Criteria For Filter Selection/Flow Rates - Hagen Fluval 104 Manual Del Usuario

Lift-Lock Clamps
Two prominent clamps expedite the removal of the motor from the filter unit. By simply lowering
the clamps, the motor unit is separated from the filter.
Hose Lock Nuts
Safety connectors ensure a tight, leak-proof seal for all hose connections.
Criteria for Filter Selection
Flow Rates
Fluval Filters are available in four models to handle all aquarium requirements, from the smallest to large
commercial aquariums. Flow rates start at 480 liters per hour up to 1300 liters of hourly turnover
(Pump Output) depending on the model. Important factors in the choice of any filter are the filtration volume
and flow rate. The combination provides the essence of good filtration.
Water circulation is required to maintain oxygenation of the aquarium to sustain bacteria and biological
filtration. The more water filtered per hour, the cleaner the aquarium will remain.
Fluval's combination of contact time and flow provide the ideal filter function.

Filter Area
The Fluval 4 series maximizes canister volume in all four models to provide more places for specific media
as well as increase the actual contact path through the canister. The filter chamber has been redesigned to
provide greater volume in its modern, aesthetic design. The more filter media volume, the greater the
mechanical efficiency and biological activity for the filtering process. Fluval meets this criteria.
Fluval Operating Characteristics
The intake stem can be placed anywhere in the aquarium; ideally in a location that can be easily disguised
by decoration. The most usual placement is on the back wall of the aquarium. The intake stem draws water
and suspended debris near the aquarium's bottom into the filter unit by siphoning.
Water flows through the input assembly and into the unit. It passes through the Foam Screen Frame which
strips most particulate matter from the passing flow and holds it. It then must flow down under the first media
basket and start its journey up through the grid into the rest of the media. The pump draws the water
upward through the media baskets where it must come into contact with each stage of filtration. Tremendous
versatility of media choice is allowed by this arrangement of media baskets. The traditional ease of access to
all media baskets without disturbing the rest of the media is maintained and enhanced by this new
configuration. Filter media removes particles and liquid impurities and can also be used to actively change
the chemical characteristics of the water, depending on the aquarist's needs. As the water flows, it brings
oxygen into the filter, feeding the needs of the beneficial bacteria breaking down nitrogenous wastes.
After passing through each discrete chamber, purified water enters the impeller well to be pumped back
to the aquarium.
