Gilson 3in Vibratory Sieve Shaker

Gilson 3in Vibratory Sieve Shaker: Precision Sieving in a Compact Design

The Gilson 3in Vibratory Sieve Shaker stands out as a compact, quiet, and exceptionally efficient solution for the dry powder separation of small samples. Engineered for precision, this electromagnetic sieve shaker offers an effective size range from No.4 (4.75mm) down to No.635 (20µm) when utilizing woven-wire sieves, with potential for even finer separations depending on material characteristics. Its versatility makes it indispensable across numerous industries, including chemicals, minerals, pharmaceuticals, powdered metals, cosmetics, abrasives, ores, and food processing, consistently delivering accurate and reliable results.

Designed with operational flexibility in mind, its small footprint and inherent portability allow for convenient setup directly within process operations or for critical remote QC/QA applications. The Gilson 3in Sieve Shaker boasts a high-frequency electromagnetic vibratory action, operating at 3,600 VPM (vibrations per minute) at 60Hz or 3,000 VPM at 50Hz (for 120V models). This powerful vibration is paired with a precise 0–100% amplitude control, enabling operators to fine-tune settings for optimal separation of even the most challenging fine powders.

A key differentiator is the integrated in-line solenoid-actuated tapping action. This mechanism delivers 60 taps per minute during the sieving cycle, strategically redistributing the sample on the sieve surface and actively breaking up static blinding. This ensures that undersized particles rapidly clear the mesh openings, significantly enhancing efficiency and accuracy.

User convenience is prioritized with the unique Gilson EZ-Clamp system. This innovative design simplifies the insertion and removal of sieve stacks. Ergonomic knobs allow for a quick twist to release or secure the stack, while the clamping mechanism maintains a fixed height until tightened, eliminating the need for constant re-adjustment.

The shaker accommodates standard 3in (76mm) diameter test sieves, whether they are stainless steel or clear acrylic frame sieves. Each unit includes the SSA-17 3in Acrylic Sieve Adapter and a metal sieve cover. For enhanced visibility and diagnostic capabilities during operation, optional accessories like the SSA-15 or GAA-88 Acrylic Spacers can be ordered, allowing observation of sample action while leveling the platform or setting vibration.

Constructed with a rugged, powder-coated steel case, the Gilson 3in Sieve Shaker is built for durability. It features a variable control for vibration intensity and offers both manual and timed operational modes. The integrated digital countdown timer provides precise control, with a capacity of up to 99 minutes and 59 seconds, accurate to ±1 second. Its clear 0.5in (12.7mm) LED display ensures readability, and a pause function allows for temporary suspension and resumption of cycles without loss of test time. A five-second audible alarm signals the completion of testing, ensuring no process goes unnoticed.

The Gilson 3in Sieve Shaker operates on a 115V, 50/60Hz electrical supply. For international compatibility or operation on 230V systems, the TR-502 Step-Up/Step-Down Transformer is available as an essential accessory.
