Peak boiler season runs September through November. For HVAC contractors on commercial routes, this is the highest-demand window of the year — and the one where equipment failure costs the most.
The Sootmaster® 652M was built for this window.
5.25 gal steel tank. Built for commercial HVAC and oil boiler work, 1–2 large jobs a day.
UL Listed, required on some commercial contracts.
Running residential chimney sweep routes with 3–4 jobs a day? The Sootmaster® 641M (3.5 gal) is built for that route. Same 1 HP motor. Same 94 CFM.
Built in Newburgh, NY. American manufacturing.
The machines your crew uses from October through February need to be the right machines. Not substitutes.
