Rotary or Steam Jet?; (Continued from page 85) .FORESIGHT IS FAR-SIGHT C0 LLECTI 0 Blind buying is bad business. It's far better to know just how well new equipment is going to do its job-- before you buy. With Buell dust collection systems you can know--fully and exactly--how well your dust problem will be solved. Buell offers a unique,, pre-order, fractional efficiency guarantee. It's the only kind of efficiency that accurately pre dicts dust collector performance. What's more, the guarantee figures may pleasantly surprise you. for only the Buell system has the patented van Tongeren 'shave-off', a really important efficiency development. The complete facts are in a new 32 - page catalog--write to the Buell Engineering Company, 10 Cedar Street, New York 5, N. Y.
