Kitchen Fume Purifier

The Kitchen Fume Purifier is installed between the kitchen exhaust hood and the air-moving equipment. It is used to process cooking-fume particles, exhaust air, and part of the odor generated during commercial food preparation.

Available product types include electrostatic fume purifiers, low-level discharge purifiers, and UV purification boxes.

An electrostatic model uses an electric field to capture fine oil-mist particles. A low-level discharge model is intended for installation conditions where the discharge position is relatively low or the surrounding environment requires additional attention.

A UV purification box may be used as a further treatment stage for part of the cooking odor and organic material. The appropriate model should be selected according to the restaurant size, cooking-fume load, installation position, and discharge environment.

The purifier should be designed together with the exhaust hood, fan, cabinet fan, and ductwork rather than treated as an independent appliance.

The available treatment airflow is approximately 2,000–60,000m³/h. Treatment methods include electrostatic adsorption, mechanical filtration, UV photolysis, or combined processing.

The selected airflow must match the collection volume of the exhaust hood, the capacity of the exhaust fan, and the duct system. An undersized unit may not match peak cooking demand, while an oversized unit does not guarantee that the complete system will operate correctly.

Equipment resistance affects the fan and the final airflow. Buyers should obtain the measured pressure drop for the selected configuration and consider it together with the available fan pressure.

A Kitchen Fume Purifier using electrostatic modules requires a corresponding high-voltage power supply. A product using UV treatment modules requires a suitable UV control system.

Available installation methods include indoor suspended installation, floor-standing installation, and outdoor weather-resistant installation.

The correct method depends on equipment weight, available maintenance space, duct direction, and the site environment. Sufficient access should be retained so modules and internal components can be inspected and cleaned.

Electrostatic products can use modular electric fields and access doors, allowing internal modules to be removed for maintenance. Low-level discharge products may use a higher-density or multi-stage configuration according to the confirmed solution.

A UV box can be included as an additional stage in a combined system. All models require regular cleaning based on actual grease accumulation. Insufficient maintenance can affect equipment condition and increase system resistance.
