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 replacement air is only allowed to enter the building via louvered apertures then there is no control of the replacement air.
This can result in reduced efficiency of the extract hood, undiluted hazardous air remaining in the vicinity of the operators and condensation issues for the products and building.
Air Technology Systems design, install and commission all of the various aspects of the systems that are needed to provide a comprehensive solution to any industrial heating, ventilation or air conditioning problem. This includes the ductwork manufactured in a variety of materials, odour, mist or gas filtration plants to scrub the air and all air replacement equipment give a high ventilation efficiency.
