Technical answers to common questions about kitchen exhaust.
The aluminum collector cells in a kitchen ESP must be removed and soaked in a highly alkaline degreasing bath every 1 to 4 weeks depending on the cooking volume. If the collector plates become heavily insulated with grease, they cannot generate the magnetic field required to capture smoke.
Grease leakage on the roof indicates a failure of the fan's integrated grease trap, or the use of a standard ventilator instead of a UL-762 rated upblast exhaust fan. Upblast fans feature a fully welded, leak-proof base and a discharge spout designed to safely route grease into a collection box.
