ATS has raised the bar in the field of industrial ventilation as a result of wide and varied expectations of its clients. A range of local exhaust ventilation systems that ensure fumes and mists such as welding fumes, oil mist and other hazardous, volatile or corrosive gases are properly exhausted from factories and large spaces.

Ducted air replacement systems are also crucial to ensure the efficiency of exhaust hoods. Furthermore a correctly designed supply system working in conjunction with LEV Systems can reduce the propensity for condensation and conserve fuel.

The use of a ducted input system is important for two further basic purposes: to create a comfortable environment and to replace air exhausted from the building. It is important to note that while properly designed exhaust systems will remove contaminants they should not be relied upon to draw outside air into the building. If the amount of supply air to the building is lower than the amount of air exhausted, this will result in a negative pressure. The result of negative pressure is air entering the building in an uncontrolled manner through doorways, wall etc. In turn, this may lead to many undesirable effects such as high velocity drafts, backdrafting, difficulty in opening doors and a drop in effectiveness of the exhaust systems etc.

In order to minimise these effects, mechanical air supply systems are needed to introduce sufficient outside air to avoid a negative pressure situation. A properly designed and installed air supply system will provide both replacement air and effective environmental control. Air will enter a building in an amount approximate to the exhaust air whether or not provision is made for this replacement. However, the actual exhaust air flow will be less than design if the plant is under negative pressure. If the plant is tightly sealed, a severe decrease of the exhaust flow rate will result.
