QF puts the squeeze on costly conventional joining methods.
The QF clamp eliminates operations like riveting, cutting, braising and welding for standard length piping. These installation procedures are extremely time consuming and costly and, thanks to the QF, outdated. Most of these traditional techniques take a high-priced technician with special equipment several minutes per joint. A QF clamp goes on in a matter of seconds. Ductwork, including branch pieces and elbows, may be put together and taken apart with no special tools. And QF clamps are so easy to use, even your own employees can install them.

QF is not only quick, its strong.
This clamping system begins with pipes and fittings (i.e., 30°, 45°, 60°,  90° elbows) that have been specially machined by us so that their edges have double rolled lips. When the QF, with its built-in gasket is clamped over these two rolled edges and further secured with a cotter pin, the resulting seal insures the strongest, safest dust-extraction piping available.

QF works in new systems as well as existing ones.
QF will save you money whether you're planning to add, remove, replace or install dust-extraction piping. Any pipe that falls within a 4' to 22" diameter can be clamped together with QF, including slip joins and non-standard lengths. The pipe length can be adjusted a few inches or a few feet with our slip joints, and that reduces cutting and fabricating.

QF, No other company in America has it.
And that means no other company in America can give you a lower bid on filter systems. If you'd like to know just how much money you can save using QF clamps, we'll be glad to have a sales representative call you. You'll be extremely pleased with all the built-in advantages you get with QF. And with the quote we bring you. So call or write us today and find out why the QF is the best thing around.
