Features & Applications:

The Powder Puffer Smoke Source is an inexpensive, non-toxic alternative to other air current detectors. This easy to use bottle will generate about 200 puffs of safe and inexpensive "smoke" for use in many applications, including checking drafts in fume hoods, ducts, registers or at windows and doors. You can also use the Powder Puffer to visually monitor air balancing, wind direction and air movement to ensure that combustible by-products are going where they belong.
