2. Product Performance – Precision, Capacity, and Reliability

High Filtration Precision

The PFC series offers optional filtration ratings of 2.5, 5, 7, 12, and 22 microns, 

all with β≥1000 per ISO 16889 standards. This ensures highly efficient capture of 

both large debris and sub-micron particles, effectively controlling oil contamination 

levels and protecting sensitive hydraulic and lubrication components from abrasive wear.

Wide Flow Range

With rated flows spanning from 25 to 400 L/min, the PFC series includes multiple models to 

accommodate systems of varying capacities. From small machine tool hydraulic circuits to

 large turbine lubrication loops, there is a PFC model precisely matched to your flow requirements,

 ensuring high purification efficiency without compromising system pressure or circulation rates.

Large Dirt-Holding Capacity

Utilizing advanced glass fiber and composite filter media, PFC filter elements

 offer superior clogging resistance and extended service life. High dirt-holding capacity 

translates to fewer element change-outs, reduced consumable costs, and less maintenance

 downtime – a significant advantage in continuous-operation facilities.

Complete Safety Protection

Every PFC filter cart is equipped with comprehensive safety features:

· Built-in bypass valve – prevents system flow interruption in the event of element saturation

· Differential pressure alarm – provides visual/audible warning when element replacement is 

due

· Phase loss protection – safeguards the motor against electrical faults and misoperation

· Overload protection – prevents pump damage under abnormal operating conditions

 pressure of 1.6 MPa. This robust pressure rating meets the demands of industrial oil transfer,

circulation, and filtration applications, including those with elevated line pressures.

Power Supply

Standard configuration is AC380V/50Hz, with motor power ranging from 0.75 kW to 15 kW 

depending on the selected flow model. All motors are rated for continuous industrial duty 

and matched to pump requirements for optimal energy efficiency.

· Frame construction: Heavy-duty carbon steel with anti-corrosion coating, ensuring 

durability in harsh workshop and outdoor environments

· Operating temperature range: 0°C to 80°C

· Fluid compatibility: Suitable for mineral oils and a wide range of fire-resistant fluids,

 including water-glycol and phosphate ester types

Structural Configuration

Each PFC filter cart is mounted on a mobile frame equipped with heavy-duty casters for

 easy positioning. Standard configuration includes:

· Suction strainer for initial coarse protection

· Vent and drain ports for convenient maintenance

· Audible-visual differential pressure alarm for immediate operator notification

· Quick-connect inlet/outlet fittings for rapid system hookup
