Centrifugal radial fans

 

The fans are working hydraulic turbomachines for air or gas, where the mechanical energy is transformed into hydraulic - kinetic and potential. The main energy changing element is the impeller, which, according to the direction of the air or gas flowing going through it, can be radial, diagonal or axial.

CZBA Ltd. offer radial fans for high and medium pressure, for fume extraction and for air transport. The fans find a great application in the common engineering. They are widely used in the ventilation and air-conditioning installations in houses, public and industrial buildings; in central and local ventilation of mines; in pneumotransport; in agriculture, etc.

 

Choice of a fan

When it is choiced a ventilator must consider a kind of working place, the characteristic of the air, the type of ventilation system, the necessary flow and pressure, type of electric supply, the requirements of noise level and so on.

• type of fan
• airflow [m3/h]
• full pressure [Pa]
• motor power [kW]
• rotational frequency [min-1]
• position of the housting
• characteristic of the fluid - including dust, temperature, aggressiveness, explosiveness, adhesiveness of the dust and other specific features
• Fan accessories - frames, flanges, vibroframes, protection grids, vibroisolators, flexible
  joints and other.
