Hey, it’s your birthday! Go ahead and inhale those candles out! What? You don’t suck the flame off the candle? Have you ever tried? Yes, it’s a silly anecdote and a very effective one (thanks, Dr. Livchak!). As most of us know, we blow out our candles. The physics works well and accomplishes the job […]
As commercial kitchen ventilation systems become more technically complex to satisfy increasingly strict code requirements and environmental standards, coordinating the overall design with the mechanical engineer becomes critical. There was a time when the foodservice consultant whose scope is traditionally below the kitchen ceiling and the mechanical engineer whose interest is above the ceiling worked […]
If you are involved with the design or building of food service properties, then you have probably heard of Pollution Control Systems or Units, or PCU’s for short. A PCU is a system of special filters to help clean grease, smoke and odors from the exhaust air stream of commercial kitchens and restaurants. Do you […]
What is ASTM F1704 Standard Test Method for Capture and Containment Performance of Commercial Kitchen Exhaust Ventilation Systems? How does it differ from U.L. 710 rating?
Simply put, the UL 710 Standard for Safety Exhaust Hoods for Commercial Cooking Equipment criteria is a fire safety test and the ASTM F1704 Standard Test Method for Capture and Containment Performance of Commercial Kitchen Exhaust Ventilation Systems is a performance based test to determine the capture and containment threshold for any given hood under […]
