CleanFreak 21" Ultra High Speed (UHS) Propane Floor Burnisher - 2,000 RPM

Description

CleanFreak 21″ Ultra High Speed (UHS) Propane Floor Burnisher – 2,000 RPM – CPL-PE400BU-21-CF

This CleanFreak 21 inch propane floor burnisher will polish commercial floors to an extremely high shine when used with the correct floor polishing pads. The 18HP, 603 cc Kawasaki engine will turn a pad at 2000 RPM for maximum floor polishing performance. This machine is one of our top performers and you can’t beat the price! Comes backed by a 2 year warranty on the engine and 1 year on parts and labor.

Each CleanFreak propane burnisher comes equipped with SAFR™ (Steady Air to Fuel Ratio) technology which is a system that monitors the pressure between the air filter and the carburetor. As the air filter becomes dirty, the pressure decreases. With this included SAFR technology, the variation in pressure results in a reduction in fuel delivered to the engine. The result is a Steady Air to Fuel Ratio no matter what condition the air filter is in. Not only does this machine perform better than the competition, but it also saves you money by using 34 percent less fuel while requiring 40 percent fewer oil changes.

**Please Note: Just because this machine comes standard with SAFR technology does not mean you never have to clean the air filter. We always recommend cleaning the air filter before each and every use for maximum performance from your floor burnisher.

If this machine is not exactly what you’re looking for, please take a look at our full line of propane, electric and battery burnishers.
