Product Information

Full details

This Festo Compressed Air Filter Regulator is designed for industrial applications requiring clean, regulated compressed air. It is ideal for operators who need a reliable, integrated solution for filtration and pressure control in a compact unit, saving space and simplifying pneumatic systems. A key caveat is that manual draining requires user intervention. The product combines a high nominal flow rate of 5600 l/min with precise pressure regulation (0.3-7 bar) and efficient 5 µm filtration, ensuring optimal performance for sensitive pneumatic equipment.

Extended Product Information

FAQs

What is the filtration grade of this unit?

The Festo Compressed Air Filter Regulator features a filtration grade of 5 µm, effectively removing particles and condensate.

What is the adjustable pressure range?

The pressure regulation range is adjustable from 0.3 bar to 7 bar.

How do I adjust the output pressure?

You can adjust the output pressure by turning the lockable rotary knob. Pull the knob up to adjust, and push it down to lock the setting.

What is the maximum flow rate?

The standard nominal flow rate for this unit is 5600 l/min.

How is the condensate removed?

The condensate is removed via a manual drain valve located at the bottom of the polycarbonate bowl. This requires periodic manual operation.

What are the operating temperature limits?

The unit can operate within an ambient temperature range of -10°C to +60°C.

Can this unit be used for low-pressure applications below 0.8 bar?

No, the minimum operating pressure for this filter regulator is 0.8 bar.

Troubleshooting

No air pressure at output

Check if the input pressure is within the operating range (0.8-10 bar). Ensure the rotary knob is not set to zero or locked. Verify the manual drain valve is closed.

Pressure fluctuates significantly

Ensure the primary pressure (inlet) is higher than the set secondary pressure (outlet). Check for leaks in the system. The directly actuated diaphragm design minimizes hysteresis, but extreme demand changes can cause minor fluctuations.

Condensate not draining

Manually open the drain valve to release accumulated liquid. If the valve is stuck, inspect for debris or damage and clean or replace the valve if necessary.

Unit is leaking air

Inspect all connections, including the G1/2 port and pressure gauge port, for tightness. Check the seals on the bowl and regulator assembly. If leaks persist, internal components may require service or replacement.

Pros and Cons

Pros

  • Space-saving dual functionality (filter and regulator)
  • High flow capacity suitable for many industrial uses
  • Precise and stable pressure regulation
  • Effective particle and condensate removal
  • Secure and adjustable pressure settings

Cons

  • Manual drain requires regular user attention
  • Minimum operating pressure of 0.8 bar may limit some low-pressure applications
  • Maximum ambient operating temperature of +60°C limits use in extreme heat
  • Requires G1/2 pneumatic connection, limiting compatibility with other sizes without adapters

Setup, Compatibility & Care

Setup: Mount the filter regulator in the compressed air line using the G1/2 pneumatic connection. Ensure the airflow direction arrow on the unit matches the air supply. Connect a pressure gauge to the 1/2 in pressure gauge port if needed. Adjust the desired output pressure using the lockable rotary knob. Manual drain activation requires periodic opening of the drain valve to remove accumulated condensate.

Compatibility: This unit uses a G1/2 pneumatic connection. Ensure your existing piping and fittings are compatible. The operating pressure range is 0.8 to 10 bar (minimum 0.8 bar operating pressure), and it operates effectively within an ambient temperature range of -10°C to +60°C.

Care: Regularly inspect the polycarbonate bowl for condensate buildup and manually drain as needed by opening the drain valve. Clean the exterior of the unit with a damp cloth; avoid abrasive cleaners. Periodically check the filter element for clogging and replace if necessary according to manufacturer recommendations. Ensure the lockable knob mechanism is free of debris.
