100 Pack of Splintax packaged in a plastic container with screw-top lid. 10-20 Second burn time smoke emitter matches produce 20 Cubic Feet of White/Grey non-toxic smoke. These smoke
matches provide a quick and inexpensive method of
generating a small burst of smoke. A great product for testing low pressure duct-work systems and also for air balancing. The smoke
emitted does not contain oil nor zinc and will not leave any residue. It is
non-toxic and has the same density as air, so that it is possible to observe
true air movements without the complicating factor of having to allow for the
natural rise or fall of the smoke. The particle size is 0.3 to 2.5 microns making it
ideal to check HEPA filters.
