The fastest and most convenient duct air leakage tester in the industry
Kanomax has developed the most advanced Duct Air Leakage Tester (DALT) for commercial duct systems. It’s designed to be simple to use, accurate, and extremely convenient. The instrument provides step-by-step test configuration and automated leakage testing based on the SMACNA HVAC Air Duct Leakage Test Manual, and is accurate to?±2.5% of reading.?Though built tough with an on-board, powerful motor, the DALT 6900?is very easy to transport on its pneumatic tires and leaves little to no footprint on the job site.
The instrument requires very little training due to the?easy-to-follow, full color HD touch screen display?through which the user can follow the step-by-step process and select from multiple choice configuration options. ?The touch screen also allows the user to quickly toggle between measurement unit outputs like Fahrenheit and Celsius temperature units to m3/s, CFM, l/s, or m3/h airflow units. ? Keeping further?in line with simplicity, this duct air leakage tester does not require the use of orifice plates, which decreases the time required conduct a test as well as the room for error. ?All of the parts that are needed for the leakage tests are already included with the unit, therefore the user will not have to research and order different pieces for different projects. ?The only choice to be made is?between the flow grid and the low-flow nozzle, which are both included and attached to the unit with professional grade, stainless steel cam locks.
The DALT 6900 can also perform both positive and negative (decay) pressure tests with a simple rearrangement of the hose, saving even more time for contractors that deal with a multitude of varying test requirements.

“EB&I purchased the DALT 6900 at the 2016 SMACNA Convention after seeing the demonstrations. We were impressed with the ease of set-up, use, and accuracy of the device and anticipated needing these attributes for some upcoming work. We have since used the machine for those projects and in several other applications where the airflows measured, the accuracy of the reading, and the repeatability of the readings were very important and had to be demonstrated. The DALT 6900 machine worked flawlessly and reliably in all of these situations.
However, in our opinion, the best part of owning and using this machine is the technical support that comes from the Kanomax Team. One of our projects required Kanomax to supply technical data about the machine, and the certification process of the machine, to a degree that is not normally asked for. The Kanomax Team went above and beyond expectations and did this without any hesitation.
I could not be any happier with both the machine and the Kanomax Team.“
