Flame Retardant Wood Pulp Fiber Air Filter Element PU Air Filter

1. Product introduction

PU filter element is also called PU melt blown filter element. The melt blown filter element is made of hot-melt entanglement of polypropylene ultra-fine fiber.

The fiber randomly forms a three-dimensional microporous structure in space. The pore diameter is distributed in a gradient along the filtrate flow direction.

It integrates surface, deep and fine filtration, and can intercept impurities with different particle sizes. Filter element accuracy range: 0.5-100 μ m. Its flux is more than 1.5 times that of the peak room filter element with the same precision. Different types of end cover joints can be configured to meet the needs of various engineering installation.

5. Production process

The filter element processing procedures are: blanking, folding, crimping, clamping, assembling, bonding, and packaging. The bubbling test must be done when the precision is high, and the special structure or material needs to be cured. To

Based on the existing car air filter element, it is possible to directly set up waterproof and breathable between the filter element box and the filter layer to prevent water from entering the paper air filter element, avoiding the increase of resistance and deformation and damage of the filter element after being damp. Improves the service life of the filter element, prevents water from entering the air inlet, avoids engine cylinder rubbing, and improves the safe use efficiency of the engine

6. Do’s and don’ts

First, polypropylene is wound with continuous polypropylene long fiber produced by melt blown process Second, high filtration precision, large flow, uniform structure, large pollutant holding capacity and long service life Third, it has good chemical compatibility, without any additives, and the fiber is not easy to fall off Fourth, it is widely used and cheap.
