Centrifugal Fan

OBF Medium Pressure Snail Fan, in other words, OBF series are single suction high efficiency volute fans. The maximum temperature of the fluid being sucked should be 120°C. Some modifications are required in the manufacture of the fan for higher temperature operation. The body is made of S235 steel and all surfaces are coated with epoxy paint resistant to corrosion. Can be made of stainless steel for corrosive and high temperature environments. The fan drive can be selected as a belt-driven, direct-coupled or coupling system. Optionally, it can be manufactured with Ex-Proof feature. It is suitable for use in dusty air suctions, ventilation, drying, mechanical extraction, dust, sawdust or toxic gas systems in all kinds of ventilation systems.

As it is known, Snail Fans, which are used as an indispensable device of ventilation systems, are the most suitable devices to meet the ventilation need in systems with high flow rates and high pressure loss at the same time. It is heavily preferred in heating, cooling systems, dust, sawdust suction lines, ambient ventilation and industrial applications. Snail Fans, produced with Fantürk quality, are selected among various models, the most suitable for the desired operating point in the systems.

Moreover, these fans provide a very efficient operation due to the snail form in their case structure. This form has a positive effect on efficiency, energy saving and desired flow values in the operating device. This is the reason why especially volute fans are chosen in heavy industry and industrial applications. As Fantürk, in addition to choosing the most suitable snail fan to work at the working points requested by our customers from our standard models, special designs can be made and produced for special applications.

The produced volute fans are produced in accordance with the maximum continuous operation at 120°C. This resistance can be increased to 200°C temperature ranges by taking different precautions in the volute body and motor drive type. In addition, production with Ex-Proof feature is possible upon request. Fanturk Snail Fans are produced with direct coupled drive as standard. However, a belt-pulley or coupling drive system can be applied in line with the customer’s request. The throw direction of the snail fans produced thanks to its ergonomic design can be adjusted as desired. Optional sliding system application can be made for these products upon request. In this system, necessary operations can be performed by placing a skid under the motor stand and removing the motor stand and rotor without interfering with the fan body during maintenance and cleaning.
