Spiral Perforated Metal – Center or Outer Tubes
Bypass valve is installed on the spin-on fuel and oil filter. When the filter element is blocked and the oil pressure reaches 100±20 kPa, the bypass valve will automatically open to allow the oil to flow through.
- Stable function throughout the service life
- Valve pressure is suitable for engine parameter requirements
- The bypass valve can also play a role at low temperatures (anti-frost) and keep it completely sealed;
- Provide the best fuel supply for the engine.

HEPA Filter Support Mesh – Internal & External
HEPA filters, which stand for High Efficiency Particulate Air filters, are advanced air filters designed to remove small particles and contaminants from the air. They are highly efficient in capturing airborne particles as small as 0.3 micrometers with a high efficiency rate of 99.97%.
During HEPA filter production, the HEPA filter support mesh provides support and protection for filter media.
Perforated Metal for Hydraulic and Air Filters
Perforated metal mesh is made of galvanized or stainless steel plates, which has excellent corrosion resistance performance for long term use. Perforated metal mesh has rigid structure and long service life to protect filters from transformation. It is widely used as inner support mesh or outer protective mesh of truck air filter, car air filter, eco fuel and oil filters and hydraulic filters.
Hot Melt Glue – EVA, PO & PA Types
Air Filter Gluing, Filter Element Gluing, Filter Element Gluing, Filter Paper Bonding, Filter Paper Bonding, Filter Materials, Process Management
Hot melt glue, also called hot melt adhesive is widely used in air filters and oil filters for bonding, shaping and assembling in the production process. Because hot melt glue is environmental protection and fast curing, which can increase production efficiency. Different filter applications have different requirements for the characteristics and materials of filter hot melt glue. Commonly used filter hot melt glue include EVA, PO (Polyolefin), PA (Polyamide), etc. And PA hot melt glue is especially used for oil-resistant and high-temperature filtration.
Rubber Sealing Rings – Wear and Aging Resistance
The rubber sealing ring is made of silica gel. It is used for spin-on filters and heavy duty air filters to ensure that the filter and the engine body are tightly connected. It can help filters resist changing pressure, mechanical loads and ensure that will not cause leakage even under extreme temperatures.
