DOV-AL Series Pneumatic Linear Vibrators with External Piston are similar to the Standard DOV design but have anodised aluminum housings which can be operated on greatly reduced lubrication and in some cases can be lubrication free. Linear vibrating force is delivered by a noiseless air cushioned piston. Frequency and amplitude can be regulated independently. Using additional masses the vibrator is able to work at low frequencies and to generate large amplitudes. DOV-AL linear oscillating vibrators combine the advantages of low frequency rotary vibrators (large amplitudes) with those of magnetic vibrators (adjustable amplitudes). Additionally, they have the advantage of being able to select the most suitable frequency to obtain optimum results.
