For many contractors, a shop or industrial vacuum may be an afterthought. At the very least, you may not put a whole lot of time into choosing the vacuum that specifically fits your company's needs. After all, the expectations you probably have for your vacuum are pretty simple: It should pick up dust and debris, and it should last a reasonably long time without requiring a lot of fussing.
According to Bryon (Bru) Bruington, technical sales director at Kut-Rite Manufacturing Co., that mindset is a mistake. "Contractors should put as much thought into choosing and maintaining their vacuum as they do into their grinders or diamond-blade saws, " he says.
"A common misconception is that bigger is better. Contractors should consider their company profile (what type of work they typically perform), the ease with which the vacuum will accommodate their usual job, the efficiency of a vacuum, the maintenance required to keep the vacuum in top working order and, of course, cost. "
A large-diameter hose might suit the needs of a flooring contractor but be too cumbersome for the more detailed work of a countertop specialist, Bruington notes. "Or perhaps the type of work you typically do requires a vacuum that can handle a lot of rolling around. In that case you should pay attention to the strength and durability of the casters. "
Choosing a filter is also a consideration. Jobs that fall under EPA rules for either asbestos or lead paint abatement require that contractors be certified and use a high-efficiency particulate air (HEPA) filter. While HEPA filters are the cleanest available, they can be cost-prohibitive for contractors who are not required to use them. HEPA filters aside, most manufacturers offer a variety of filters for their vacuums.
HEPA or not, filters tend to get clogged by fine dust, reducing the efficiency of a vacuum. Many manufacturers offer a choice between manual and self-cleaning options. Most manual cleaning systems feature a type of push rod, allowing the operator to agitate the filter by pushing the rod, thereby knocking the dust off. Self-cleaners generally work in one of two ways - utilizing the vacuum exhaust system to agitate the filter or requiring attachment to a compressor.
"It's important to consider the man-hour ramifications when choosing between a self-cleaning and a manual-cleaning vacuum, " says Chris Hudson, president of Pathfinder Concepts LLC. "If your jobs generally require a lot of vacuuming, your crew may spend a lot of time manually agitating the filter. In that case a self-agitator probably makes sense. On the other hand, if a vacuum is only needed sporadically, the less expensive manual systems may be more appropriate. "
"Whatever features a contractor chooses, it's important to remember that concrete dust is abrasive. It's hard and aggressive on the innards of a vacuum, " says Bruington. "Today's vacuums are precise operating systems. They need to be maintained like any other high-end tool. A little maintenance can go a long way - clean the filter regularly, replace the filter when it wears out, and spend some time cleaning the mechanical parts. "

|HEPA certification and hazardous dust: Make sure your new vacuum fits the bill
Several pages into the Environmental Protection Agency's new Renovation, Repair and Painting
Rule, there is a statement pertaining to the use of HEPA certified vacuums: "HEPA vacuum means a vacuum cleaner which has been designed with a high-efficiency particulate air (HEPA) filter as the last filtration stage. A HEPA filter is a filter that is capable of capturing particles of 0.3 microns with 99.97 percent efficiency â€¦ "
Today, that's a starting point when you're looking for a vacuum, especially if the scope of work you perform includes renovations or demolition. In those cases, a HEPA certified vacuum may be required.
According to Chris Hudson, president of Pathfinder Concepts LLC, there are additional things contractors should consider when dealing with potentially hazardous dust: "A lot of people look at how efficient a vacuum is in picking up dust, but they don't think about how they're going to empty it when it's full. Concrete dust weighs about 12 pounds per gallon. A few gallons and you're dealing with some real weight. Additionally, if you're releasing hazardous dust when you empty the vacuum, the HEPA filter is really a moot point. "
Some manufacturers offer vacuums that feature a bottom port to which a plastic bag can be securely attached, creating a closed system into which the operator can empty hazardous material. Another option is the Longopac bagging system, which is a similar concept - a closed system utilizing securely attached plastic bags.
"Many manufacturers offer HEPA options with their vacuums, " says Bryon Bruington of Kut-Rite Manufacturing Co. "Just like with non-HEPA applications, contractors should consider the full scope of options when they're choosing a vacuum. "
