The NTK 18 AL is a linear pneumatic vibrator that is especially suitable for conveying, compacting and loosening bulk material. The unit uses a freely vibrating, self reversing piston to produce a sinusoidal oscillation and the vibrator starts and stops without delay in any installed position. The frequency may be continuously adjusted by regulation of the air supply and throttling the exhaust air adjusts the amplitude. There are a variety of mounting options such as attaching the housing or the piston to a vibrating mass and additional weights are available that can be used to alter the frequency and amplitude in many different ways. * Operating pressure 2 to 6 bar * Nominal frequency 1600 to 2350 min-1 * Centrifugal force range 41 to 109N * Linear vibration * Low noise levels * Aluminium housing * Drive medium compressed air or nitrogen, preferably with oil or mist Note: A directional control valve is required for operation (not supplied).
