Coreless Filter Elements for High-Efficiency Depth Filtration
Designed for reliable filtration, easy replacement, and flexible housing compatibility
SINFT coreless filter elements are designed to replace traditional metal-core cartridges by eliminating the internal metal support tube.
Only the filter media is replaced during maintenance, delivering lower weight, easier handling, reduced waste, and improved sustainability for modern hydraulic systems.
Installation & Replacement (Flexible Customization Supported)
SINFT coreless filter elements can be flexibly adapted to different housing designs based on the customer's system configuration and operating conditions, ensuring easy installation and stable, reliable operation.
Coreless filter elements can be integrated into different housing configurations:
Support-tube-assisted installation
In certain housing designs, the filter element is installed over a fixed internal support tube, ensuring precise alignment and allowing the element to be easily removed and replaced during maintenance.
Self-supporting installation
In systems without internal support tubes, the coreless element maintains structural integrity on its own and is secured through the housing's end-cap or compression mechanism.
OEM Replacement Coverage
SINFT Can Provide Coreless Filter Replacements For:
- Parker GMF series
- Pall coreless filter designs
- UFI eco-design filter systems
- Other OEM coreless filter platforms (on request)
If you have an OEM part number, SINFT can provide cross-reference verification and replacement solutios.
Key Advantages
- Lightweight coreless design
No internal metal core, significantly reduced weight for easier handling and replacement. - True depth filtration with graded media structure
Contaminants are captured throughout the full media thickness, preventing surface blockage and ensuring stable efficiency. - High dirt-holding capacity for extended service life
Deep filtration structure increases contaminant retention and reduces replacement frequency. - Low and stable pressure drop at high flow rates
Optimized media density maintains low ΔP throughout the element's service life, improving system efficiency. - Metal-free, adhesive-free construction
Enhanced chemical compatibility with no corrosion risk.
SINFT Replacement for Parker GMF Series Coreless Filters
The Parker GMF series features a patented eco-friendly design where the bypass valve and support core are integrated into the filter bowl as reusable components, reducing waste by up to 50%.
Key design features include:
- Integrated reusable bypass valve and support core
- Secure locking system to keep the element in place during maintenance
- Extremely compact filter housing with minimal clearance
- Glass fiber filter media for long service life and stable efficiency
SINFT provides fully compatible replacement coreless filter elements for GMF series housings, maintaining identical installation logic and filtration performance.
