Ventilation is a key requirement for most businesses. It is important that your business or place of work has a good air flow, whether it’s an office, shop, dental practice or gym, ventilation is imperative to the health and safety of both your staff and the general public. Ventilation systems work by extracting stale air from a building while allowing fresh clean air to enter from outside. This improves overall air quality by ensuring there is a flow of fresh air coming into your work place.
