Bosch has introduced a new lineup of 9- and 14-gallon vacuums. The VAC090S and VAC090A 9-gallon vacuums and VAC140S and VAC140A 14-gallon vacuums are designed to increase dust extraction performance and decrease the loss of suction by offering two options of on-board filter cleaning; semi-automatic and automatic. These features are especially important in applications that require premium dust extraction such as tuckpointing, concrete surfacing, concrete drilling, cutting and chipping concrete, and collecting a diversity of dust particles in stationary workshops.
The SVG3 Digital Micron Vacuum Gauge includes a large dual display with rate indicator, alarms, timers, a rubberized case, and rugged strap and hook that hangs at an angle to make reading the display easy. The dual display indicates live vacuum measurement in microns of mercury on the top line, and the rate of micron change, or the alarm stopwatch on the bottom line.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop.
