Mechanical ventilation and exhaust systems are critical components in any commercial kitchen, ensuring compliance with Australian standards and maintaining a safe, efficient cooking environment. According to AS 1668, proper ventilation is essential for removing airborne particles, fumes, smoke, steam, and vapours from the premises, thereby preventing contamination of food and maintaining air quality.
Effective ventilation serves two primary functions: introducing fresh air and expelling cooking vapours and fumes. While air-conditioning can provide comfort to staff, it is not a substitute for proper ventilation. Without a fresh air system (make-up air), air-conditioning alone is not sufficient for maintaining air quality in a commercial kitchen.
Common Ventilation Issues
Poorly designed or inadequate exhaust systems can lead to several problems:
Natural ventilation methods, such as open shop fronts or windows, are generally insufficient for kitchens that engage in substantial cooking, especially with gas. Mechanical exhaust systems are essential for effective ventilation, and their installation should be completed before the kitchen becomes operational to avoid costly and disruptive retrofits.
All components of a mechanical ventilation system—fans, kitchen exhaust hoods, and ductwork—must adhere to the Australian standard AS 1668.2-2012. Existing systems installed before 2012 are not required to be upgraded unless they fail to meet current standards. Indicators of an inadequate system include grease deposits on surfaces and flaking paint due to condensation. In some cases, updating or extending the canopy or replacing the fan may resolve these issues.
At PCK, we emphasize the importance of selecting high-quality materials for exhaust systems. Stainless steel is our preferred choice due to its durability and ease of cleaning, despite its higher cost. While galvanized steel may be a less expensive option, it is harder to clean and less aesthetically pleasing. For ductwork and risers, galvanized steel is acceptable as it is often concealed.
Special Considerations for Wood-Fired and Charcoal Systems
Since 2012, regulations for wood-fired and charcoal systems have become more stringent. These systems now require standalone exhaust systems with dedicated ducting and risers extending to the rooftop. The new standards aim to enhance safety and prevent fire hazards.
Australian councils mandate that charcoal and wood-fired systems adhere to a ‘zero emission’ policy. This requires the elimination of all smoke, vapour, and odours using advanced filtration methods such as electrostatic filters (ESP), ozone generators, UV filtration, or other approved technologies. At PCK, we collaborate with specialist suppliers who design custom canopies and filtration systems to meet these rigorous standards.
