We provide the best Ventilation Solutions Services in Pune. In the case of decentralized mechanical ventilation, a distinction is drawn between systems with and without heat recovery: Ventilation Solutions  systems with heat recovery have an individual appliance installed in the external wall in every form  to be ventilated. For this, there are systems with two fans and heat recovery via a countercurrent heat exchanger for example. When choosing suitable decentralised appliances, it is also important to look for the lowest possible sound emissions and at ease of cleaning and maintenance.
