W.S. Tyler RO-TAP® RX-94
The RX-94 Test Sieve Shaker utilizes the same traditional design as the RO-TAP RX-29 and RX-30. This particular unit features a special cavity that allows for two “stacks” of 8 in. or 200 mm diameter test sieves.
As a result, twice the processing capacity is achieved in the same time required to complete one test with single-stack shakers is possible. The RX-94 model is designed for use with 8-inch. (200 mm) diameter test sieves only and features a newly designed easy-lock clamping system.
Each unit is tested and serialized before shipment. It features a 99-minute digital timer with a tolerance of .1 seconds.
- Designed for use with 8″ diameter Test Sieves only.
- Testing application: 2″ down through 635 mesh (20 micron).
- Newly designed easy lock clamping system.
