Here’s a novel idea — a vacuum specifically designed to suck it up for the concrete industry.
Concrete dust is the most difficult kind of dust to vacuum, says Travis McCutchen, vice president of sales and marketing at CDCLarue Industries Inc. The gritty powder spewed during saw cuts can clog a typical vacuum’s filter in 15 minutes, faster than wood or drywall dust does. “It’s very abrasive, it’s very fine and it’s hard to contain,” he says.
CDCLarue’s Pulse-Bac Industrial Vacuum & Dust Collector will remove and contain that dust without constant clogs or lagging lift.
The machine features a patented valving system that regularly pulls bursts of air back through its collection filters. The bursts knock loose accumulated dust and debris, keeping it from clogging the machine.
The machine’s three-filter system is electronically controlled. Two of the filters stay in vacuum mode as the third is cleaned, and the machine automatically cleans each filter in turn. Additionally, the vacuum’s “air dam” creates a cyclone effect that stops debris from recycling through the filters and directs it to the bottom of the tank.
Pulse-Bac’s vacuum system sets it apart from standard vacuums, which use blowers, shakers, compressors or magnets to flush filters clean.
There are two Pulse-Bac models, the HD for heavy-duty applications and the LD for lighter work. The HD generates 266 cubic feet per minute with 77 inches of lift, while the LD turns out 133 cfm with 77 inches of lift. Both machines include moisture-resistant filters that trap particles as small as 0.5 micron at an efficiency rating of 99 percent.
The vacuum can be attached to a wide range of concrete surfacing and cutting equipment. Concrete dust is Pulse-Bac’s bread and butter, notes McCutchen. “We sell primarily to the concrete surface preparation industry.”
The machine will also capture dust generated by stone, wood, fiberglass, drywall and other dry debris.
Pulse-Bac vacuums come with a 20-gallon powder-coated carbonate steel tank and a nylon grip handle for dumping. An optional extender for the HD model allows it to be placed on any standard 40-gallon or 55-gallon drum. As for noise, Pulse-Bac puts out less than 85 dB, which is at least as quiet as other vacuums, McCutchen says.
