Product Overview
Digital Manifolds Like No Others
The SMAN2 and SMAN3 are like no other digital manifolds on the market—they’re the only
manifolds that automatically calculate target superheat, so you don’t have to worry about
guesswork or manual calculations. Plus they’re the only manifolds with the ability to perform
a linear adjustment of the pressure sensors based on refrigerant type, temperature, and
pressure, and it’s so easy, you can do it right in the eld.
With the SMAN3 you also get a built-in micron gauge with resolution from 50 to 9,999. On top
of that, the SMAN3’s exclusive micron alarm allows you to set the alarm to a chosen micron
level, and when the vacuum reaches that level, the alarm will sound, freeing you up to keep
working when pulling a vacuum.
By combining new technology with an intuitive, easy-to-use interface, the SMAN2 and SMAN3
make it easy for you to quickly maximize the eciency of any A/C or refrigeration unit. And
because they’re built by the HVACR industry’s leading innovator, you know it’s packed with
the features you want:
