Fans ВНЖ is a heavy-duty corrosion-resistant equipment of high and medium pressure. Its spiral body is a snail – it has a removable quarter and 32 curved forward blades. The flowing part of the fan in contact with an aggressive medium is made of high-strength alloys such as 10Х17Н13М2Т, 06ХН28МДТ, etc. A stainless fan is manufactured in the right and left direction of rotation.

Fan ВНЖ 15.5 and 13.5 have found their application in the production of mineral fertilizers. They are included in the complete set of production technological lines and move aggressive non-explosive gases with a temperature below 200 ° C. The solids content in the transported medium should not exceed 1 g / m³.

Centrifugal machines ВНЖ work on the principle of unilateral suction. His snail can change the angle of rotation within 0 … 270 degrees, every 15 degrees.

The operation of stainless fans is possible in a temperate climate with the first category of accommodation. The outside temperature can fluctuate between -40 … +40 ° C. The installation location of the fan must be protected from high vibration rates.
