Hawker centres are the heart of Singapore’s food culture — vibrant, busy, and filled with the aroma of local delicacies. But behind every sizzling wok and steaming pot lies one critical system that keeps the entire kitchen safe, clean, and comfortable: the hawker kitchen exhaust system.
At our company, we specialise in designing, installing, cleaning, and maintaining hawker kitchen exhaust systems that meet the highest standards of safety, hygiene, and efficiency. Whether you operate a single hawker stall or manage multiple stalls in a large food centre, our team ensures that your exhaust system works flawlessly — keeping smoke, grease, and odour under control while meeting NEA and SCDF regulations.
What Is a Hawker Kitchen Exhaust System?
A hawker kitchen exhaust system is a mechanical ventilation system designed to remove smoke, steam, odours, grease, and heat produced during cooking. In hawker environments, where wok frying, grilling, and deep-frying are constant, the exhaust system plays a crucial role in maintaining air quality and preventing fire hazards.
A typical setup includes:
- Exhaust hoods mounted above cooking equipment to capture smoke and grease vapours.
- Grease filters that trap particles before they enter the duct.
- Ducting systems that channel fumes to an outdoor discharge point.
- Exhaust fans that create negative pressure and maintain airflow.
- Odour control units or ESP filters (electrostatic precipitators) for environmental compliance.
For Singapore hawker centres — which often have shared exhaust ducts and centralized ventilation — proper design, installation, and maintenance are key to preventing backflow, blockages, or fire risks that can affect multiple stalls.
Why Hawker Kitchen Exhaust Systems Are So Important
1. Fire Safety
Cooking oil vapours and grease accumulate over time inside ducts and filters. Without regular cleaning, this buildup becomes a fire hazard. A single spark from a stove can ignite the grease layer inside the ductwork, leading to dangerous fires that spread quickly.
Our systems are designed and maintained to comply with Singapore Civil Defence Force (SCDF) fire codes. We use fire-rated ducting materials, high-efficiency filters, and ensure proper clearances to minimize risk.
2. Hygiene and Air Quality
In a hot, compact hawker kitchen, poor ventilation leads to uncomfortable working conditions and lingering smoke that affects both hawkers and customers. Proper exhaust ventilation ensures cleaner air, reduced heat, and better hygiene by preventing grease deposition on walls and ceilings.
3. Compliance with NEA and Building Requirements
Singapore’s National Environment Agency (NEA) and local town councils impose strict ventilation and odour control requirements for hawker stalls. Our exhaust systems are fully compliant with NEA guidelines and designed to handle continuous, high-temperature operations typical of hawker kitchens.
4. Odour Management
Hawker centres serve hundreds of meals daily — and without odour management, exhaust fumes can become unpleasant for diners. Our systems can integrate activated carbon filters, UV ozone odour removal, or ESP scrubbers to neutralise odours before air is released outdoors.
5. Extended Equipment Lifespan
A well-maintained exhaust system prevents grease and soot buildup on cooking equipment, extending its lifespan and reducing maintenance costs. Regular servicing keeps your fans, ducts, and filters functioning efficiently year-round.

- Proper sealing and balancing of air pressure
- Integration with odour control or scrubber systems
All installations are carried out by trained technicians familiar with hawker centre infrastructure and safety codes.
3. Exhaust Cleaning and Maintenance
Hawker kitchens produce large volumes of oil and smoke daily, which means exhaust systems must be cleaned regularly to prevent grease buildup. Our cleaning service ensures that your system stays safe, efficient, and compliant.
We provide:
- Deep hood and filter cleaning
- Internal duct degreasing using rotary brushes and foam cleaning
- Fan and motor cleaning to improve airflow
- Odour control and ESP unit servicing

- Retrofitting old systems to meet updated fire codes
We also help hawker stall owners convert outdated or non-compliant systems into modern, energy-efficient solutions that meet the latest standards.
NEA and SCDF Compliance
Compliance is non-negotiable for any hawker kitchen. Both NEA and SCDF have specific requirements for ventilation, grease control, and exhaust discharge. Our team has extensive experience working with government agencies and can ensure your system meets all regulatory requirements.
Key compliance areas include:
- SS 553:2016 Code of Practice for Air-Conditioning and Mechanical Ventilation
- Fire Code (SCDF) – fire-rated ducts, fan enclosures, and proper clearances
- Environmental Health Regulations (NEA) – odour and grease discharge standards
- Town Council maintenance contracts – approved inspection and servicing records
We also assist in preparing as-built drawings, certification letters, and maintenance logs required by authorities.
Common Issues in Hawker Kitchen Exhaust Systems
Even well-built exhaust systems can encounter problems over time due to heavy daily use. Common issues include:
- Reduced suction power – often caused by grease-clogged filters or blocked ducts.
- Excessive noise or vibration – usually due to worn fan bearings or unbalanced blades.
- Oil leakage – improper duct gradient or grease trap malfunction.
- Backflow of smoke – negative pressure or shared duct issues in multi-stall setups.
- Odour complaints – insufficient filtration or failing scrubber units.
Our diagnostic service identifies the root cause and provides practical solutions, whether through cleaning, component replacement, or system redesign.
Cleaning Frequency and Maintenance Schedule
For hawker stalls, regular cleaning is crucial because of heavy oil usage and high cooking temperatures. Based on our experience and NEA guidelines, we recommend:
