In an industrial context, ventilation is usually employed to remove airborne contaminants arising from processes or machinery. Satisfactory ambient conditions can be achieved by dilution where contaminant sources are weak, of low toxicity, and are either scattered or mobile.

Sources of industrial contaminants often require large extract airflow rates to ensure that the released pollutant is effectively captured and conveyed away by the extract system. In these instances, particular attention should be given to ensuring adequate replacement or make up air.

For certain processes, such as paint spraying, filteration of the incoming air may be necessary. Similarly it may be necessary to remove the contamination from the exhaust air before it is discharged to the outside.

The basic factors that influence the level of mechanical ventilation are:

  • Quantity of air required
  • Quality of air required
  • Consistency of control required
  • Isolation required from the external environment

Because of the factory environment, mechanical ventilation is required, given the likelihood of high airflow rates and the need to treat the incoming air.

The mechanical ventilation system can be designed to provide constant or variable flow rates that are distributed as required throughout the building. When a building is located in a noisy environment, the mechanical ventilation can be used with the appropriate acoustic treatment.

Ideally industrial ventilation systems should limit the exposure to workers to airborne contaminants to zero, or as near zero as is practicable. If extract rates are too low, short term or long-term damage to health will occur or, at the very least, serious discomfort will be experienced.

Industrial ventilation is a method of controlling worker exposure to airborne toxic chemicals or flammable vapours by exhausting contaminated air away from the work area and replacing it with clean air.

Industrial ventilation is typically used to remove welding fumes, solvent vapors, oil mists or dusts from a work location and exhaust these contaminants outdoors. The design and troubleshooting of industrial ventilation systems should be handled by a qualified ventilation engineer or firms specialising in this field.

For general factory ventilation, it is important to consider the use of high level extract fans, either roof or wall mounted. It is also important to consider providing mechanical ventilation systems with back draught shutters or dampers to prevent air infiltration when the fans are not in use.

No matter what your industry or occupation, if you use industrial ventilation, there are certain guidelines you must follow not only for legality purposes, but also for the health and safety of employees and staff.

Industrial ventilation is important because it controls exposure to various types of airborne chemicals and vapours that can be toxic, flammable, and dangerous. A good industrial ventilation system will remove the toxic air and replace it with cleaner air. Although this is more important in some industries than others, each industrial company has a set of regulations, which must be adhered to for the safety of the employees and the safety and purity of the working environment.

Many industrial facilities have processes, which produce hazardous dusts, mists, vapours or gases. Preventing occupational exposure to these substances often requires an extract system engineered to capture and convey the contaminants or products and clean the exhaust stream to recover valuable material or prevent air pollution.
