Features and Benefits:Powerful Makita-built motor delivers 127 CFM and 96" water lift of suction using corded power;Powerful Makita-built motor delivers 74 CFM and 36" water lift of suction using two 18V LXT® Lithium-Ion batteries;Up to 65 minutes of continuous run time on low setting and 30 minutes on high setting using two 18V LXT® Lithium-Ion 5.0Ah batteries BL1850B;Efficient three stage HEPA filtration system captures 99.97% of particulates .3 microns and larger extending the life of the main filter;Filter cleaning system is designed to maintain optimum suction efficiency and longer filter life;Precision lightweight motor components and efficient air ducting produce a vacuum weight of only 21.8 lbs with batteries;Oversized on-off switch for operator convenience;Motor chamber constructed of quality sound-absorbing materials for quiet operating sound levels;75 dB(A) using corded power and 64 dB(A) using battery power;Variable speed control dial for a variety of applications;In cordless operation, the Dry Dust Extractor/Vacuum is powered by two 18V LXT® batteries for 36V power and run-time, without leaving the 18V LXT® battery platform. Using two 18V 5.0Ah batteries, the Dry Dust Extractor/Vacuum delivers up to 65 minutes of continuous run time on low setting and 30 minutes on high setting. The powerful Makita-built motor delivers 74 CFM and 36” water lift of suction on battery operation. In corded operation, the vacuum delivers 127 CFM and 96” water lift. The 19.7' power cord combined with the anti-static hoses (1-1/2" x 8' or 1” x 11-1/2', both included) provide extended reach for fast clean-ups. The Dry Dust Extractor/Vacuum has a 3-stage filtration system engineered for efficient cleaning and to extend the life of the main filter. The system consists of a Pre-Filter Bag (captures larger dust particulates), Damper Filter (captures much smaller particulates) and Main Filter (captures micro particles). All three filter components are included. The Dry Dust Extractor/Vacuum is loaded with ease-of-use features, such as an oversized on-off switch, variable speed control dial, and dual L.E.D. battery indicators are clearly visible and easily accessible on the top and front of the vacuum. Additional features include quick-release metal latches, large rubber bumper, and rear casters with locking levers.
