What is the difference between single pass and double pass kitchen electrostatic precipitator?

Single-pass and double-pass DR. AIRE commercial kitchen electrostatic precipitators (ESPs) differ mainly in configuration, removal efficiency, and application suitability.In a single-pass ESP, exhaust air passes through one ionizing and collection stage only once. The design is simple and compact, typically achieving 90%–95% grease and particulate removal efficiency under optimal airflow conditions. It is best suited for high-level rooftop discharges or locations with moderate regulatory requirements, offering lower cost and easier installation.In contrast, a double-pass ESP routes air sequentially through two stages in series. This configuration significantly boosts efficiency to 98%–99.9%, minimizing pollutant breakthrough even under heavy grease loads. Double-pass systems are ideal for low-level exhaust, strict environmental regulations, and sensitive urban or mixed-use buildings.While double-pass units incur higher pressure drop, larger space needs, and increased maintenance, they provide superior long-term performance and compliance. Single-pass systems are more economical for standard applications.In summary, single-pass ESPs are preferred for cost-sensitive, less critical installations, whereas double-pass ESPs are recommended when maximum air purification is essential. Selection should consider airflow volume, contaminant load, and local codes.
