Fluval 4th Generation: Advanced
Filter Design
Fluval Power Filters are designed to provide optimum aquarium filtration using a versatile combination of
mechanical, biological and chemical capabilities. This results in healthier fish and thriving aquatic plants.
Fluval filters are equipped with basic filter media. Additional filter chambers are available for many different
filter materials of your own choice. (See section on "Fluval Media Selection" for a complete listing of Fluval
Filter Media).
Motor Unit
Fluval's motor is hermetically sealed with epoxy to ensure that it will continue to operate without difficulty in
adverse conditions. It does not require liquid or air coolant and can be placed in a closed cabinet with
restricted air flow without affecting the life or performance of the filter. Fluval filters are the leaders in energy
efficiency, moving more water per watt of consumption than other comparable filters. Fluval canister filters
require no motor maintenance. The motor has no moving parts except for the impeller.
Impeller and Ceramic Impeller Shaft Insert
Fluval increases efficiency and long-term durability by providing a removable Ceramic Impeller
Shaft Insert. It provides quiet operation and increases motor life and efficiency.
Self-Cleaning Impeller Well
The Magnetic Impeller Shaft Insert incorporates a self-flushing channel to keep the unit clean and debris-free
during operation. It backwashes fine silt and debris from the impeller well, reducing maintenance to a simple
flush during filter media changes.
Mechanical Filtration Area - Foam Screen Frame
The foam is contained in a convenient, accessible frame. The screen captures large particulate
waste to prevent it from clogging the Biological Filtration Area. The foam's placement ensures
efficient mechanical removal of waste. The massive foam surface captures and lodges large
waste. As water flows through the unit, the waste is broken down into smaller particles.
Biological/Chemical Filtration Area - Stackable
Filter Media Baskets
The media baskets permit full access to all media. This allows for partial or full filter media
changes, based on the user's requirements. Filter media expires at various times. In the case of
biological media, it is recommended to make only partial media changes, so as not to disturb the
biological balance of the aquarium. Fluval's Filter Media Baskets provide a convenient way to
access the various media types to perform full or partial media changes.
Output Nozzle
The Fluval 4
aquarium, rotating horizontal flow direction and the ability to be installed above, at level, or
below the water surface, depending on the aquarist's choice. An important characteristic of any
filter is the way it promotes oxygen replacement in the aquarium. The Fluval Output Nozzle provides excellent
surface agitation for this purpose.
Priming System
A simple pumping motion of the Self-Primer initiates water flow through the check ball that is
incorporated in the intake strainer.
Aqua-Stop
The Aqua-Stop makes maintenance easy by stopping the water flow, permitting you to separate the hose
assembly from the filter in one convenient step. It can be safely used to regulate water flow, without harming
the motor or its components.
