Tel-Tru™ T-T Dura-Puffer™ produces puffs of smoke on demand for environmental air motion studies. Dura-Puffer offers many of the features of both the classic T-T Smoke Stick and the T-T Smoke Gun combined in a reusable, unbreakable Teflon* dispenser body, which, like glass, is virtually impervious to titanium tetrachloride.

The Dura-Puffer body is 2-3/8" in diameter by 5-1/4" high and is filled with cotton. Replaceable screw-on plastic dispenser spouts add 1-3/8 inches to the height. Note that with use, the plastic dispenser spouts will decay and must be replaced. Two are supplied with each Dura-Puffer kit. A flat Teflon* screw-on cap is also supplied for long term storage of unused smoke between application.

To use the Dura-Puffer, load the contents of a refill vial into the dispenser body and screw-on a dispenser spout. Titanium tetrachloride combines with atmospheric moisture to form dense, persistent smoke. Smoke is emitted in discrete puffs or in a long stream - depending on how the dispenser body is squeezed.

Each refill vial provides from 250 to 500 or more puffs of smoke. The #15-080 kit includes the Dura-Puffer, four refill vials, a storage cap, two dispenser spouts and instructions contained in a handy high-impact plastic carrying case.

Note that titanium tetrachloride is a corrosive. Read all Safety Information before using.
