QI Series Piston Vibrators
Available from Houston Vibrator, Ltd.
The design of the QI Vibrator provides about 25% less noise than traditional impacting vibrators, while still delivering 90-95% of the force of the same size impacting model. Sizes range from 1-1/2" to 3-1/2" piston diameters. The QI Series is very useful in indoor or enclosed locations where noise reduction is a key issue.
