Cyclone Separators

REES manufactures centrifugal cyclone separators to collect medium to coarse dust particles in a variety of applications ranging from small shops to large plants. We also custom fabricate cyclones to customer specifications in carbon steel, galvanized steel, and stainless steel.

Abrasion inlet plates and liners can be added for tougher applications. As stand-alone collectors or as primary separators in front of filters, cyclones are a low-maintenance and cost-effective solution for many dust collection applications.

The proper type of cyclone separator for your plant depends on the specific type of job you need your cyclonic separator to perform. The centrifugal nature of cyclone separators means that no one separator is suitable for every job; consider the average size of the particles you’ll be filtering out, the velocity of the air moving through the separator, your desired level of efficiency vs. performance, among other factors.

REES also offers optional add-ons to cyclonic separators that make it better suited to the precise conditions of your plant and/or your processing needs. Consider add-ons like our Rain Elbows and Reverse Cone Rain Caps for protection from the precipitation and other elements, Closed Loop Caps and Backdraft Dampers for a cleaner airway with little human intervention.

Cyclone separators make up an integral part of many firms’ dust collection solutions, not only for their cost-effectiveness but for their versatility. Of the three standard REES cyclone separators, there is a cyclone and add-on combination to suit most dust collection and separation needs. Read on below to read more about each individual REES cyclonic separator, and the matching accessories.

Standard REES Cyclones

Model K

The REES Model K cyclone is used in applications where larger particles exist like chips or shavings. Also the Model K is used where height restrictions pose a problem.

Cyclone K

Model RHV

The REES Model RHV cyclone is used in applications involving higher velocities, finer dust particles, or more abrasive materials. The RHV has bolted sections with a tangential scroll inlet and a horizontal outlet.

Cyclone RHV

Model KL

The REES Model KL cyclone is similar to the Model K but with a longer cone section.  It is used where more efficiency is needed for mixtures of finer particles.

Cyclone Separators Options

Rain Elbow

Bolts to top of cyclone providing the most efficient way to vent air to the atmosphere.


Reverse Cone Rain Cap

Offers most economical solution for covering air outlet.

Reverse Cone Rain Cap

Cleanout Door

Provides access to lower cone section for inspection and maintenance.


Closed Loop Cap

Enables air discharge to connect to a closed-loop relay system or draw-through clean air fan.

Closed Cap Loop

Multiple Inlets with Backdraft Dampers

For multiple system entry and protection from dust-laden air returning back to the plant through the ductwork.


Many businesses also invest in closeout doors for easy access to the filtered material. For plants that need quantifiable data on their filtered material quickly or frequently, a closeout door is a must. This also makes determining the need for and performing maintenance easier, as the cyclone separator’s interior and operation chamber are very easily accessed in comparison to those without a closeout door.

In conclusion, cyclone separators stand as a critical component in the dust collection systems of many businesses, owing to their efficiency, cost-effectiveness, and adaptability. The inclusion of closeout doors in these separators enhances their functionality by facilitating easy access to the filtered material, thus simplifying maintenance and allowing for prompt evaluation of the collected material. With the availability of different models and customizable options, such as the three standard REES cyclone separators, organizations can select a combination that best fits their specific dust collection and separation requirements. The versatility and effectiveness of these systems make them an invaluable asset in maintaining a clean and efficient operational environment. Contact us today!
