Maintenance records demonstrate normal operation, cleaning intervals and fault handling, making responsibility clear during complaints or inspections.

Multiple burners in one kitchen can share a unit based on total airflow and simultaneous use; different businesses should usually not share because re

First inspect burners, hood, airflow, ducting, power supply, fan static pressure and discharge point, then decide whether to replace the purifier or m

Outdoor installations need rain, sun and freeze protection plus service access; the power and control boxes must have suitable ingress protection, and

Key commercial areas, large restaurants or regulated locations can use online monitoring to track purifier status, operation, emission data and mainte

A pressure gauge indicates filter or cell blockage, and a sustained rise usually signals cleaning or maintenance, helping prevent reduced fan performa

Replace it when odor breakthrough occurs, the carbon gains noticeable weight, pressure difference rises or the service interval is reached; heavy-fume

Lamp effectiveness declines with use, and a lamp that still lights may no longer control odors adequately; replace it according to the service interva

A brief light smell may occur with UV or oxidation modules, but persistent irritating odors in occupied areas indicate possible problems with reaction

Common causes include short circuits, current leakage, damp cells, heavy grease, power-module faults or abnormal grounding; switch off and inspect rat

Arcing may be caused by heavy grease, deformed plates, foreign objects, damp insulators, abnormal cell spacing or high-voltage power-supply faults. If

Switch off the power, remove the cells, soak them with a suitable degreaser, clean with a soft brush, rinse and dry thoroughly, then check insulators,

Grease buildup lowers efficiency, increases resistance and fan load, and may cause arcing, odors, breaker trips or even fire risk. If performance drop

Ordinary mechanical or electrostatic purifiers mainly remove oil droplets and particles and have limited odor effects; UV, ozone oxidation or activate

No. Absence of visible smoke only shows that some particles are not obvious; GB 18483 still requires emission concentration and removal efficiency, an

Possible causes include wet plates, poor sealing, mismatched airflow, improperly reinstalled cells, leaky ducts or a faulty fan. After cleaning, confi

Most designs place the purifier on the fan inlet side so the fan handles relatively clean air; the exact position depends on ducting, fire dampers, ma

Single-stage units are simple and low-cost for light fume loads, while multistage combinations of mechanical, electrostatic and odor treatment suit he

The hood captures fumes, the purifier treats them and the fan provides airflow and static pressure; all three must be matched to the same airflow, res
