Endecotts a range of Sieve Shakers. The Octagon is ideal for laboratory or on site use. It is robust, compact and sufficiently lightweight to be portable. A digital display makes the setting of the microprocessor controlled functions very straightforward. The Octagon is powered by an electromagnetic drive which has no rotating parts to wear making it maintenance free and extreemly quiet in operation. The vibratory action produced by the power unit moves the sample over the sieve in a inique way producing faster more efficient sieving, while the rapid vertical movements also help to keep the apertues from blinding. The Octagon's digital controller is used to set both the process time and the amplitude setting while a further control enables the vibration to run continuously or intermittently. Intermittent vibration improves performance and helps to clear apertures that may have become blocked.
