LK-E Series Commercial Kitchen Electrostatic Precipitator
The Polygee LK-E Series is an engineering-grade in-duct ESP platform for restaurant, hotel, food-court and chain-kitchen exhaust purification. Featuring dual-zone plate-type electrostatic field technology and drawer-style washable collector cells, it delivers 90%–98% filtration efficiency for grease, smoke and oil mist removal. Available in three grades — LK-E0 (≥90%), LK-E1 (≥95%) and LK-E2 (≥98%) — with airflow from 3,000 to 40,000 m³/h, low 23–34 Pa pressure drop, and an optional ESP + UV + CB odor-control upgrade.
Free Modular Combinations
LK-E modules stack and combine freely to match airflow, space and odor-control needs — single unit, multi-layer stacking, horizontal arrays, and ESP + UV + CB systems.

Why Commercial Kitchens Need ESP Purification
Cooking Fumes Are a Serious Health & Safety Risk
Kitchen exhaust contains grease particles, PM2.5, VOCs, and carcinogenic compounds that cause respiratory issues, lung damage, and weakened immunity for kitchen staff. Grease accumulation in ductwork is also the #1 cause of commercial kitchen fires.
Regulatory Compliance Is Mandatory
Cities worldwide enforce strict emission standards for commercial kitchens. Failure to comply results in fines, forced closures, and lawsuits from neighbors. An LK-E ESP system is the most effective way to meet EPA, EU, and local regulations.
- Eliminates 90–98% of grease, smoke, and oil mist
- Prevents grease buildup in ductwork — reduces fire risk
- Meets EPA, EU, and local emission regulations
- Protects kitchen staff from harmful fume exposure
- Eliminates neighbor complaints about smoke and odor
- Washable cells — no disposable filter waste

Principle of Electrostatic Purification
Each LK-E grade uses a multi-stage purification process. Select a series below to view its purification principle.
Airflow Distribution
Washable mesh pre-filter traps large particles and evenly distributes airflow.
→Primary Ionization
High-voltage ionization charges grease and smoke particles.
→Plate Collection
Dual-zone plate-type collector captures charged particles.
→Secondary Collection
Additional collection capacity for high 98% capture of dense smoke.
→UV + Carbon Polish
Optional UV-C and activated carbon decompose and adsorb residual odors.
Why Dual-Zone Plate-Type ESP as Primary Filtration
Prolonged Wash Cycle & Longer Life
The plate-type design with wider electrode spacing enables higher voltage tolerance, heavier pollutant accumulation, and more rigorous cleaning cycles — extending operational life significantly.
Higher Collection Efficiency
The dual-zone plate-type structure provides maximized collection surface area with uniform electrode spacing, ensuring higher electric field intensity and superior grease capture — even under extreme cooking loads.
Dual-Zone Ionization & Collection
Energized by a self-developed high-voltage power supply, the dual-zone plate-type ESP cells deliver highly-efficient primary removal of oil, grease, and smoke particles from kitchen exhaust air.
Easy Maintenance & Cleaning
Drawer-style collector cells slide out for cleaning. Soak in alkaline degreaser or run through a commercial dishwasher. Fully washable and reusable — zero disposable filter cost.
ESP Cell & Intelligent Power Supply
Self-developed core components — the dual-zone plate-type electrostatic field and the digital power pack — for stable, efficient LK-E operation.
