Chevron & Mesh Mist Eliminators
Mist eliminators are designed to remove moisture in industrial processes where liquids and gases come in contact. Several types are available, with different designs suitable for various applications:
- Chevron mist eliminators, also known as vane-type or baffle-type mist eliminators, are among the most common and offer reliable performance in high liquid load and high capacity processes.
- Mesh-type mist eliminators, including wire mesh mist eliminators, consist of several layers of wire mesh screening held together by a pair of support grids.

Features and Characteristics
Which Type of Mesh Eliminator is Right for You?
Wire mesh-type products are one of the most common choices, in part because of their economy and efficiency. The allowance to fine-tune their performance using different mesh geometries makes them extremely versatile.
Chevron mist eliminators offer excellent performance at an affordable price point. Their design makes them suitable for use in high-velocity and high-capacity applications, as well as in processes where a wire-mesh type product would clog easily. They offer good turndown characteristics and the lowest pressure drop of any mist eliminator design. Their versatility — and the range of materials and configurations MACH Engineering offers — makes them a smart choice for many applications.
Vane Type Mist Eliminator Features
MACH chevron mist eliminators consist of rows of parallel plates, or vanes, arranged in a zigzag formation. As a gas passes through the plates, mist impinges and coalesces on the vane surface, then drains downward, efficiently removing liquid from the stream. Vane-type mist extractors can be used for vertical and horizontal gas flows.
Mesh Mist Eliminator Features
Mist eliminators install directly into a vessel or process tower. As vapor passes through the mesh, liquid droplets will adhere to the surface, coalesce and runoff. The process itself is simple, though the choice of material, opening size, and other design considerations will all affect performance.
We typically produce mesh components from either metal or polymer. Polypropylene (PP) is the most commonly used — and cost-effective — option. It offers good resistance against acidic and alkaline chemicals. Stainless steel, on the other hand, is more expensive, though better suited to extremely high temperatures, easier to clean and more durable.
While the materials above are the most common, our mesh mist eliminators are also available in the following materials and are suitable in the following applications:
- PP (polypropylene)
- Distillation towers
- Steam drums
- Wet scrubbers
- Knockout drums
- Crude oil refinery vacuum towers
- Utility flue gas desulfurization (FGD) systems
- Phosphoric and sulfuric acid plants
- Pulp and paper mills, sugar refineries, chemical plants
- Upstream and downstream refineries and gas processing facilities
- Pickling lines, steel mills and foundries
- And other equipment
Choosing a product that’s appropriate for the application delivers several benefits, including:
- Minimizing the risk of contamination that can affect downstream chemicals
- Reducing the amount of wear incurred by turbine blades and other costly system components
- Increasing throughput and capacity, enabling better productivity system-wide
- Reducing pollution and making it easier to meet environmental and regulatory benchmarks
- Delivering a purer finished product
Together, these benefits translate to an improved bottom line. See how quickly your purchase will deliver a return on your initial investment by having a MACH Engineering representative perform the calculations for you.
