VTs 14-46 fans are manufactured of qualitative carbonaceous steel and intended for movement of air and various gas mixes which aggression in relation to carbonaceous stalyam of ordinary quality does not exceed similar characteristics for air with the temperature of +80 °C. Besides, gas or air should not contain sticky substances, fibrous materials, and also dust and various solid impurity in number of more than 150 mg/m3.
Fans centrifugal 14-46B (explosion-proof of diverse metals) are intended for movement of the air-gas or steam-air explosive mixes IIA, IIB of the categories which are not causing corrosion of carbonaceous steel and aluminum with a speed over 0,1 mm a year. Content of dust and other solid impurity at the same time should not exceed 0,1 g/m3. It is important to note obligatory lack of explosive and sticky substances, and also fibrous materials near centrifugal installations. Temperature should not exceed 80 °C. Centrifugal fans cannot be used for movement of air-gas and pylevozdushny mixes from technological installations in which explosive substances heat up higher than temperature of their spontaneous ignition or are under excessive pressure.
The Fans Centrifugal (FC) 14-46 are used in stationary systems of heating and air conditioning and ventilation of production, public and residential buildings, and also in other sanitary purposes. They can be divided into two groups on the direction of the movement of the driving wheel conditionally: the right rotation - in this case if to take a detached view absorptions, the wheel rotates clockwise - and left - when the wheel rotates counterclockwise.
