In the past, users have been forced to decide between powerful force or quiet operation.  Impacting models are effective, but loud.  Non-impacting models are more polite, but not so forceful. At Houston Vibrator, we thought you should have a third choice – quiet and powerful.  The patented design of QI (Quiet Impact) Series Pneumatic Piston Vibrators provides the powerful linear force needed to solve your toughest bulk material flow problems, but reduces noise by up to 20%.  Like an impacting model, the piston actually strikes the bottom of the vibrator body, but with a rubber tip, it makes a lot less noise doing it.  The QI Series includes five models to handle a wide variety of applications.  

 

Standard features & benefits:
• Oil-resistant rubber tip reduces noise without major force reduction
• CNC Machined bodies & pistons ensure reliable operation
• Force & frequency are adjustable by varying supply air pressure
• Efficient operation - uses less air than rotary vibrators with comparable force
• Low maintenance when installed with proper air-prep components
