Pall PFC Series Oil Filter Carts – Mobile High-Efficiency Oil Purification Units

Product Performance and Key Features

Filtration Precision

The PFC series supports optional filtration ratings of 2.5, 5, 7, 12, and 22 micrometres, 

all achieving a Beta ratio of 1000 or higher. This ensures stable and reliable contaminant removal,

 effectively controlling oil contamination levels. The high precision protects sensitive components

 such as servo valves, pumps, and bearings from particle-induced wear, extending the service life 

of both oil and equipment.

Wide Flow Range

The series offers rated flow capacities from 25 to 400 litres per minute, with multiple model

 options to match different system capacities. Whether servicing a small hydraulic station or a 

large lubrication loop, users can select the appropriate flow rating to optimize purification

 efficiency without overloading the system.

High Dirt-Holding Capacity

Using advanced glass fibre and composite media, the filter elements provide strong clogging 

resistance and extended service life. High dirt-holding capacity means fewer element change-outs,

 lower consumable costs, and reduced maintenance downtime, making long-term operation more

 economical.

Complete Safety Protection

Each unit is equipped with a built-in bypass valve to prevent system flow interruption, 

even when the element becomes fully loaded. A differential pressure alarm provides audible or 

visual indication for timely element replacement. Phase loss protection prevents motor damage

 caused by power supply irregularities, ensuring safe and reliable operation under industrial 

conditions.

Ease of Operation

The filter cart is designed with user-friendly controls, including a visible pressure gauge and 

differential pressure indicator. The quick-connect hose fittings enable fast setup and connection 

to different oil systems. Operation requires minimal training, allowing plant personnel to deploy

 the unit quickly without specialized supervision.

Technical Specifications

Working Pressure: The rated operating pressure is 1.0 MPa, with a maximum allowable pressure

 of 1.6 MPa. This meets the requirements for most industrial oil transfer and filtration applications, 

including high-viscosity oils and long-distance pumping.

Power Supply: Standard configuration is AC380V, 50Hz. Motor power ranges from 0.75 kW to 15 kW 

depending on the flow model, providing adequate drive for all rated flow capacities.

Materials and Construction: The frame is constructed from carbon steel with an anti-corrosion

 coating, ensuring durability and resistance to oil spills and workshop moisture. The unit is 

designed for an operating temperature range of 0°C to 80°C, making it suitable for both indoor and 

outdoor deployment. The system is compatible with mineral oils, water-glycol fluids, and

phosphate ester fire-resistant fluids.

Structural Configuration: The mobile frame is fitted with swivel casters for easy maneuverability.

 Standard components include a suction strainer to protect the pump from large debris, vent and

 drain ports for system maintenance, and an audible-visual differential pressure alarm for operator 

notification.

Scope of Application

Pall PFC series oil filter carts are widely used across multiple industrial sectors:

Metallurgy: Purification of hydraulic oil in rolling mills, continuous casting machines, and forging 

presses, where high contamination loads are common.

Petrochemical: Filtration of lubrication oil in compressors, pumps, and turbines, as well as 

pre-filtration of new oil before system filling.

Power Generation: Oil cleaning for steam turbines, gas turbines, and transformer oil systems, 

where water and particle contamination must be strictly controlled.

Construction Machinery: On-site oil filtration for excavators, loaders, and cranes, helping extend

 equipment life in harsh working conditions.

Wind Energy: Maintenance of gearbox lubricating oil and hydraulic pitch control systems, 

where oil cleanliness directly impacts turbine reliability.

Hydraulic and Lubrication Systems: Suitable for hydraulic stations, industrial gearboxes, 

steam turbine lubrication, and pump stations. Capable of filtering hydraulic oil, lubricating oil, 

gear oil, water-glycol, and phosphate ester fire-resistant fluids.

Economic and Operational Benefits

The PFC series offers measurable returns through multiple channels:

· Extended oil service life reduces the frequency and cost of full oil changes

· Lower filter element consumption reduces replacement frequency and consumable costs

· Reduced equipment wear prevents costly repairs and production interruptions

· Improved production efficiency shortens downtime for oil maintenance

· Flexible deployment eliminates the need to purchase fixed systems for each piece of equipment

Frequently Asked Questions

Q1: Can the same filter cart be used for different types of oil?

A1: Yes. The PFC series is compatible with mineral oils, water-glycol fluids, and phosphate ester

 fire-resistant fluids. However, it is recommended to avoid switching between significantly different

 oil types without thorough cleaning to prevent cross-contamination.

Q2: How do I determine the correct filtration rating for my application?

A2: The selection depends on system requirements. For servo-valve-controlled systems, 2.5 or 5

 micrometres is recommended. For standard industrial hydraulics, 7 to 12 micrometres is typically 

sufficient. For pre-filtration of new oil or coarse systems, 22 micrometres is suitable.

Q3: How often should the filter element be replaced?

A3: Replacement is triggered by the differential pressure alarm or when the indicator reaches the 

specified change-out level. Actual frequency depends on the contamination load of the oil being

 filtered. Regular monitoring ensures optimal performance.

Q4: Can the unit run continuously for extended periods?

A4: Yes. The motor is designed for continuous operation. However, periodic checks of oil 

temperature, system pressure, and element condition are recommended during long-running 

sessions to ensure safe operation.

Q5: What accessories are included with the standard unit?

A5: Standard units include suction and discharge hoses with quick couplings, a pressure gauge, 

a differential pressure indicator, and an operating manual. Additional accessories such as custom

 hose lengths, special adapters, and transportation covers are available upon request.
