Fan axial OCA-201
Use of fans axial for systems of forced antismoke ventilation OCA-201
Axial fans a subtime of OCA-201 are used in systems of antismoke retaining ventilation. Fans axial the low pressure of OCA-201 perform function of creation of excessive pressure.
Design features of fans axial for systems of forced antismoke ventilation OCA-201
Fans of the axial OCA-201 series of low pressure consist of the driving wheel of a new design, the all-welded case and the asynchronous engine placed in the case. The driving wheel with the adjustable angle of installation of shovels. Shovels are executed volume, casting under pressure. Live section of a stream of air is most increased that gives considerable reduction of speed at the exit. Thanks to a new design of a wheel axial fans are designed with the highest static efficiency at pressures of 100 Pas – 300 Pas. The short case of the fan the subtime does not close the engine completely and has the reduced weight. Otbortovana flanges also set the increased rigidity and accuracy of geometry. In the absence of network on an entrance it is necessary to use an entrance collector of BKO-OCA or an adapter toroidal PET-OSA. The direction of a stream always from a wheel on the motor irrespective of orientation. All case elements of the axial fan have a galvanized covering.
