Product Name: Filter Cartridge, 10″, 222/Flat Cap Style (Part No. 400023-1-1S)

Description:
This component is a 10-inch water filter cartridge featuring a 222/Flat Cap Style end cap design, specifically engineered for the low-pressure water filtration system of waterjet cutting equipment . The cartridge is manufactured with a durable plastic core that provides structural strength and longevity under continuous water flow conditions.

The male end of the cartridge is secured by two red O-rings, which create a reliable, leak-free seal within the filter housing. The opposite end features a flat plastic cap with a raised inner shoulder, designed to properly align and center the cartridge inside the low-pressure water filter assembly . The cartridge serves as a consumable filtration component, removing particulate contaminants, sediment, and debris from the water supply before it enters the intensifier pump and high-pressure water circuit.

Applications:

• Primary or secondary sediment filtration in the low-pressure water supply line of waterjet cutting systems

• Installed in a compatible filter housing upstream of the intensifier pump

• Removes suspended solids such as fine sand, rust particles, silt, and other insoluble sediments from the water supply 

• Protects critical high-pressure components including check valves, dynamic seals, the ceramic plunger, and the jewel orifice (sapphire/diamond nozzle) from abrasive wear and clogging

• Compatible with H2O Jet waterjet systems (replaces OEM # 400023-1-1S) and cross-references with WSI # FW400023-1-1S and A-14-0100 

Features:

• 222/Flat Cap Style: Industry-standard end cap configuration for secure fitment in waterjet filter housings 

• Double O-Ring Sealing: Two red O-rings on the male end provide reliable, leak-free sealing within the filter housing 

• Durable Plastic Core: Provides structural strength and prevents collapse under flow pressure 

• Alignment Feature: Raised inner shoulder on the flat cap ensures proper centering of the element inside the filter assembly 

• Lightweight: Product weight is approximately 0.384 lbs (0.174 kg) for easy handling during maintenance 

• Disposable Component: Designed as a single-use consumable for periodic replacement

• Standard 10-Inch Length: Compatible with industry-standard low-pressure filter housings

Maintenance:

When to Replace (Failure Diagnosis):

• Filter Gauge Indication: Replace when the filter gauge reads 25 psi or lower while the pump is running, indicating significant clogging

• Scheduled Preventive Maintenance: Replace the cartridge on a regular schedule based on operating hours and water quality (typically every 500-1,000 operating hours or 3-6 months)

• Pressure Drop Monitoring: A significant reduction in water flow or increase in pressure differential across the filter indicates a clogged element

• Premature Component Wear: Frequent replacement of jewel orifices, high-pressure seals, or check valves may indicate the filter is not being replaced often enough

• Visual Inspection: If the cartridge appears discolored (brown/black), coated with sediment, or physically deformed during a housing check

Replacement Guidelines:

• Full Depressurization (Critical): Before any maintenance, fully depressurize the waterjet system (high-pressure water, hydraulic system, and air supply), shut off the water supply, and follow lockout/tagout procedures

• Disposable Component Only: This is a single-use filter cartridge. Do not attempt to clean or reuse it, as this will damage the filtration media and may allow contaminants to bypass

• O-Ring Inspection: Inspect the two red O-rings on the new cartridge for any damage before installation. Lubricate them with a small amount of clean water or manufacturer-recommended lubricant to ensure proper sealing and prevent damage during insertion 

• Housing Inspection: Before installing a new cartridge, clean the inside of the filter housing thoroughly. Inspect the housing sealing surfaces for damage or debris

• Proper Seating: Ensure the cartridge is correctly seated on the housing's internal standpipe or alignment guide. The raised inner shoulder on the flat cap should align properly to prevent water bypass 

• Housing O-Ring Maintenance: Inspect the filter housing's main O-ring or gasket (if separate from the cartridge) every two years and replace it immediately if leaking is detected

• Torque Compliance: After installing the cartridge, close and tighten the filter housing cap to the torque value specified in the equipment service manual

• Record Keeping: Keep maintenance logs recording filter change dates and operating hours to establish an optimal replacement schedule for your specific water quality

• Storage: Store spare filter cartridges in a cool, dry environment, preferably in sealed packaging, to prevent contamination or moisture absorption before use
