Wet Screening or De-Sliming Equipment

MARC manufactures and supplies a wide range of equipment to assist with particle sizing tasks. This range extends from simple singe-sieve pneumatic vibrator straps to full sieve shakers.

***For sieve shakers that can be used for wet sizing using stacks or towers of multiple sieves please browse the Haver & Boecker page on our website by clicking here.

  • This unit is designed to sit over a sink.
  • The vibration amplitude is adjustable.
  • *This range has been expanded to include a heavier duty drive system with the ability to clamp two sieves on top of each other – see table below for options*

Low Cost Pneumatic Single Sieve Vibrator Strap




  • A stainless steel vibrating strap that wraps around a standard 200, 300 or 450mm sieve that operates with compressed air only.
  • Safe for use in wet areas. Uses a “silent” pneumatic vibrator.
  • These are designed to be cost effective enough for multiple units to be used simultaneously.

Test Sieve Grade ISO 3310-1 Woven Wire Mesh Sweco or Kason Separator Replacement Decks


  • Most decks used on this class of equipment use industrial wire screen grade mesh (ISO 4783-1) and not test sieve grade (ISO 3310-1). This means that laboratory sizing results derived from a Sweco or Kason (or other) would not pass a quality audit. 
  • Sweco or Kason Vibratory Screeners can, however, be fitted with Test Sieve Grade Mesh to convert these to useful shakers for larger samples.
  • Because of the various makes and models of vibratory screeners available please contact us for details on this service.
