MPak^® Coalescing Plates

MPak^® Coalescing Plates are engineered for superior oil-water and solids separation across a wide range of demanding industrial and environmental applications. Manufactured by Facet, these innovative plates leverage a unique oleophilic (oil-attracting) material and bi-directional corrugation to optimize the aggregation and removal of oil droplets from water, while facilitating the settling of suspended solids for hassle-free cleanout.

With a modular, customizable design, MPak Coalescing Plates are ideal for both new installations and retrofitting existing oil-water separators, including challenging sites such as refineries, marine vessels, heavy manufacturing, and environmental remediation projects. Their adaptability ensures maximum system flexibility—supporting various plate spacings and configurations—so you can meet site-specific flow, footprint, and performance criteria.

Reduce downtime and maintenance with Facet’s patented MPak plates. The innovative design allows for in-place cleaning using the MPak Cleaning Wand, minimizing operational disruption and eliminating the need for filter consumables or frequent replacement parts. The result is a low-maintenance, high-efficiency separation solution designed for long life in aggressive industrial environments.

MPak Coalescing Plates are trusted worldwide for rainwater/stormwater treatment, refinery and industrial effluent control, washdown areas, offshore platforms, marine discharges, and much more.

Rely on MPak for consistent, reliable performance—helping you achieve regulatory compliance and protect your operation.
