In every commercial kitchen, cleanliness and safety begin with one crucial system — the kitchen exhaust system. From hawker stalls to central kitchens, exhaust ducts, hoods, and fans work continuously to remove smoke, grease, and heat. But without proper cleaning and maintenance, this essential system can turn into a major fire hazard, cause unpleasant odours, and reduce the efficiency of your kitchen operations.
Our company provides professional kitchen exhaust cleaning and maintenance services in Singapore, ensuring your ventilation system stays safe, efficient, and compliant with NEA (National Environment Agency) and SCDF (Singapore Civil Defence Force) regulations.
Why Kitchen Exhaust Cleaning and Maintenance Is Essential
1. Fire Prevention
Grease buildup inside exhaust ducts and hoods is highly flammable. Over time, layers of oil and grime accumulate in the ductwork, filters, and fan blades. A single spark from cooking equipment can ignite these residues, spreading fire rapidly through the entire exhaust system.
Regular cleaning by certified technicians removes combustible grease deposits, significantly reducing the risk of kitchen fires and ensuring compliance with SCDF Fire Safety Code.
2. Hygiene and Air Quality
A dirty exhaust system affects air circulation, trapping smoke and heat inside the kitchen. It leads to an uncomfortable environment for chefs and staff, while odours can drift into dining areas or neighbouring units. Proper exhaust maintenance ensures cleaner air, reduced heat, and a more pleasant working environment.
3. Regulatory Compliance
Singapore’s NEA and SCDF require commercial kitchens to maintain their ventilation systems according to SS 553:2016 – Code of Practice for Air-Conditioning and Mechanical Ventilation. Failure to comply can lead to penalties, closure orders, or fire safety violations. Our services include documentation and reports suitable for NEA and insurance inspections.
4. System Efficiency
A well-maintained exhaust system runs more efficiently, using less energy to move air. Clean ducts and fans improve suction power, allowing fumes and heat to be extracted more effectively — which reduces strain on your equipment and lowers electricity costs.
5. Prolonged Equipment Lifespan
Grease and dirt can damage motors, fans, and filters, leading to costly breakdowns. Regular maintenance protects your investment and extends the lifespan of your ventilation system.
What Our Kitchen Exhaust Cleaning & Maintenance Includes
We offer a comprehensive service package for all types of commercial kitchens — restaurants, hawker stalls, hotels, food factories, and central kitchens.
1. Exhaust Hood Cleaning
The exhaust hood is the first line of defence against grease and smoke. We deep clean:
- Stainless steel hood surfaces
- Grease traps and baffles
- Interior plenum and corners
- Fan collars and hood frames
Our team uses industrial-grade degreasers and high-pressure washing to remove tough grease deposits, restoring the shine and cleanliness of your hood.
2. Filter Cleaning and Replacement
Filters capture most of the grease before it enters the duct system. We:
- Remove and soak filters in heated degreasing solution
- Pressure wash to eliminate all residue
- Replace damaged or corroded filters
- Inspect filter seals to prevent leakage
Regular filter maintenance ensures smooth airflow and reduces the risk of oil dripping or fan overload.
3. Duct Cleaning
The exhaust ductwork carries fumes from your hood to the discharge outlet. This section is prone to hidden grease accumulation and must be cleaned using specialised tools and methods.
We perform:
- Internal duct inspection using cameras or access panels
- Rotary brush and foam cleaning system
- Hot water pressure rinsing
- Full degreasing of horizontal and vertical ducts
- Final inspection to confirm cleanliness
Every duct cleaning is documented with before-and-after photos for compliance records.
4. Fan and Motor Cleaning
The exhaust fan provides the suction that drives your ventilation system. Our technicians clean and service:
- Fan blades and housings
- Motor bearings and belts
- Vibration dampers
- Electrical connections and insulation
We ensure the fan operates quietly and efficiently, extending its service life and preventing breakdowns.
5. Odour Control System Maintenance
For systems with electrostatic precipitators (ESP), carbon filters, or UV ozone units, we:
- Clean ESP cells and collector plates
- Replace activated carbon media as needed
- Inspect and service UV lamps and power supplies
These steps ensure your odour control units continue to meet NEA environmental emission standards.
Recommended Cleaning Frequency
The ideal cleaning frequency depends on your cooking type and kitchen workload. Based on our experience and local regulations:
| Type of Kitchen | Cleaning Frequency |
|---|---|
| High-volume (Hawker, Central Kitchen, BBQ, Wok) | Every 1–3 months |
| Medium-volume (Restaurant, Café, Catering) | Every 3–6 months |
| Low-volume (Bakeries, Light Cooking) | Every 6–12 months |
We also offer custom maintenance contracts with scheduled visits to keep your system in top condition all year round.
Step-by-Step Cleaning Process
- Site Inspection and Preparation
We inspect your system layout and identify grease access points. Protective covers are placed over kitchen equipment and flooring to prevent contamination. - Access Panel Opening and Isolation
Access panels are opened to reach the internal ductwork. Fans and electrical systems are safely isolated before cleaning. - Hood and Filter Degreasing
All filters are removed for deep cleaning. The hood is scrubbed with a food-safe degreaser to remove surface oil and soot. - Duct Interior Cleaning
Using rotary brushes, foam injectors, and high-pressure rinsing, our team removes built-up grease throughout the duct length — from hood to fan. - Fan and Motor Cleaning
The exhaust fan is dismantled and cleaned thoroughly. Bearings and belts are inspected and lubricated if necessary. - Odour and ESP Unit Servicing
For systems with odour control, ESP plates are cleaned, carbon filters replaced, and UV systems checked for efficiency. - Final Inspection and Testing
Once cleaning is complete, we reassemble all components and test airflow performance. A visual and photographic report is provided for recordkeeping. - Certification Issuance
We issue a Cleaning & Maintenance Certificate, including date, method, and technician details — suitable for NEA, SCDF, and insurance submission.
Why Regular Maintenance Matters
Neglecting kitchen exhaust cleaning can lead to serious issues that affect your safety and business continuity:
- Fire hazards due to grease ignition.
- Odour complaints from neighbouring units or customers.
- Reduced airflow, causing hot and smoky kitchens.
- Fan failure due to excess load and vibration.
- Non-compliance penalties from NEA or SCDF.
With our scheduled maintenance program, you can prevent these problems before they happen — saving time, money, and potential legal trouble.
