The V432 and V433 gutter fans are low flow and high pressure fans, intendes for the heavy transport of air loaded with cement flour, through the gutter of cement factories. From silos, the ground cement flour falls into the pneumatic gutters from where it is transported with the help of the air flow produced by the fans, in order to burn in the furnace for transformation into cement.
You can choose a centrifugal fan from our product range or contact us to offer you solutions fully adapted to your needs.
Centrifugal fans are fans for transporting air loaded more or less with dust or dust particles. The air or the material to be transported taken through a suction mouth is conveyed tangentially with the fan rotor, passed between the rotor blades making a centrifugal circulation of it and the transported materials and evacuated through a discharge mouth, to which it can be mounted, possibly, a tubing.
In general, the principle of operation of industrial fans starts from the production and movement of fluid currents in liquid or gaseous state, in various working environments. Their movement is due to the rotational movement of the main part of the fan - the rotor, which, in turn, determines the movement of liquid or gaseous fluid, air in most cases.
The movement of the rotor determines the evacuation of the vitiated air, of the noxious substances from the working environment in case of corrosive environments, of the transport of some powdery materials, etc. At the same time, the fan can ensure the introduction of fresh air for cooling some equipment, especially for those who work in environments with high temperatures, but also for refreshing the air in closed spaces. Centrifugal fans ensure the change of the direction of the discharged flow in relation to the aspirated flow in order to meet specific operation and installation requirements.
Ventilatoarele industriale produse de Ventilatorul 1932 raspund tuturor cerintelor tehnice de operare in medii toxice si grele.
V20T – Fans with medium flow rates and medium pressures
The fans from V20T family are destined for heavy pneumatic transport, with dust content 50 ÷ 200 g / m3 or wood chips, sawdust, plastic granules. They are driven by wheels with belts R or coupling C. Wheel-operated fans are usually made for cold gases with a temperature lower than 80 ºC, and in special construction they can also be made for hot gases up to 350 ºC on order basis. Flow Q = 500 ÷ 630000 m3 / h, pressure H = 212 ÷ 1000 mmCA.

VCT – Fans with medium flows and medium pressures
The VCT family fans open propellers are intended for heavy transport, with a dust content of 50 ÷ 200 g / m3 or sawdust, plastic granules. The fans are executed in direct actuation D (the fan propeller is directly coupled on the motor shaft) for air movement with the temperature up to 75ºC within the limits allowed by the requests of the shaft head of electric motors, or actuation by coupling C for heavy propellers (generally over diameters greater than Ø 710) and for temperatures higher than 75 ºC. they can also be made of stainless steel for corrosive media, as well for the circulation of explosive media (gas groups 2A, 2B, 2C). Flow Q=1000 ÷ 22400 m3 / h, pressure H = 240 ÷ 300 mmCA.

Centrifugal industrial fans
The fans from the V32T family for air movement with low dust content, less than 50mg / m3, smoke and neutral gases. The fans are executed in direct actuation D (the fan propeller is directly coupled on the motor shaft) for air movement with the temperature up to 75ºC within the limits allowed by the demands of the shaft head of electric motors, or actuation by couplings C for heavy propellers (generally for diameters greater than Ø 710) and for temperatures higher than 75 ºC. They can also be made for corrosive stainless steel media, as well as for the circulation of explosive media (gas groups 2A, 2B, 2C).
On request, fans that work/convey excessively harsh and/or corrosive environments can be made with special protection. The protection of excessive corrosive agents, chemical and/or mechanical, is done by applying on the entire surface of the propeller and the casing an outer protective layer, based on ceramic polymers (Pro Guard CN1-M) Flow Q=2240÷250 000 m3/h, pressure H=220÷340 mmCA.
