Precision-machined MDF board cabinet seals tightly to control bot noise and dust levels for safe, clean and quiet operation. Settings are saved between cycles for precise repeatability and easy, one-button operation. The 99-minute digital countdown timer with large LED display precisely times operation, and pause function and user-selectable modes offer greater versatility. Sieves are rotated while active tapping assists particle separation. The sieve stacks are simply placed inside, and the cabinet is tilted back, no clamping is required. The Silent Sifter ll® is 16 to 18dB quieter than standard rotary sifters, and 8 to 10dB quieter than even our own Silent Sifter®.Ĩin, 12in, 200mm or 300mm diameter test sieves can be used in this model with sieve stack capacity up to six 12in diameter full-height sieves with pan, or twenty 8in diameter half-height sieves with pan. This proven sieving method preferred by many DOT’s is made safer and more reliable using specially engineered and advanced soundproofing design. A heavy duty, over-center level latch pulls the door tightly against the case gasket. Also, 8 to 10dB quieter than the SS-21 Silent Sifter. The sifter is 16 tp and 18dB quieter than standard rotary sifters. Gilson Rotary and Silent Sifters with Tapping (SS-20, SS-21, SS-22)When your high production testing lab needs to perform accurate sieve analysis on a broad. This adjusts the springs controlling the tapping hammers for the best tapping force. The Gilson Silent Sifter II come engineered with advanced soundproofing materials and techniques. This model sets a new standard for controlling harmful noise output in the laboratory while delivering accurate particle separations. Gilson Silent Sifters ®: SS-21 & SS-22 the sieve size selector knob on the front control panel to 12 or 8. Silent Sifters can instantly convert between 8in, 12in, 200mm, or 300mm test sieve diameter size. Gilson’s Silent Sifter® ll is another proven Rotary Sifter from Gilson for accurate and efficient sieving tests.
Lowest Noise Levels of any Rotary Sifter.Uses rotating and tapping for accurate, repeatable sieving of dry granular materials and powders
