Gas Coalescer / Separator Filter Cartridges
HILCO GC Series
Gas-Liquid Coalescing Separation for Industrial Gas and Lubrication Systems
At the core of every HILCO Gas Coalescer / Separator Filter Cartridge is a precision-engineered gas coalescer cartridge designed to remove entrained liquids from gas and vapor streams. Using controlled coalescence, fine droplets are captured and combined into larger particles for efficient separation and removal within the system.
HILCO GC Series cartridges are used in industrial gas processing and rotating equipment lubrication systems where reliable liquid removal is required to maintain system performance and protect downstream components.

HILCO Gas Coalescer / Separator Filter Cartridge Key Features:
High-Efficiency Coalescing Media
Engineered media designed to capture and combine fine liquid droplets suspended in gas streams.
Gas-Liquid Separation Performance
Removes entrained moisture and hydrocarbon liquids from industrial gas and lubrication-related systems.
Staged Separation Efficiency
Promotes droplet growth through coalescence for effective gravity-based separation.
Drop-In System Compatibility
Designed for integration into HILCO gas separation and coalescing system configurations.
HOW IT WORKS
Removing Entrained Liquids from Gas Streams Through Coalescence
In industrial gas and lubrication systems, entrained liquids such as moisture or hydrocarbons can become suspended in gas streams during compression, circulation, or process operation. If not removed, these liquids can reduce system efficiency, increase wear, and negatively impact downstream equipment performance.

By capturing and coalescing entrained liquid droplets, HILCO Gas Coalescer / Separator Cartridges help deliver:
Improved Gas Quality
Reduces liquid contamination in gas streams
Enhanced Equipment Protection
Minimizes wear and damage in downstream components
Improved System Reliability
Supports stable operation of rotating equipment
Reduced Maintenance Requirements
Helps limit contamination-related service events
Industries
Proven Across Industrial Gas and Rotating Equipment Applications
HILCO GC Series gas coalescer/separator cartridges are used in applications where entrained liquid removal from gas streams is critical to maintaining equipment performance and system reliability.
WHY HILLIARD
Why Companies Choose HILCO Gas Coalescer/Separator Cartridges
Liquid Aerosol Removal
Coalescing media captures fine liquid aerosols entrained in gas streams and combines them into larger droplets for downstream separation.
Coalescing and Separation in One System
GC cartridges work within coalescer/separator equipment to remove entrained liquids while allowing the conditioned gas stream to continue through the system.
Protection for Downstream Equipment
Removing liquid contamination before it reaches compressors, turbines, instrumentation, and other downstream components helps maintain the required gas quality for critical equipment.
Engineered for Industrial Gas Conditioning
HILCO combines coalescing cartridge technology with filtration equipment and application expertise to address gas-stream contamination requirements across industrial systems.
