To arrange ventilation, complex architectural solutions are increasingly being used, which involve the creation of an extensive network of air ducts. To install such lines, various devices are required for fastening and connecting air duct pipes, including an air duct insert, without which no complex project can be completed today.

Draw your attention to! We sell round ventilation inserts of the highest quality on truly favorable terms, providing all the necessary guarantees!
The round insert is intended for connection to an air duct system of a different diameter. To install the insert into the air duct, you need to make a hole in it. The round ventilation insert is mechanically attached to the air duct using pop rivets or self-tapping screws. Before installation, a layer of silicone sealant must be applied between the insert and the duct.
Round duct insertion
Plastic ventilation inserts can be made to order in different diameters. The price for an air duct insert depends on the diameter, height and material.

Rectangular
Photo 1. Options for direct insertion into the air duct.
To connect ventilation and air conditioning systems, a rectangular insert is used, which is mounted into the wall of the main air line. To do this, a quadrangular hole of appropriate size is made in the wall. The side of the main rectangular line must be 50 mm or more larger than the hole. A rectangular insert is usually fastened mechanically using hardware (self-tapping screws or pop rivets). To ensure complete tightness and strength, a thin layer of sealant, most often silicone-based, is applied before installation.
In the standard version of the recessed element, the large hole has a smooth flanged end, and connecting strips are installed around the perimeter of the smaller hole.
The width and height of this shaped product can range from 100x150 mm to 1200x1200 mm.

What is a sidebar: purpose and features
A tie-in is a type of shaped products that are intended for the installation of ventilation lines, connecting structural elements in any plane, diverting or supplying an additional branch from the central shaft, and transitioning from one type of ventilation ducts to another. The product is often used to upgrade existing ventilation, when wiring to create a more airtight joint, in order to save money when replacing a tee.
The purpose and design of inserts are of three types:
- Round, designed for installation on rectangular channels as the beginning of a branch or replacement of a tee. Also for changing to a round pipe.
- The rectangular one is mounted on round and rectangular shafts.
- The saddle insert is designed for installation on round elements. It is equipped with a bend on the docking side.
All types of shaped fittings have a flange on one side for a sealed connection with the surface of the pipeline, and on the other, a straight edge for a flange connection.
Purpose and design
The main purpose of the ventilation system is to provide the room with the necessary amount of clean air to maintain a comfortable state of a person and maintain an optimal microclimate of the space. Supply and exhaust ventilation will cope with this most successfully, because this system, according to its operating principle, resembles the human body, which inhales and exhales. It will provide people with enough oxygen, which eliminates the possibility of oxygen starvation and helps improve health, and noise suppressors can easily suppress excess noise.
The insert into the air duct is the most important shaped part with which the system is installed into the wall of the air duct.
The device remains sealed and participates in the filtration of passing air, so for its manufacture it is best to use high-quality, reliable and durable materials, for example, stainless or galvanized steel. Professionals use several technologies for inserting junctions; let’s consider three main ones:
Straight for rectangular duct
This type is used when it is necessary to install a rectangular insert into a round air duct. The structure is installed in the wall of the main air line. As standard, the product has a smooth end with a flange. The hole should be 50 mm smaller than the main rectangular pipe. The small hole is equipped with connecting strips. The dimensions of the direct insert for a rectangular air duct range from 100 to 1200 mm.
After completion of installation work, it is necessary to ensure complete tightness of the system. For this purpose, special silicone insulation is used.
Straight for round duct
The part is used to connect a round to a rectangular air duct. This insert has a round cross-section and is mounted similarly to a straight one. The main difference between this device is the holes in the form of circles. The pipe diameters range from 100 mm to 1250 mm.
Corner for round duct
It is used to connect a round air duct at an angle with the customer selecting the insertion height, which should exceed 5 cm. The design of the part is the same as a straight line for a round air duct, but there is an important difference - the air duct is made at an angle. It is convenient to attach such a device, thanks to the different sizes of the insert. This type has a big drawback - low productivity.
To avoid this disadvantage, an innovative technology for manufacturing more advanced spiral-wound air ducts was invented; they are the most durable and significantly increase productivity. With the increasing demand for ventilation, for the convenience of consumers, components have been created that can cope with any task. For example, if it is necessary to change the diameter and shift the axis, adapters with a circular cross-section are used.
Specifications
The performance characteristics of air ducts must comply with standards and regulations to ensure system reliability, increase service life, and ease of selection of components. Manufacturers can deviate from the norms only in the case of an individual order.
First of all, the boundary of the nominal sizes is clearly marked. In the case of diametrical products, this figure indicates the internal size of the air duct and can be equal to 10, 12.5, 14, 16, 18, 20, 22.5, 25, 28, 31.5, 35.5, 40, 45, 50, 56, 63, 71, 80 , 90, 1 00, 112 and 125 cm.
Rectangular components have a useful (installation) length equal to values from 10 to 250 cm in increments of 5. When designing a highway, it is necessary to take into account the recommendations for an aspect ratio of 1:4, in extreme cases 1:6.
The next important characteristic is the rigidity of the main and shaped elements, which is ensured thanks to the spiral-wound manufacturing technology. If the standard requirements are not met, there is a high risk of destruction of the line during assembly.
Installation Features
Regardless of the installation location of the air ducts - outside or inside the room, the installation technology is always the same. The ventilation structure is mounted in two ways: in a plane or in a pipe. A direct insert is installed in a plane to secure a round air duct into a rectangular pipeline. In order to make it possible to secure it, a special hole is made in the structure. To ensure the rigidity of the part, it is important to ensure that the transverse dimension of the wall exceeds the size of the hole by at least 5 cm.
Pipe installation is used to install a round air duct into a wall of the same shape as the pipeline using a connecting pipe. In order for the device to be securely fastened, it is necessary to make a hole of a certain diameter and apply a layer of silicone insulation to it. The corner one is mounted in the same way as the previous options. The finished mechanism can be secured using spot welding or special rivets. The installation is attached to the wall surface or to the ceiling. In order to make an additional outlet in the desired direction, special structural units are used - tees.
Provided that the inserts are installed correctly and a reliable seal is created, the elements of the ventilation system will last a very long time and will easily perform the following functions:
- Getting rid of excess heat, moisture and harmful substances.
- Eliminate combustion products and prevent smoke from entering the room.
- Maintaining a comfortable atmosphere and air humidification.
- Removing excess dust and harmful fumes.
- Ensuring optimal temperature for the room. Refrigeration supply for storing food or carrying out necessary technological work or heating to maintain a comfortable state of people.
