We want fresh air always and in every room of our homes and office.
However, it is possible to breathe fresh air inside as if you were outside and fully enjoy your home and office.
Most essential to providing fresh air to your home/office is properly managing incoming and outgoing air for your climate conditions, seasons, temperature and humidity levels.
Ventilation is thus a necessity.
These fresh air systems exchange stale indoor air and pollutants for fresh, filtered air from outside.

Basement / Car Park Ventilation

In an enclosed space, such as underground car parks in malls, smoke is a real threat to life and it also causes significant issues for fire fighters dealing with fire, in case there is a fire breakout. Hence,these places need a good ventilation system for the removal of exhaust gases and replacing the wasted air with fresh air inside the car parking space so that the people inside do not get suffocated or choked.
