The Tempest Variable Speed Blowers are the most powerful electric blowers, size-for-size, on the market today. Capable of blade speeds up to 3,200 RPM, the variable speed blowers feature low startup amp surge and will run on generators as small as 2,000 watts. The 16 inch variable speed blowers offer the best combination of compact size and powerful air movement. It is ideal for PPV of smaller structures, firefighter rehab, or traditional NPV operations. The 18 inch variable speed is a versatile blower that can be used for small to medium sized PPV operations. Its compact design will fit inside most apparatus compartments and the 18 inch diameter shroud can easily seal a standard doorway for effective PPV. The 21 inch variable speed blower is the ideal alternative to gasoline powered PPV blowers. It is large enough to ventilate most residential structures and can be operated at slower speeds for overhaul or firefighter rehab. See chart for details.
