Grease and oil buildup in kitchen exhaust ducts is one of the leading causes of fire in commercial kitchens.

For large-scale food courts with dozens of cooking stations running simultaneously, this risk multiplies — and standard filtration often isn’t enough.

The Challenge

A shopping mall in Hanoi operates a food court with 40 restaurant stalls and a combined kitchen capacity of 1,800 kW. With that many stations running grills, fryers, and woks throughout the day, grease-laden vapor accumulates rapidly inside the exhaust ductwork. This buildup posed a serious fire hazard, required frequent and costly duct cleaning, and risked violating fire safety (PCCC) regulations.

Air Filtech’s Solution

Air Filtech supplied and installed CamClose grease filters, which use cyclonic separation technology to capture oil and grease particles before they reach the ductwork. Instead of relying on a filter medium that traps grease (and needs frequent replacement), the cyclonic design spins the airflow to separate out grease droplets by centrifugal force, channeling them into a collection reservoir rather than letting them coat the duct interior.

Results After 6 Months of Operation

  • Grease buildup inside the ductwork reduced by 85%
  • Duct cleaning frequency extended from every 3 months to once every 12 months
  • Cost savings of approximately 60 million VND per year
  • Zero fire incidents recorded
  • Full compliance confirmed with fire safety (PCCC) regulations
