Roll-around shop vacs are handy devices that we’ve used for decades. Every shop has at least one that’s parked under a workbench. Plug it in, add an extension cord for dragging it to extended locations, suck up floor or bench debris, roll it over to the trash can, remove the top, empty the can, clean the filter, reassemble and store until needed again. Quality pro-built units work great, and cheaper units are readily available at any home improvement store. The downside: The really good ones are pricey, and the cheap ones are, well, cheap. Caster wheels tend to break off. They also tend to tip over when dragged around, and regardless of the price paid, they take up floor space during storage. The worst case scenario is the chance for motor burnout, requiring a total replacement.
Well, here’s a nifty alternative. Guardair offers a compact, hand-held pneumatic vacuum gun that simply hooks up to your shop’s compressed air. The gun is lightweight and easy to maneuver, and a host of extensions and tips are available for any situation. A compact collection bag attaches to the rear of the gun. Connect shop air, squeeze the trigger and vacuum up whatever junk is lying around. When you’re done, simply pop the bag off of the gun, zip it open and dump the contents.
Guardair’s 1500-series Gun Vac requires 29 scfm air usage and a minimum 7.5 hp air compressor. Incoming air line pressure needs to be set at 100 psi. This provides a vacuum lift of 75 in H2O, a vacuum flow of 78 scfm and a noise output of 89 dBA.
The Gun Vac is available in three versions: the basic 1500 kit that includes a high filtration collection bag and a 9-inch crevice tool, the 1510 deluxe kit that adds a five-piece plastic accessory group (a fiber bristle brush tip, upholstery/cloth tool with dual lint pads, multi-purpose swivel brush, 7-inch elongated brush and a 12-inch crevice tool) and the 1548 flexible kit that includes an 18-inch-long 1-5/16-inch OD flexible metal inlet extension.
An array of additional attachment options also are available, including a handy heavy-duty chrome-plated metal telescoping extension that expands from 24 inches to 40 inches. A mini-vacuum attachment kit is another handy option that allows easy and efficient vacuuming of small crevice areas such as ducts, instrument panel crevices, etc.
The gun features cast aluminum construction, with a machined tapered nose designed to accept any standard 1-1/4-inch vacuum accessory. The contoured trigger can be quickly latched in the open position via a trigger latch that’s built into the forward grip surface.
