Silent Filter For Aquarium

Low noise filter – the same advantage of these devices, as well as high performance. Few will want to install a filter that perfectly cleans the water, but rumbles or buzzes like a powerful transformer.

Sources of noise when the filter is running:

– beats, generating vibrations, moving parts of the filter equipment – the axis on which the impeller is mounted, low-quality bearings in the pump electric motor;

– air bubbles that hit the impeller produce noise;

– the difficulty of the pump, which occurs when a large pollution filtering filter substrates;

Silent Filter For Aquarium

– noise generated by air that is sucked into the filter (internal filters that provide simultaneous aeration).

To get rid of the noise that causes air to enter the filter (often this happens when using external filters), it is quite simple – you need to shake it from side to side so that the air that accumulates under the filter head comes out. To reduce the level of noise produced by the intake air, many manufacturers supply their filters with special silencers that are worn on the suction nozzle. If you are not satisfied with the level of reduced noise, it can be reduced even more. Russian aquarists have found such an outlet – instead of the muffler offered by the manufacturer, a silicone tube with a conventional ceramic sprayer is connected to the suction nozzle, and a rotary cock is inserted between the nozzle and the sprayer to regulate the air flow. As the measurements showed, after such an operation this type of noise is reduced to 6 dB, that is, to the level of noise that the breathing person breathes.

The noise produced by blows of air bubbles on the impeller blades, as a rule, disappears as the filter accelerates. If this does not happen – note that the air from the aerator’s sprayer does not get into your filter and move it away from the suction inlets of the filter.

As the filtering substrates become contaminated, the load on the electric motor increases, and when the calculated value is exceeded, it starts to buzz – the output is simple, it is just time to clean the filter.

In the struggle for the buyer, campaigns that produce Fish Tank Filters and are seeking to create the quietest filter for the aquarium, pay more and more attention not only to the high performance of the filter itself, the quality and complexity of filtration, but also the comfort of their operation, which includes no noise when working.

To overcome the noise of its filters, which aquarists complained about in the recent past, the Polish AQUAEL campaign focused on reducing the possibility of transmitting vibrations from the mechanical part of the filter to the glass of an aquarium that acts as a resonator. New models manufactured under the FAN Part Number are equipped with special vibration-damping suckers or optional magnetic holders. The reduction of noise was also caused by the installation of systems enabling smooth adjustment of pump performance, which makes it possible to use it to the extent necessary to ensure the flow of the required force.

Depending on the brand, the filters of the AQUAEL UNIFILTER range are designed for use in aquariums, depending on the brand of the product, from 30 liters to 350. These filters produce significantly less noise than models of the FAN line. This was achieved by changing the location of the axis of the impeller – not vertically, but in a horizontal position. The use of ceramics for the manufacture of the axis itself and the high accuracy of the production standards of the block in which it is strengthened almost completely eliminated the possibility of an axis beating – the noise level dropped sharply with a simultaneous increase in power.

AQUAEL also offers modified Circulator under the brand name of the Turbo model line, which have a capacity of 500, 1000, 1500, 2000 liters per hour. To reduce the noise level, the designers used a ceramic rotor, at the same time it made it possible to use these filters in saltwater aquariums.

In the internal Tetra filters of the IN model line, intended for filtering water in aquariums from 10 to 200 liters, the manufacturer used the thickened ceramic axis of the impeller and thickened heel pads at the base of vibration-damping rubber to reduce the noise of the products.

Even less noisy internal filters Tetra line EasyCrystal Tetratec designed for mechanical and biological filtration in aquariums from 15 to 150 liters. The numbers in the brand name indicate the performance of the filters. It was possible to increase the power of the filters while reducing noise due to the use of a unique magnetic turbine.

The Hagen Fluval three-stage cleaning filters of the U series, which are quite quiet in operation, have been achieved thanks to the new rotor design and the entire rotor compartment. In the external filters of the G3 line, innovative impeller installation design solutions are used, the filters are equipped with automatic air removal systems – all of which have drastically reduced noise compared to previous models.

JBL CristalProfi greenline filters turned out to be very quiet. The designers have achieved noise reduction using special bearings and high-powered electric motors – since the engine does not work at full power – it does not produce noise.

You can buy a silent filter for an aquarium by selecting the filter model of the Italian campaign Sicce that suits your needs. The manufacturer has achieved. low noise of its filters due to the use of a special design development – a floating rotor system, which simultaneously increased the durability of the filters. The external filters of this company are equipped with the SPACEEKO + model line with a self-lubricating and self-cleaning pump impeller system, which significantly reduces noise and prolongs the uninterrupted operation of filters.

The unusually quiet operation during testing showed filters by the Japanese company ADA, which are made by hand and in which not only modern noise-producing technologies are used, but also vibration-damping and noise-insulating aluminum casing. The only drawback of these filters is the need to use a voltage converter from 220 volts to 110 volts.

Among all tested external filters, Eheim filters were the quietest, and especially Eheime Xperience, in which even greater noise reduction was achieved thanks to the use of unique reversible rotors.
