Filter efficiency＞99%

Filter Rating: 4 Micron, 5 Micron and larger.

Traps more contaminants before they enter lubricating system for improved generator performance

Imported from Italy Ahlstrom

Italy Ahlstrom filter materrial has better strength, burst resistance and stiffness, the filter paper folding distance is more uniform, results in higher dust holding capacity and longer span life than normal filter material

Synthetic fiber material

The filter efficiency of normal cellulose or cellulose and glass fiber mixed material is around 75% at 20 Micron and life span is around 6,000 miles, while our synthetic fiber material is 99% at 4 Micron and 12,000 - 20,000 miles
