This new HEPA vacuum is designed specifically to be used with power
tools and dust management in construction and restoration job sites. The
model 45HEPA-TT has a "Tool Trigger" feature allowing the operator to
turn the vacuum on or off through the power tool. Stricter worker and
environmental regulations are requiring tradesman who cut and grind
concrete and masonry materials to control dust. Collecting and
containing dust increases worker and power tool productivity, extends
life of the abrasives and reduces clean-up time and expense.
