Considerations for Purchasing Output Force Frequency Air Consumption Noise Level Cost
TypesRotary Linear Higher frequency Lower frequency and lower force and higher force
Series BPVPneumatic Ball Vibrator Continuous vibration from air supply Low cost, low force, high noise, high air consumption
How It OperatesVibration is caused when theinternal ball, pushed by compressedair, runs in a rotary motion toproduce centrifugal force.
Series PRVPneumatic Roller Vibrator Continuous vibration from air supply High force, high noise, high air consumption
How It OperatesVibration is caused when theroller, pushed by compressed air,runs in a rotary motion toproduce centrifugal force.
Series PTVPneumatic Turbine Vibrator Continuous vibration from air supply High frequency, low noise, low air consumption
How It OperatesVibration is produced by centrifugal forcewhich arises from the imbalance ofmovement when compressed air impacts thetangent of the turbine to make it move.The operation noise is low because of ballbearing supports on the running turbine.
Series APVPiston Vibrator APV-C is air cushioned on both ends of stroke APV-I is only air cushioned on top stroke, direct impact on bottom stroke
How It OperatesThere are air-breathing tubes located inboth ends of the cylinder. Vibration isproduced when compressed air pushes thepiston from one side to the other.
Series APV-CAir Cushioned Piston VibratorAir cushions at both ends will keep the pistonfrom striking the body, hence minimizing thenoise produced.
Series APV-IImpact Version Piston VibratorAn air cushion at the top end will keep thepiston from striking the body top; however, thepiston will strike directly on the bottom of thebody producing a strong impact.
Series IPVAir Hammer One shot at a time Focuses on a limited target. Other areas of the target are minimally affected.
Series EBVElectric Bin Vibrator Continuous operation at 100% force output without overheating or mechanical damage Silent operation (20 dB) Adjustable centrifugal force increases application flexibility Power Requirements 120 VAC (60 Hz) 230 VAC (50 Hz)
