Fan centrifugal BEHTC VTsUN 200х93-0,55-4Description
Centrifugal fans of unilateral absorption in the spiral rotary case with the krylchatka established on an axis of the serial three-phase asynchronous engine. Productivity - to 19 000 m3/h. Are intended for forced-air and exhaust systems of ventilation.
Forced-air and exhaust systems of ventilation of rooms of different function. Fans can be used as the completing elements to ventilating installations and installations of air conditioning. External installation is allowed.
The case of the fan is manufactured of steel with a polymeric covering. The VTsUN fan can be executed as with the direction of rotation of the driving wheel to the right, and to the left. In each of options there are several provisions of the case that does possible accession to an air duct at any angle with a step in 45 °.
At production of fans polar three-phase asynchronous engines on which axis the driving wheel with forward the bent shovels manufactured of galvanized steel is installed are used 2kh-, 4kh-, 6ti-or the 8th. Application in engines of rolling bearings provides the big term of operation. For achievement of exact characteristics, low noise level and safe operation of the fan each turbine at assembly passes dynamic balancing. The engine in the fan has a class of protection of IP 54.
Adjustment of speed
Adjustment of speed of the fan can be carried out by means of the autotransformer or frequency regulator. Several fans provided that the general power and working current will not exceed nominal parameters of the regulator can be connected to one control device at once.
Can be established as in air-ventilation chambers and installations for conditioning, and separately. In the latter case - it can be connected to air ducts as two branch pipes (exhaust and soaking up), and one exhaust. The exhaust and soaking-up branch pipes have rectangular and round section respectively. Giving of food is carried out via external plugs.
