Air-powered

Defined as the volume of air needed to be drawn out or provide a room for a certain period of time. Several methods can be used to calculate the air flow requirements:

FAN CHOICE

The fan selected must be included in the parameters described as:

• Ground -. Industrial, commercial, family
• The nature of air and its characteristics - clean air, air and dust or grease, especially liquid (gas)
• The nature of the installation process - air supply and exhaust fans, wall fans, roof fans, Couplings winds, Wind guidelines, the exceptional conditions
• Requirements of the air flow and pressure drop
• Acceptable sound levels inside and outside the room
• Type of power supply. - Single-phase, three-phase, voltage, frequency, and other parameters can be considered for selection as: size, motor speed control, mounting accessories etc.

Rules

These rules allow you to change the aerodynamic parameters:

LOSS OF PRESSURE

To get the air flow in a pipe system, it is necessary to overcome the resistance of the system:

  - Due to friction in the pipe length

  - Due to the features of the system (curved cross-section changes, filter, mouth wind, etc..)

These losses must be accurately calculated to choose the right fan and airflow satisfactory.
