“I have an $800 diffuser to sell you.” “Hello?” Some discussions end before they begin. On the subject of designing around electronic VAV diffusers, the discussion is usually over before it starts. No problem. 15X the cost of something that works is a challenge for...
Our next training session is about room comfort. Upcoming posts will more directly address that topic. Meanwhile, I notice that 60 Minutes has a piece on HVAC and air quality. The piece aired Sunday, October 29th and was called ‘The Air We Breathe’. Oh my gosh, our...
The engineers behind CookSelect software made it so easy to use, even a caveman could use it. When it’s time to spec air movement, you know what’s required of the job. What you need is fast fan selection and easy scheduling exports. CookSelect allows you...
How many of you have purchased a single car brand your entire adult life? None. (Yeah, there’s one or two of you. Still using a paper catalog, too.) Is one fan significantly different from another? Not really. If you can point out a consequential difference,...
One thing about our industry. No one cares much about ‘better’. If there isn’t a problem to solve, no one has time. If there IS a problem to solve, we’re all looking for a solution. When Air Flow introduced Price’s chilled beams to the market in 2010, the point was...
PART 1, Lesson Learned. When I got into selling and fabricating Thermaduct and Koolduct, I forgot an important business principle. It’s a bad idea to turn a customer into a competitor. I thought, for starters, that contractors don’t like the responsibility of...
I have to admit, the panel radiator is a slick product, and Air Flow doesn’t offer it. *Sigh*. Compared to the ‘base’ design of 220F water and 70F space, a panel radiator derates when the space temp is warmer or the water supply temperature drops. For example,...
Aaron Rodgers and I talk all the time. We’re old pals. Now you know. While I can’t quote him directly, I asked him what he’d be doing in his spare time over the next year. Aaron is concerned about climate change and wants to understand how to design the HVAC for a...
When I explain dust collection to newcomers at Air Flow, I just say it’s a big vacuum cleaner. It’s true. There’s a fan and a capture device. A cyclone dust collector is like a bagless vacuum cleaner. A shaker is a lot like the vacuum shown above, except the shaker...
When the authority having jurisdiction on NFPA dust collector safety regs asks you what you know about code, do you want to wing it? Or do you want to answer confidently? Unless you’re a very experienced dust collector pro, you’re probably not prepared for that...
