TEC Fog Puffer™ Kit

TEC Fog Puffer™ Kit A simple, cost-effective way to make air leakage visible. The TEC Fog Puffer™ Kit from The Energy Conservatory is designed for weatherization, home performance, energy auditing, and other building-performance professionals who need a practical way to locate air leaks. Originally developed by Gary Nelson, the Fog Puffer™ provides a controlled source of visible fog that can be used to trace air movement and help identify leakage paths in residential buildings. The Fog Puffer™ uses Propylene Glycol (PG) to create the fog and is designed to consistently deliver the small amount needed for common residential air-leak diagnostics. Why Use a Fog Puffer? See air movement — visible fog makes otherwise invisible air movement easier to identify. Locate leakage paths — use it to investigate suspected air leaks throughout the building envelope. Great for blower door testing — use pressure diagnostics to find that a building leaks, then use fog to help determine where. Compact and portable — easy to carry as part of a home-performance or weatherization test kit. Cost-effective — an economical source of fog for everyday residential diagnostics. Refillable — cartridges can be refilled using the supplied Propylene Glycol and filling bottle. Ideal For Blower door testing Energy audits Weatherization work Home performance diagnostics Air-sealing verification Locating building-envelope leakage paths Investigating air movement around penetrations and other suspected leaks How It Works Fill a cartridge with the supplied Propylene Glycol, attach the cartridge to a charged battery, and install the assembly into the modified baster. A puff from the baster activates the Fog Puffer™ and produces visible fog that can be released near a suspected leakage area. When used during building-pressure diagnostics, watch how the fog moves to help identify where air is entering or leaving the structure.
