Process Filter Cartridge
HILCO 330 Series
Process Filtration for Improved Fluid Cleanliness
HILCO Process Cartridges are designed as a direct replacement for conventional string-wound filter elements used in industrial fluid systems. Available in both standard and extended tube configurations, these process filter cartridges provide effective particulate removal while helping improve overall system cleanliness levels.
HILCO 330 Series Cartridges are offered in disposable and washable designs, providing flexibility for a wide range of process filtration applications.

HILCO Process Cartridge Key Features:
Direct Replacement for 330 Series Elements
Designed as a drop-in replacement for standard 330 and 330 extended tube cartridge configurations.
Alternative to String-Wound Filters
Provides an upgraded filtration option for systems traditionally utilizing string-wound elements.
Disposable and Washable Configurations
Available in multiple cartridge constructions to support varying maintenance and operating requirements.
Metal or Nylon End Cap Options
Offered with multiple end-cap materials to accommodate different process conditions and system requirements.
HOW IT WORKS
Removing Particulate Contamination from Process Streams
Many traditional process filtration systems rely on string-wound elements, where fluid follows a relatively limited filtration path through layers of wound material. As contaminants accumulate, available filtration area can become concentrated in specific portions of the element, reducing effective media utilization.

By increasing available filtration area, HILCO 330 Series Process Cartridges help deliver:
Greater Contaminant Loading Capacity
Distributes captured particles across a larger media surface
More Efficient Media Utilization
Allows the filtration media to participate more uniformly throughout the service cycle
Improved Fluid Cleanliness
Continuously removes suspended particulate contamination from the process stream
Flexible Maintenance Strategies
Available in washable and disposable configurations to support varying operating requirements
HILCO 330 Series cartridges utilize a pleated filtration structure that creates a controlled flow path through the media. As fluid passes through the element, particulate contaminants are captured within the filtration media while clean fluid continues downstream. The increased filtration area helps distribute contaminant loading across the cartridge, supporting effective industrial process filtration throughout the service interval.
Industries
