A well-thought-out industrial ventilation system is capable of efficiently and without interruptions over a long period of time to carry out optimal air exchange and help maintain a comfortable atmosphere in the premises in order to live and work. Correctly selected fan models play one of the most important roles in this.
For example, if an industrial ventilation system has a high aerodynamic resistance and a significant length of air-conducting channels, the best solution would be buy a centrifugal fan . Among their advantages are economy, compactness and good performance. That is why they are often used in large buildings with a large number of rooms, in which large numbers of visitors and staff can stay at the same time. This can be the case in religious buildings, administrative, sports and the like. The price of centrifugal fans may fluctuate depending on the parameters and materials, as well as some design features. For example, the direction of bending of the blades affects the lateral dimension of the impeller and the speed at which it rotates. This, in turn, affects the size and noise generated by centrifugal fans during operation.
Sometimes the user expects that his industrial ventilation system will guarantee proper air exchange without creating annoying background noise. The way out in this case is to buy noise-insulated fans. Their housings are manufactured in such a way as to absorb sound vibrations. At the same time, these devices "can boast" of decent efficiency and economy. Cases of noise-insulated fans are plastic or made of galvanized aluminum, and their noiselessness is guaranteed by a double casing design, which has an inner layer of vibration-damping dense material. The price for noise-insulated fans will naturally be slightly higher than for a model with a conventional case design. Nevertheless, their purchase is justified by the fact that visitors or customers of a cafe, entertainment center and other facilities, the industrial ventilation system of which is equipped with such equipment, will not complain about excessive noise.
In most situations, in order for the industrial ventilation system to provide an effective supply of fresh air and /or exhaust exhaust, the owners of the premises decide to buy a duct fan. Different configurations of their bodies (round, rectangular, square) allow you to choose exactly the one that is suitable for installation on air ducts with the same cross-sectional shape. In addition, you still need to correctly calculate the volume
