Under traditional kitchen exhaust system design, exhaust ductwork will only remain clean and grease-free only after the electrostatic air cleaner. Ductworks before the air cleaner are highly difficult to clean as it is usually hiding in the celling and working space is too small to clean it completely.
Which means the ductworks before the air cleaner is hidden in the crisis.
In order to better solve this problem, it is usually to either clean the exhaust ducting or shorten the length of exhaust ducting before the electrostatic air cleaner.
The FAF Series is an all-in-one system which is designed to connect to the range hood directly to immediately treat and collect grease-laden fumes with its in-built electrostatic air cleaner, so the rest of ductwork stays grease free. This can not only greatly reduce the troubles caused by the accumulation of grease in the ducting, and also lower the cost of ductworks cleaning.
