Cyclone separators, also known as centrifugal separators, are used to separate fine, solid or liquid components from air flows. These devices are characterized by features such as a high separation efficiency, a sharp grade efficiency, a wide air volume capacity, and virtually maintenance-free operation.
Briefly summarized: Cyclone Separator
Cyclone separators use centrifugal forces to efficiently remove fine solid or liquid particles from air streams. They are known for their high efficiency, durability, and low maintenance requirements, making them ideal for use in industrial environments. Modern cyclone separators are highly versatile and can withstand high pressures and temperatures, allowing them to be used in a wide range of applications—from grain mills to blast furnaces.
What are cyclone separators and what are they used for?
Cyclone separators are a specialized type of inertial separator used to remove solid or liquid particles from gas streams. They utilize centrifugal forces, generated by creating a swirling flow, to effectively separate particles from the airstream. Unlike other types of inertial separators—such as gravity or inertia-based separators—cyclone separators achieve a higher level of separation efficiency. While gravity separators rely on particle sedimentation due to gravitational pull, and inertia-based separators remove particles through sudden directional changes in the flow, cyclone separators use centrifugal force to enable a more precise and thorough separation.
Advantages of cyclone separators
Cyclone separators are valued for their exceptional durability, making them a trusted solution in industrial environments for many years. They offer a simple and effective way of dust separation, and modern versions are capable of withstanding high pressures and temperatures, allowing for a wide range of applications—from grain milling to blast furnace operations. In addition to removing solid particles, cyclone separators are also suitable for extracting liquids from air, using the same operating principle.
High availability due to robust design
Because cyclone separators have a simple design and operate without moving mechanical parts, their maintenance requirements are minimal. This simplicity also results in low susceptibility to malfunctions, leading to high operational availability. Unlike filter systems, they do not require replaceable or cleanable filter media, reducing both downtime and maintenance costs.

Cyclone separators as part of filtration systems
Due to their construction, cyclones are incapable of completely removing finest dust from transport air. Finest particulate matter leaves the cyclone together with the exhaust air through the immersion tube, allowing it to re-enter the air stream. For applications requiring particularly thorough air purification, cyclone separators must therefore be combined with additional filtration technologies.
Cyclone separators from LTG
LTG cyclone separators are characterized by outstanding separation performance with low-pressure loss. Thanks to their innovative wear-resistant lining, they are especially durable and robust, even under extreme operating conditions. This design greatly reduces maintenance demands and minimizes downtime, making LTG cyclones a reliable solution for a wide range of industrial applications.
Another highlight of LTG cyclone separators is their versatility. The model ranges ZSA, ZSB, and ZSC cover air volumes from 100 to 5,500 m³/h, making them suitable for a broad spectrum of uses. Whether in woodworking, metallurgy, or food processing, their sturdy construction and effective particle separation ensure optimal air cleanliness across industries.

How does a cyclone separator work?
A cyclone separator consists of a conical housing into which a dust-loaden gas mixture is blown tangentially via an inlet cylinder. Air and particulate matter follow a circular downward spiral inside. As the diameter of the cone narrows, the velocity of the rotating airflow increases, which in turn amplifies the centrifugal force. This causes the dust particles to be flung outward against the wall of the cyclone, then pulls them down into a collection container at the bottom. The cleaned air spirals upward and exits through the immersion tube (air plenum) at the top.
Multi-Cyclone for high air volumes
When large volumes of exhaust air need to be cleaned, it is often more effective to use multiple smaller cyclone separators in parallel rather than a single large one. In such configurations, the system is referred to as a multi-cyclone. Depending on the application and airflow volume, a multi-cyclone can consist of numerous individual cyclones working simultaneously. This arrangement allows for the efficient cleaning of thousands of cubic meters of air per hour.
Where else are cyclone separators used?
In addition to their industrial applications, cyclone separators are also widely used in bagless vacuum cleaners, where they separate dust from air before it reaches the filter. They are also employed in the air filters of engines, especially in agricultural machinery and off-road vehicles that operate in particularly dusty environments. In these cases, the cyclone pre-separator significantly reduces the load on the main filter system, extending its service life and improving performance.
