Fresh air is the basic requirement for a healthy and productive workplace. That means it is also the basic requirement for comfortable staff.
In any workplace, industrial or commercial, factory or office they all need to have constantly circulated fresh airstream to replace and ventilate stale air.
Not only is ventilation with air filtration and purification a fundamental to a healthy work environment, it also ensures that machinery is not damaged or components and products spoiled by fumes or condensation. Ventilation can come in various forms and can include for simple input and extract fans, spot extraction, and heat recovery ventilation such as a Mitsubishi Lossnay system which not only ventilated but reduces energy bills by extracting stale air and recovering the heat or cold, this is then used to either warm or cool the incoming fresh air.
Lead acid motive power batteries produce hydrogen gas and other fumes at 80% recharge point, making proper ventilation in the battery charging area extremely important.
