3. Performance Characteristics

Aite DPF Series High Pressure Filter delivers superior performance through the following key characteristics:

3.1 Pollution Transmitter for Maintenance Indication

Aite DPF Series High Pressure Filter is equipped with a pollution transmitter (visual or electrical signal indication) – providing 

clear indication when the filter element is blocked by pollutants, allowing maintenance personnel to replace the filter

 element promptly and avoid unexpected downtime.

3.2 High-Performance Glass Fiber Filter Element

Aite DPF Series High Pressure Filter filter element is made of glass fiber material folded – offering the advantages of high

 filtration accuracy, large oil flow, small original pressure loss, and large contaminant capacity.

3.3 Multiple Filtration Accuracy Options

Aite DPF Series High Pressure Filter offers glass fiber filtration accuracy of 3, 5, 10, and 20μm; metal mesh filtration accuracy 

of 25, 50, 100, and 200μm – allowing selection based on system cleanliness requirements.

3.4 BH and BN Filter Element Options

Aite DPF Series High Pressure Filter high pressure filter element is divided into BH (high pressure difference) and BN 

(low pressure difference) two kinds – providing flexibility for different operating conditions.

3.5 Cleanable Metal Mesh Option

Aite DPF Series High Pressure Filter metal mesh filter element can be cleaned – reducing replacement frequency and 

maintenance costs.

3.6 Compact Integrated Design

Aite DPF Series High Pressure Filter features an integrated valve block design with oil inlet and outlet on the same plane

 at the upper end – simplifying installation and saving space.

Aite DPF Series High Pressure Filter offers equivalent performance to genuine parts at 40%–60% lower cost – making it

 an ideal choice for cost-conscious maintenance programs without compromising system protection.

4. Working Principle

Aite DPF Series High Pressure Filter operates with a pollution transmitter (visual or electrical signal indication) that 

provides signal indication when the filter element is blocked by pollutants – allowing maintenance personnel to replace 

the filter element promptly. The filter element is made of glass fiber material folded, which has the advantages of high 

filtration accuracy, large oil flow, small original pressure loss, and large contaminant capacity.
