Pleated Synthetic Filter Cartridges
HILCO PH Series
High-Efficiency Pleated Synthetic Filtration for Industrial Systems
HILCO Pleated Synthetic Filter Cartridges are designed to remove particulate contamination from hydraulic and lubrication systems using high-performance synthetic media. The pleated configuration increases filtration area, supporting consistent particle removal and stable operating performance in circulating fluid systems without being affected by water.
HILCO PH Series cartridges are used in applications where reliable fluid cleanliness is required to protect system components and maintain operational efficiency.

HILCO Pleated Synthetic Filter Cartridge Key Features:
Pleated Synthetic Microglass Media
Engineered synthetic media provides consistent particulate capture and stable filtration performance without being affected by water.
Increased Filtration Surface Area
Pleated construction expands usable media area to support improved dirt-holding capacity and service life.
Particulate Contaminant Removal
Removes solid contaminants from hydraulic and lubrication fluid systems to help protect critical components.
Stable Pressure Drop Performance
Designed to maintain consistent flow characteristics throughout service life under normal operating conditions.
HOW IT WORKS
Capturing Particles Within a Structured Synthetic Media Matrix
In circulating hydraulic and lubrication systems, fluid continuously carries wear particles generated by pumps, valves, and mechanical interfaces. This includes engine and turbine lube systems, where contamination can circulate through bearings, control valves, and other critical components. As these particles move through the system, they remain suspended in the fluid and repeatedly pass through sensitive components, increasing abrasive wear over time.

By capturing solid contaminants within a structured filtration path, HILCO PH Series Pleated Synthetic Filter Cartridges help deliver:
Surface Interception of Larger Particles
Contaminants are first captured at the outer layers of the pleated media where flow velocity begins to slow and distribute across the surface
Depth Loading Within Synthetic Fiber Layers
Smaller particles migrate into the media structure where they are retained across multiple internal layers rather than remaining in circulation
Flow Redistribution Across Pleated Channels
Fluid is guided through expanded pleat geometry, preventing localized loading and allowing more uniform use of the media surface are
Continuous Separation of Clean Fluid Pathways
Once particles are retained, clean fluid continues through the downstream side of the media without re-entraining captured contaminants
HILCO PH Series cartridges use engineered synthetic fiber media arranged in a pleated geometry to create multiple stages of particle capture. As fluid passes through the element, contamination is progressively removed through surface interception and internal depth retention within the media structure, allowing clean fluid to exit the element and return to the system. HILCO PH Series cartridges use pleated synthetic microglass media to provide high-efficiency particulate removal in hydraulic and lubrication systems.
