Quality Vacuum Products Nu-Matic system delivers vacuum pressure for veneering, laminating, and clamping—all the things you might want a vacuum pump for. Unlike an electric pump, this one is powered by compressed air; rather than plugging the unit in, you use it in tandem with your compressor.

I tested the “Pro” level system, which requires an air compressor capable of 4 cfm, but smaller and larger units are available. I went with the All-In-One (FS) system, which includes a foot pedal, letting you work hands-free on clamping jobs. The system includes all of the connections you need to attach it to any vacuum bag (QVP offers a wide range of those), and all gauges and controls are built into the box. 

What’s great about a unit like this is that it can be switched from pressing mode (with a vacuum bag) to clamping mode. In pressing mode, the unit automatically shuts off when the desired vacuum is reached and resumes when the level drops. But when the unit is switched into pneumatic clamping mode, commercial or shopmade vacuum blocks can hold workpieces firmly and instantly for routing and other tasks. In clamping mode, the unit maintains continuous high pressure, turned on and off with a handy foot switch. Various packages are listed at QualityVak.com, and you can call 800‑547‑5484 for more info.
