Introduction
A commercial kitchen grease removal system encompasses all the technologies and components used to capture, separate, and remove cooking grease from the exhaust airstream before it reaches the exhaust ductwork, fan, and external discharge point. Effective grease removal is fundamental to commercial kitchen ventilation safety — grease accumulation in ductwork is the primary fuel source for duct fires, the primary cause of fan bearing failure, and the primary reason kitchen exhaust systems require expensive periodic maintenance. Removing grease as early and as thoroughly as possible in the exhaust airstream protects all downstream components and reduces total system maintenance cost over the ventilation system's life.
Yuede's grease removal system offering spans the full technology spectrum: mechanical baffle filters integrated in exhaust hoods for primary bulk grease separation, electrostatic precipitators for secondary fine particle and aerosol capture, UV treatment for vapor-phase grease decomposition, and automatic cleaning systems for maintaining filter performance without manual disassembly. These technologies can be combined in multi-stage systems where regulatory requirements or operational conditions demand the highest possible grease removal performance.

Application
- Fire Safety Compliance: The primary application of any grease removal system. NFPA 96 (USA), EN 16282 (Europe), and GB 50016 (China) all require grease removal equipment to prevent duct grease accumulation to the hazardous levels that fuel duct fires. Every commercial kitchen is legally required to have an effective grease removal system in the exhaust path.
- Environmental Emission Compliance: China's GB 18483, Hong Kong's Air Pollution Control Ordinance, and equivalent regulations in Singapore, Malaysia, and other Asian markets specify maximum grease and particulate emission concentrations at the kitchen exhaust discharge. Meeting these standards requires grease removal efficiency beyond what baffle filters alone provide — typically requiring ESP as a secondary stage.
- Ductwork Life Extension: Effective grease removal significantly extends the intervals between required duct cleaning — reducing both the cost and operational disruption of duct cleaning programs. In high-rise buildings where duct access is difficult and expensive, effective grease removal at the source is the most cost-effective maintenance strategy.
- Fan Protection: Grease reaching the exhaust fan coats impeller blades, causes imbalance, increases vibration, and accelerates bearing wear. Effective upstream grease removal protects the fan and extends service intervals dramatically.
- Neighbor Relations and Planning Compliance: In sensitive locations, multi-stage grease removal combined with odor control may be required as a condition of planning permission or as a response to neighbor complaints — making the grease removal system a critical element of the business's license to operate.
- Q: What is the minimum grease removal system required for a commercial kitchen?
- A: The legal minimum varies by jurisdiction. In most markets, a mechanical grease filter (baffle type) in the exhaust hood is the code minimum. However, most emission regulations for outdoor discharge also require a secondary electrostatic precipitator or equivalent to meet particulate emission concentration limits. Yuede recommends specifying at least a baffle filter (integrated in hood) plus ESP as a baseline for any commercial kitchen — and adding UV or additional stages where local regulations, cooking load, or neighbor sensitivity require higher performance.
- Q: How much grease does a typical commercial kitchen generate?
- A: Grease generation varies enormously by cooking type. A high-volume wok cooking operation can generate 200–500 grams of grease per hour per cooking station, while a light-menu café may generate 10–30 grams per hour. Yuede's system sizing calculation takes cooking load into account — understanding your cooking equipment list and daily service hours allows correct specification of ESP efficiency tier, filter cleaning frequency, and grease interceptor capacity.
- Q: How do I know if my existing grease removal system is performing adequately?
- A: Key indicators of inadequate grease removal performance include: visible grease deposits on the duct walls within 1 meter of the ESP outlet; visible grease haze or smoke at the exhaust discharge point; grease deposits on the exhaust fan impeller requiring cleaning more frequently than monthly; and complaints of cooking odors from neighbors. Yuede can arrange an on-site assessment including exhaust airflow measurement and visible inspection of downstream ductwork to evaluate current system performance and recommend upgrades.
- Q: Can Yuede supply a grease removal system for a new kitchen design project?
- A: Yes. For new kitchen design projects, Yuede's technical team can work directly with the kitchen designer, MEP consultant, and architect from early design stages to specify the appropriate grease removal system for the project's cooking program, building type, and local regulatory requirements. Early engagement allows the hood sizing, duct routing, and plant room requirements for the grease removal equipment to be integrated into the building design — avoiding the expensive and disruptive retrofits that occur when grease removal is left as an afterthought.
