DustBot 300 HEPA Vacuum produces 300 CFM for efficient dust collection when grinding, cutting or sanding comcrete, masonry, fiberglass and other construction materials, This workhorse vacuum has a 20 gallon capacity and goes through long intervals before filter cleanings, Unlike competitive vacuums, this unit can be run off of 120 volt, It produces 300 CFM and features a 20 gallon drum that is easily removed for emptying, Contractors like how the unit is price considerably lower than competitive HEPA vacuums and can be powered by the onboard 3000 watt generator or standard 120 volt current, This workhorse vacuum has fewer moving parts, and no solenoids, to require less maintenance and provide more reliable performance, The AirBlast filter cleaning system can be actuated while the vacuum is running, without interrupting work; and AirBender technology enables contractors to go up to 10 times longer between filter cleanings, How the DustBot extends cleaning intervals 10 times longer: AirBender technology greatly increases cleaning intervals by doing a superior job of capturing dust Before it reaches the HEPA filter, The AirBender cyclone captures 98 of airborne dust compared to typical cyclones, which capture only 80, How AirBender technology works: The AirBender cyclonic system bends the air stream at the bottom of the canister, and allows 98 of the dust to settle in a large Passive Air Zone before the air moves on to the HEPA filter canister, By allowing only 2, instead of 20, of the dust to reach the HEPA filter, AirBender technology enables contractors to go 10 times longer between cleaning intervals, DustBot 300 delivers far greater productivity, The best way to get high productivity out of any HEPA vacuum is to keep the filter clean, That doesnt mean pulsing every 15 seconds to blow dust off the pleats, It means keeping dust away from the HEPA filter to begin with, That is the way the DustBot300 HEPA Vacuum, with AirBender technology, increases productivity, The truth about pulse cleaning: Pulse cleaning every 15 seconds is hard on HEPA filters, Violent bursts of air explode thrusting abrasive granules against the delicate filter material, damaging the microscopic fibers and shortening the HEPA filters life, DustBot vacuums are much kinder to your HEPA filters, requiring pulsing 1, instead of, 240 times each hour, Why the DustBot requires less maintenance: The moving parts associated with automated pulsecleaning systems solenoids are subject to frequent breakdowns, DustBot vacuums have no solenoids only mechanical switches proven to be reliable when exposed to constant vibration, dust and other harsh conditions, Fast and easy cleaning: Simply pull and release the AirBlast handle to blastclean the HEPA filter, A handy console gauge tells you when airflow is dropping and it is time to blastclean, Typically, once or twice a day does the trick, and it can be done without stopping work, In the heaviest dust creating applications, once an hour may be required, Its fast; its simple, and its more gentle on your HEPA filter, Motor: 2, 1 HP Tangential bypass with 25 cord, Power: 1560 watts, Voltage: 120v 5060hz, Amperage: 13 amps, Generator: 3000 watt, commercial grade Honda GX160 engine optional, Water lift: 70 in, CFM: 312 CFM w 3 orifice, Peakamps: 13 amps, 15, 5 peak, Watts: 1753, Noise level: 79 DB, Stage Motor: 1 stage motor 120V, Filter: 31, 19 SQFT, Efficiency Rating: 99, 97 Efficient 0, 3 Micron, Filtration: Certified HEPA rated 99, 97 , 3 micron with AirBender Cyclone, Hose: One 2, 5 x 25 standard, 3 x 25 hose optional, 3 x 11 for early entry saw optional, Rack for generator, AirBender onboard cyclo SKU: DTLS093
