"Actually engineering the flow would make sense. Maybe they need to attach the hood to the pot lid; now there is totally new paradigm.  Air jets blowing upwards around the edge of the cooktop would help also. After all that, there is still a…"

"Even when gas stoves DO have exhaust fans they capture a small % of the combustion products. Note when a boiling pot is on the outside burners, most of the steam bypasses the exhaust hood. Inside burners get more of the exhaust. Even with 250 CFM…"

"on a related note, Exhaust fans flow into a duct that offers 25 Pa of resistance say.  If the house depressurized to -25 Pa as a result of the exhaust fan running the flow would drop by say 50% but would never stop.  Even a Passiv Haus…"

"For in house testing, applications that save the most time and allow for better testing are: 1. Being able to turn your Duct Tester on/or off to look for leaks or to check to see if you've gotten the ducts up to code. You can now operate your…"

Smart gauges will change how we use Blower Doors, DucTesters and other diagnostic tools

The world’s first touchscreen WiFi gauge          Webinar Sept 12/2013 11AM PDT, 2PM EDTThe DM32 controls all blower doors, duct testers, and some flow grids. We’ve even introduced advanced features that will not only modernize just the gauge but the older devices attached to them as well. For example, automatic corrections can be made in the gauge for system backpressure correction when using flow grids.  Control your gauge using any mobile phone, tablet or iPod using iOS (Apple), Android or…See More

Colin Genge replied to George J. Nesbitt's discussion Duct Testing High Velocity Systems

Colin Genge replied to Colin Genge's discussion What is the value of using a pressure pan to test outlets?
"If the cavities are that tight that their pressures don't move in step with the house pressure ( or close to it) their contribution to the result or ability to affect the result in any way are microscopically small to non-existent so you…"
