Product Name: 94k Short Stop Filter Assembly (Part No. 391026-3)

Description:
This component is a high-pressure inline filter assembly, specifically designed for 94,000 PSI (approximately 6,480 bar) ultra-high pressure waterjet cutting systems . The Short Stop Filter is installed directly at the cutting head mounting collar, with the high-pressure water line connecting to it .

The assembly incorporates a fine mesh screen element that captures microscopic contaminants, debris, and particles from the high-pressure water supply before they can enter and damage the cutting head's orifice or IDE (Integrated Diamond Eductor) assembly . This filtration stage is critical as the final line of defense for protecting the ultra-precision diamond or sapphire orifice, high-pressure seals, and mixing tube from erosion, clogging, and premature failure.

The design is engineered for quick and safe servicing, allowing operators to clean or replace the mesh filter element without specialized tools . This component is specifically rated for 94k (94,000 PSI) systems and is fully compatible with 94k Advantage EP IDE cutting heads.

Applications:

• Installed at the cutting head mounting collar as the final filtration stage before the orifice

• Connects between the high-pressure water line and the cutting head assembly 

• Protects IDE (Integrated Diamond Eductor) cutting heads and standard orifice assemblies from debris damage

• Used in ultra-high pressure waterjet systems operating at 60,000–94,000 PSI

Features:

• Ultra-High Pressure Rating: Engineered for continuous operation at 94,000 PSI (6,480 bar)

• Fine Mesh Filtration: Captures microscopic contaminants before they reach the cutting head orifice 

• Critical Protection Device: Prevents debris-related orifice damage that causes poor cutting performance and premature replacement costs 

• Quick Service Design: Allows easy access for cleaning or replacing the mesh filter element without specialized tools 

• OEM Compatibility: Direct fit for 94k Advantage EP waterjet systems

Maintenance:

Mandatory Usage Requirement:

• An inline high-pressure filter such as the Short Stop Filter MUST be used with IDE (Integrated Diamond Eductor) cutting heads. Failure to use this filter will void warranties and damage the integrated diamond orifice.

Inspection Protocol:

• Visual Inspection: Periodically inspect the filter assembly for external water leakage or physical damage

• Mesh Screen Check: When servicing, examine the fine mesh screen for accumulated debris, tears, or damage

• Flow Monitoring: A significant drop in cutting performance may indicate a clogged filter element

Cleaning and Replacement Guidelines:

• Contaminant Removal: The mesh filter can be cleaned when minor debris is present. Use compressed air or low-pressure water to blow debris off the screen surface 

• Inspect for Damage: After cleaning, inspect the mesh for tears, holes, or distortion. Replace immediately if the screen is damaged

• Replace if Uncleanable: If debris cannot be effectively removed or the screen is clogged beyond cleaning, replace the filter element

• Service Schedule: Establish a preventive maintenance schedule for filter inspection based on operating hours and water quality

• Critical After Pump Rebuild: Always inspect and clean/replace the Short Stop Filter after any pump rebuild or major system maintenance, as debris from pump service can damage the orifice

Installation Notes:

• Install the filter assembly at the cutting head mounting collar with the high-pressure water line connected to it 

• Ensure proper orientation of flow direction as indicated on the filter body

• Tighten all connections to the torque values specified in the equipment service manual

• Apply high-pressure thread lubricant to connections during installation to prevent galling

Full Depressurization (Critical):

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