938993Q High-Efficiency Coreless Hydraulic Filter Replacement

📊 Technical Specifications

🛠 Professional Product Description

How the 938993Q Hydraulic Filter Protects Your System

A hydraulic filter is a critical component designed to remove microscopic particulates-such as silica, metal shavings, and silt-from pressurized oil circuits. The 938993Q utilizes high-density glass fiber media to intercept contaminants that cause "sandblasting" wear on sensitive servo valves and high-pressure pumps. By maintaining an ISO 4406 cleanliness code of 18/16/13 or better, this filter prevents unplanned downtime and extends the Mean Time Between Failures (MTBF) of the entire hydraulic power unit.

Why Choose Our Glass Fiber Replacement?

Most standard filters fail due to "media migration" or pore clogging under cold-start conditions. Our 938993Q replacement solves these pain points through:

• Stable Beta Ratios: Unlike cellulose, our synthetic glass fiber does not swell or degrade when exposed to moisture or chemical additives.
• Pressure Drop Optimization: The pleated geometry is calculated to minimize initial differential pressure, reducing energy consumption in the hydraulic system.
• Viton Sealing Superiority: While competitors use standard Buna-N, our inclusion of Viton seals ensures compatibility with aggressive synthetic fluids and high-heat industrial environments.

Performance Comparison: OEM vs. Our Premium Replacement

Our manufacturing process focuses on Performance-Parity. While OEM brands often carry a 40-60% price premium due to marketing overhead, our 938993Q maintains the exact same micron rating ($\beta$ value) and dirt-holding capacity (DHC). We utilize ISO 16889 multi-pass testing to verify that our elements meet or exceed the original Parker specifications.

❓ FAQ: 

Q1: What are the benefits of a coreless hydraulic filter design?
A: A coreless filter, like the 938993Q, allows for easier disposal and recycling. Since the permanent metal core remains in the filter housing, only the media element is replaced, significantly reducing hazardous waste volume.

Q2: How does the β1000 rating affect component lifespan?
A: A β25 = 1000 rating means the filter captures 99.9% of particles 25 microns or larger. This high efficiency is essential for protecting high-pressure pumps from catastrophic failure due to particle accumulation.

Q3: Can this filter handle fire-resistant hydraulic fluids?
A: Yes. Because this model features Viton (FKM) seals, it is compatible with HFD-type phosphate ester fluids and other fire-resistant lubricants that would typically degrade standard nitrile seals.

Q4: When should the 938993Q filter element be replaced?
A: Replacement is recommended when the differential pressure indicator reaches the pre-set limit (usually 1.5 to 2.5 bar) or during scheduled fluid analysis every 500-1000 operating hours.

Q5: Is customization available for specific flow rates or media types?
A: Yes. We offer OEM/ODM services including private labeling, custom micron ratings (1µ to 100µ), and varied seal materials (EPDM/Nitrile) to meet specific project requirements.
