8. FAQ (Frequently Asked Questions)

Q1: What filtration precision grades are available for the PFC series?

A: Standard options include 2.5μm, 5μm, 7μm, 12μm, and 22μm. Selection depends on your system cleanliness requirements 

and component sensitivity. All grades achieve β ≥ 1000.

Q2: What is the significance of β ≥ 1000?

A: Beta ratio (β) indicates filtration efficiency. β = 1000 means the filter captures 99.9% of particles at the rated micron size, 

ensuring effective contaminant control.

Q3: Can the PFC cart handle fire-resistant fluids like phosphate ester or water-glycol?

A: Yes. With appropriate seal material selection (FKM for phosphate ester, compatible seals for water-glycol), the PFC series 

is suitable for both fluid types. Please specify your fluid type when ordering.

Q4: How do I know when to replace the filter elements?

A: The PFC series is equipped with an audible-visual differential pressure alarm. When the alarm activates, element 

replacement is required. The built-in bypass valve prevents flow interruption if replacement is delayed.

Q5: Can the PFC cart be used while the hydraulic system is running?

A: Yes. The PFC series is designed for offline (bypass) filtration—connect it to the system while equipment continues normal 

operation. This is the most common application mode.

Q6: What is the maximum flow rate of the PFC series?

A: The PFC series offers rated flow capacities from 25 L/min to 400 L/min, with multiple models available to match your

 specific system requirements.

Q7: What power supply is required for the PFC cart?

A: Standard configuration is AC380V/50Hz. Other voltage/frequency options (e.g., 460V/60Hz) are available upon request 

for international applications.

Q8: Is the PFC cart suitable for continuous 24-hour operation?

A: Yes. The PFC series is designed for continuous industrial use with appropriate maintenance. Monitor differential pressure

 regularly during extended operation.

Q9: Can the PFC cart be used outdoors?

A: Yes, within the 0–80°C operating temperature range. The anti-corrosion coated frame provides protection for outdoor use.

 Protect electrical components from rain and moisture.

Q10: What is the motor power range for different flow models?

A: Motor power ranges from 0.75 kW for small (25–50 L/min) models to 15 kW for large (300–400 L/min) models. Exact ratings

 depend on flow rate and operating pressure.

Q11: Does the PFC cart include a suction strainer?

A: Yes. A suction strainer is standard equipment, protecting the pump from large contaminants that could cause damage.

Q12: What spare parts should I keep in stock for the PFC cart?

A: We recommend keeping a complete set of replacement filter elements for your precision grade, spare suction strainers, 

and replacement hoses. Seal kits are also recommended for longer-term inventory.

Q13: Are the filter elements interchangeable with other Pall filter housings?

A: PFC series elements are Pall-specific design and are fully interchangeable with original Pall PFC filter housings. Always use 

genuine Pall-compatible replacement elements for guaranteed performance.

Q14: Do you offer custom configurations for the PFC series?

A: Yes. Custom flow rates, filtration precision, power supply configurations, and material options are available upon request.
