it is recommended to follow the manufacturer's guidelines for maintenance and replace these parts as needed.
