Cured and Uncured Filter Papers for Air Filters
Filter paper is processed by mixing plant fiber pulp and a little cotton pulp. Because of its fiber structure, leaving numerous tiny holes for liquid particles passing through and leaving solid particles out, which is the basic principle of solid and liquid separation.
- The filter paper can separate impurity particles from the liquid and extend engine and auto service life.
- High filtration efficiency. 98% filtration efficiency of 4 µm particles and 99% filtration efficiency of 6 µm particles.
- Up to 800 L/m2/s air permeability.
- Oil filter paper can withstand up to 600 kPa pressure.
- Up to 70 70 mN/m high stiffness of cured filter paper.
Hot Melt Glue – EVA, PO & PA Types
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.

Metal End Caps for Air & Oil Filters
Metal end caps are mainly used for the end closure of paper (filter cloth) and filter screens of heavy-duty vehicle air filter. The two ends of the filter paper and the filter screen are sealed to ensure that all the gas passes through the filter paper (filter cloth) without short circuit.
- Material: galvanized steel plates.
- Thickness: 0.4/0.5/0.6/0.7 mm
- We can customize metal end caps according to original part number.
