Gilson Silent Sifters significantly reduce noise levels of sieving operations with no loss in performance and accuracy. Gilson’s innovative design and better materials reduce noise levels inherent to particle sizing more than other rotary sifters or sieve shakers. Faster conversion from 8 to 12in ASTM test sieves or 200mm and 300mm ISO test sieves, easier set up, and much quieter operation are all improvements over classic rotary sifters. Sieve stack capacity ranges from six 12in diameter full-height sieves with pan, or up to twenty 8in diameter half-height sieves with pan.
Enclosed cabinets allow safe, dust-free operation. Sieve stacks are simply placed inside and the cabinet is rotated back to the testing position using an ergonomic knob, no clamping is required. A drive roller system continuously rotates the sieve stack with particle separation assisted by tapping against the stack. The digital countdown timer with large LED display precisely times operation up to 99 minutes at ±1 second. Pause function allows the cycle to be suspended and resumed with no loss of test time, and a five-second audible alarm sounds at completion of the interval. The controller is simple to program and the large, bright 0.5in (126mm) LED display is easy to read.
Hammer assemblies are 6061 aluminum alloy with Ultra High Molecular Weight (UHMW) Polyethylene heads. Rugged painted case is dense, impact-resistant MDF board and is mounted on a sturdy, powder-coated ASTM A513 heavy steel tubing stand. The system is driven by a dependable 1/4hp continuous-duty motor.
The included floor stand with locking swivel casters allows for easy mobility.
The Gilson Silent Sifter II is the newest and most unobtrusive member of the Gilson Rotary Sifter line. This Sifter uses advanced, soundproofing materials and techniques for models 16 to 18dB quieter than standard rotary sifters and 8-10dB quieter than the original Silent Sifter. Heavy-duty, over-center lever latches pull doors tightly against case gaskets, ensuring a tight, dust-proof seal that enhances noise control. It operates at 115V/60Hz and has 4.7Amps.
Features:
- Lower operational noise levels than any other rotary sifter on the market
