HOW TO SELECT THE RIGHT FANS

EFFICIENT VENTILATION

Ventilation is not always applied properly and this can mean that while two rooms may have the same rate of air flow, one may be better ventilated than the other and thus have better quality air.

The efficiency of ventilation is defined by the capacity of a ventilation system to remove pollutants from a confined environment. A highly efficient system can therefore provide excellent air quality with a lower rate of airflow than a less efficient system. The efficiency of ventilation depends on certain factors such as:

• The characteristics of the system
 • The characteristics and position of the air outlets
 • The type of room

VENTILATION SYSTEMS CAN BE SPLIT INTO TWO CATEGORIES:

  1. Domestic ventilation systems
  2. Industrial ventilation systems

The key factor however is always the flow rate, i.e. the amount of air to be extracted from or introduced to a room over a given period of time. This rate is usually expressed in L/s.

THE CHOICE OF VENTILATOR SHOULD BE BASED ON:

  •  The type of room: domestic, commercial, and industrial
  •  The volume of the room
  •  The type of airflow to be ducted and its characteristics
    •  Fresh air
    •  Air + duct
    •  Ducting special airflows
  •  Type of possible ventilation system configuration
    •  Wall-mounted system with ducted extraction
    •  Wall-mounted system with direct extraction to exterior
    •  Window mounted extractor
    •  Specific extractors for long ducting
    •  Systems for centralized units
  •  Positioning of air inlets and outlets
  •  Special conditions: temperature, humidity
  •  Required airflow and pressure
  •  Noise level
  •  Type of power supply: single or three-phase
