Multi-Aspirator®for particle density separation

We separate material better than anyone, which is what separates us from everyone. The Kice Multi-Aspirator® efficiently and accurately removes dust, debris and other unwanted fines from products with higher densities. In the Multi-Aspirator®, the product stream is exposed to air up to six times. Each pass forces further separation of fines from the product. The Multi-Aspirator® achieves a standard of separation that our competitors cannot match.

The higher the capacity, the wider the Multi-Aspirator®. As the width increases, space sometimes requires the use of double Multi-Aspirator® systems. This arrangement uses two units placed back-to-back with a common air outlet fitting.


The Multi-Aspirator® is designed for industries that depend on dry separation systems, so applications are virtually endless. Examples include the processing of food, grain, cereals, seeds, hemp, plastics and wood.

At the request of customers, Kice performs tests on hundreds on different products every year. Our lab is able to simulate an actual Multi-Aspirator® system and accurately predict the viability of each product. Through testing, we can determine the proper loading and the proper air volume required for each product. If you have a product that could possibly benefit from the use of the Kice Multi-Aspirator®, request a lab test today.


E-Series Multi-Aspirator®

systems use the standard slide angle that has been engineered and proven most efficient for over fifty years. The E Series is the most commonly used model.

F-Series Multi-Aspirator®

systems use the same standard slide angle but have a shorter overall height than the E Series. The F Series can be used on products that have higher bulk densities and flow well.

Custom-designed Multi-Aspirator® systems typically have steeper slide angles. They are available for products with very low bulk densities that do not flow well. We design custom Multi-Aspirator® systems based on our lab tests.

Standard features

  • 4-pass and 6-pass units come standard. 2-pass and 3-pass units are available when headroom is a major concern.
  • Removable front slides allow access into the entire interior of the unit.
  • Support feet secure the unit to a floor or support structure.
  • Stock inlets are flush with the top of the unit and have threaded holes for bolting inlet transitions on to the unit.
  • Bolt-on access doors on the end of each unit allow for access to the inside of the units for blow down cleaning.
  • Lexan® doors with quick release clamps on the ends of the units allow visual inspection of the process.

Construction materials include mild steel painted Kice white, 304 stainless steel, polished 304 stainless steel with smooth and polished welds, as well as many other materials for unique applications.

Custom features

  • Different air outlet styles are available to fit virtually any field requirements.
  • Turning vanes in the air outlet fittings ensure even air flow across the Multi-Aspirator®.
  • Air inlet filters provide clean air to the Multi-Aspirator®. These are commonly used in the plastics and pharmaceutical industries.
  • Anti-static packages reduce the influence of static electricity on certain products. These are commonly used in the plastics industry.
  • Drop front slides provide easy access to the interior for cleaning.
  • Inspection ports below the bottom slide allow the operator to retrieve samples and monitor performance.
  • Plexiglass windows on the air outlet manifold allow for visual inspection during operation.
  • Return air plenums allow for a closed-loop system. Typically, fines are removed by a cyclone, and the air is returned to the Multi-Aspirator®. This negates the need for a baghouse filter but is not recommend for maximum performance.
  • Hinged front units provide quick and easy access to the interior of the unit. These are commonly used on products that require regular cleaning of the machine.
  • AR steel or ceramic-lined slides increase the life of a unit that handles abrasive materials.
  • A dockage tester is a small tabletop unit that is used for testing samples of products. The unit is prewired and operated from a common 110V wall outlet. The unit weighs less than 150 lb with a footprint of 9′ 2″.

Optional tabletop units


This tabletop unit can be fed from a screw conveyor, overhead surge bin or by hand. Ideal for small cleaning jobs or batch type operations. The suction fan is located in the top of the receiving cyclone. A cyclone discharges liftings into an airtight container below the support table.


Similar to the 6DT8-2, the 6DT8-3 comes with a cyclone and airlock added to the stock inlet of the Multi-Aspirator®. This arrangement allows for the system to be fed by a small pneumatic conveying line.


A cyclone with an internal suction fan is mounted on the stock inlet of the Multi-Aspirator®. This allows product to be conveyed by negative pressure to the system from a gaylord or other open container sitting next to the system.


Similar to the 6DT8-4, the 6DT8-5 includes an additional airlock below the receiving cyclone/fan. This allows for an open top container below.
