The Mirovent company offers equipment that provides soundproofing of ventilation systems. Among the widely used models are silencers for rectangular ducts. These devices are distinguished by the fact that between their body and the internal channel, which are made of galvanized style, there is a layer of insulation of 100 mm. Mineral wool or ultra-thin glass fiber is used here as a sound-absorbing substance.

These devices significantly reduce the level of aerodynamic sounds generated by fans and air conditioners. Such silencers are installed on the air ducts of the flow and exhaust ventilation systems.

Operating conditions

It should be noted that the flow in rectangular ducts is distributed rather unevenly. Due to the appearance of turbulent zones inside the pipe, additional noise arises. This places special demands on the efficiency of equipment designed to reduce it.

Sound attenuators for rectangular ducts are designed for transferring air and chemically passive media. The devices must meet the following conditions:

• maximum temperature - +800 °С;
• relative humidity - up to 60%;
• climatic compliance - category U;
• accommodation category - 3.

In order to reduce the noise produced by the fans as much as possible, when installing sound attenuators for rectangular ducts, it is recommended to provide a straight section about a meter long in front of them.

Mirovent offers equipment at the best prices. We work directly with the manufacturers of these products, so the quality of each product is guaranteed!

Consider ventilation silencers in more detail.

Rectangular

Rectangular silencer for ventilation is a box made of sheet metal divided along the air flow by plates covered with soundproofing material. Used for soundproofing fiberglass or mineral wool.

Basically, rectangular ventilation silencers are used for installation in air ducts through which a large volume of air passes. The gap between the cells varies from 75 to 300 mm, while with a decrease in the cells, noise decreases, but pressure losses increase. To reduce pressure losses resulting from friction, the sound-absorbing material is coated with an anti-abrasion compound or a thin layer of plastic. A variation of the rectangular ventilation silencer is the roof ventilation silencer. When choosing a rectangular sound attenuator for ventilation, it is necessary to take into account its "clear area" through which air passes, and not the landing (connected) size of the air duct.

Round

The round silencer for ventilation consists of round pipes, one of which is inserted into the other. Outer pipe round sound attenuator for ventilation must be smooth, and the inner perforated. The gap between these pipes is filled with soundproofing material. The dimensions of the inner pipe correspond to the dimensions of the air duct into which the round silencer for ventilation is mounted.

Round silencers are used for ventilation for installation in a system with air ducts up to 500 mm in diameter. For a city apartment, it is necessary to install a full-fledged supply and exhaust ventilation, with a silencer. Round silencers for ventilation can be elements of both supply and exhaust systems. Most often, round silencers for ventilation are installed between the fan and the main air duct. If transit air ducts cross a room with a high noise level, then a round silencer for ventilation is mounted on the site ventilation system behind this room. To prevent the spread of noise through the air ducts from room to room and when increased requirements to the sound insulation of individual rooms, it is advisable to install them directly in front of the air distributor or immediately behind the grille of the exhaust ventilation system. When installing air intakes in supply system near window openings, it is necessary to install a round ventilation silencer immediately behind the air inlet damper to reduce the noise coming out of the air intake grille.

Flexible

Flexible silencer for ventilation are mounted instead of round silencers, if the installation space is limited. Flexible silencers for ventilation are made of two-layer aluminum foil with reinforced cord. Between layers of foil layer of soundproofing material.

The length of the flexible silencer for ventilation is 1 meter. Great replacement for a round hard muffler!

Silencers

Silencers for ventilation systems

In ventilation systems, various ventilation equipment is installed, during the passage of which the air flow forms aerodynamic noise and vibrations, which spreads far beyond the air ducts.

Reducing the noise level during ventilation is achieved by installing such devices as silencers, and their use allows not only to ensure compliance with sanitary standards in production, but also to increase the period of trouble-free operation of ventilation equipment.

Several types of sound attenuators for rectangular and round air ducts are manufactured at the factory of Ventilation Factory GalVent, while you can order both standard size silencers from the product catalog, and silencers of any diameter/section with the required length. Silencers of non-standard sizes will be calculated by the company's designer, after which the sales manager will agree on the final cost of the silencers.

Silencers for fans in ventilation ducts

Fans are the main source of noise in ventilation systems, and most often silencers are installed immediately after the fan before entering the main air duct. Also, silencers can be installed after the wall of a room with a high level of noise in case the ventilation ducts cross it.

It should be noted that when installing an exhaust ventilation system, to reduce noise not only in the premises, but also outside, two silencers can be installed before and after the fan.

The number of silencers in the ventilation system directly depends on its design and the complexity of the layout of the ventilation ducts. Dozens of sound attenuators can be installed in one ventilation system, since to achieve the maximum effect, it will be necessary to install a sound attenuator after each ventilation element that creates noise and vibrations.

Types of silencers for air ducts

Silencers are divided into roof and channel, while duct silencers They are classified according to their cross-section into round and rectangular.

Round silencers include the tubular GTK and Eurostandard series, which are used in systems with round spirally wound and straight-seam air ducts. Efficiency tubular silencers confirmed when working in systems with a cross section of up to 500 mm, installed mainly in rooms for domestic needs.

To rectangular silencers include lamellar silencers of the GP and Eurostandard series, as well as GTP silencers. Lamellar silencers are most often used in industrial premises or for industrial needs, where the installation of ventilation ducts with a large cross section is required. In lamellar silencers, the sound-absorbing material is evenly distributed over the section of the silencer, which makes it possible to more effectively reduce the noise level.

Price list for silencers

To buy a silencer for a ventilation system, it is enough to send an application for the selection of a silencer, and the company's specialists will calculate the parameters of the silencer. As a result, you will receive the parameters of the desired silencer, which will most effectively reduce the noise level.
