When discharge smoke, grease, odours at a low level, a combination of kitchen exhaust treatment technologies is often employed to achieve the most cost effective outcome. The factors that must be considered include having to be close to the boundaries, windows and air intakes or natural ventilation devices.
A tenancy lease agreement would indicate kitchen exhaust filtration system to be installed in the premises as a condition of the lease. Usually duct connection is installed in the tenancy and the owner must maintain and have full responsibility of the kitchen exhaust filtration system.
An individual tenancy filtration system maybe installed because issues may arise with residential tenancies which live above the retail precinct. The local the council who protect the local residence are becoming less tolerant of offensive smoke and odour from ventilation systems.
