Pleated Cellulose Filter Cartridges
HILCO PL Series
Pleated Cellulose Filtration for Industrial Fluid Systems
HILCO Pleated Cellulose Filter Cartridges are designed to remove particulate contamination from hydraulic, lubrication, and general industrial fluid systems using an organic cellulose media. The rounded pleat construction increases surface area while the cellulose fiber structure provides reliable dirt-holding capacity and stable filtration performance.
HILCO PL Series cartridges are used in applications where consistent particulate removal is required to support equipment protection and maintain fluid cleanliness.

HILCO Pleated Cellulose Cartridge Key Features:
Pleated High-Surface Area Design
Increases effective filtration area to improve dirt-holding capacity and extend service life.
Particulate Contaminant Removal
Removes solid contaminants from hydraulic, lubrication, and industrial fluid systems.
Stable Filtration Performance
Provides consistent particulate removal in general-purpose industrial applications.
Broad Fluid Compatibility
Suitable for a wide range of petroleum-based and industrial fluids.
HOW IT WORKS
Removing Particulate Contamination from Industrial Fluids
In industrial fluid systems, contamination is introduced through component wear, system ingress, maintenance activities, and fluid degradation. These particles circulate through pumps, valves, and mechanical components, where they can accelerate wear and reduce system efficiency if not removed.

By removing solid contaminants from fluid streams, HILCO PL Series Pleated Cellulose Cartridges help deliver:
Improved Component Life
Reduces wear on pumps, valves, and mechanical systems
Improved System Reliability
Supports consistent fluid performance
Enhanced Fluid Cleanliness
Helps maintain acceptable contamination levels
Reduced Maintenance Costs
Minimizes wear-related repairs and downtime
HILCO PL Series cartridges use pleated cellulose media to capture particulate contamination as fluid passes through the element. The cellulose fiber structure provides depth-based filtration, trapping particles throughout the media while allowing fluid to continue through the system. The pleated design increases surface area, improving dirt-holding capacity and extending service intervals. This cellulose filter cartridge is used for particulate control in general industrial fluid systems.
Industries
General Purpose Filtration Across Industrial Markets
HILCO Pleated Cellulose Cartridges are used in industrial environments where particulate removal is required to maintain fluid cleanliness and support equipment performance. The PL Series can be applied as a lube oil filter cartridge in circulating lubrication systems and as a hydraulic oil filter cartridge in hydraulic fluid systems.
