Air Flow’s upcoming class Industry Testing Standards of HVAC Equipment (AMCA, AHRI, AMCA Sound) is going to spend some time on silencers. Why? The numbers insertion loss and pressure drop data is important. But more important is how the numbers were arrived upon. ...
That’s a dandy of a question. It depends on the problem you are trying to solve. LINT: Price can accommodate a standard VAV box with an orifice ring instead of a cross flow sensor. Take the static pressure on both sides of the ring, know the opening size of the...
Just a few weeks ago, I posted that it had been 25 years since I became the ‘new’ owner of Air Flow Inc. If you’ve followed any of our social posts and videos, you know that founder Al Gelin passed away in a plane crash in 1995, and founder Neil Drees from cancer in...
I thought I was alone on the quest to research and teach folks about duct and system leakage. Turns out I’m not alone. Meet Mark Mahon, Business Development Manager for Price Industries and all-around great guy. (Nerdiness never prevented likeability, did it?) A...
“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...

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,...
Let’s talk briefly about track records. How many Operating Rooms have we worked with on Ultrasuite? More than 30. How many has Price sold nationwide? Roughly 350. You probably want to know “what’s driving that?” I can think of two factors. DESIGN Other companies offer...
Price’s integrated Operating Room System, Ultrasuite, is infuriating this doctor. His hobby is a strange one. He loves making animal shadows in the light of the boom. Price’s Ultrasuite, as you know, integrates the lights into the diffusers. It does such a fine job,...
I’M STUMPED Look, everyone hates a sound problem after a project is wrapped up. But ignoring acoustics on the front end isn’t the right path. Why would you roll the dice, either by leaving silencers off your plan, or not getting reliable support? YOUR...
