This air preparation combination unit offers comprehensive compressed air treatment in a compact 4...This air preparation combination unit offers comprehensive compressed air treatment in a compact 40 mm width. It features a G1/4 pneumatic connection, 1400 l/min standard nominal flow rate, and 4-10 bar pressure regulation range. The integrated 40 µm filter ensures efficient contaminant removal, while the precise regulator maintains stable pressure with minimal hysteresis. This unit combines a soft start valve, shut-off valve, and filter regulator with pressure gauge, providing a complete solution for reliable pneumatic system performance. The drain type is manual and the filtration size is 40µm. The pressure gauge port thread size is 1/4 in, with a maximum ambient operating temperature of +50°C and a minimum operating pressure of 0.8bar. The ambient operating temperature range is -0 to +50°C and the bowl material is plastic.
This Festo MS Filter Regulator is designed for industrial applications requiring comprehensive compressed air treatment in a compact 40 mm width. It's ideal for users needing reliable pneumatic system performance with integrated filtration, pressure regulation, and safety features. A potential caveat is the manual drain, which requires periodic user attention. Key features include a 40 µm filter, G 1/4 pneumatic connection, 1400 l/min flow rate, and a pressure regulation range of 4-10 bar.

Extended Product Information
FAQs
What is the filtration level of this unit?
The filtration level is 40 micrometers (40 µm).
What is the maximum flow rate?
The standard nominal flow rate is 1400 liters per minute (l/min).
How do I adjust the output pressure?
You can adjust the output pressure by turning the black knob on top of the regulator. Push the knob down to lock the setting.
How often should I drain the filter bowl?
The frequency depends on the humidity of your compressed air supply and system usage. It is recommended to check and drain the bowl regularly, for example, at the end of each shift or daily.
Can I install a pressure gauge with this unit?
Yes, this unit features a G 1/4 port specifically for pressure gauge installation.
What is the pressure range this regulator can handle?
The pressure regulation range is from 4 to 10 bar.
Does this unit require electrical power?
No, this is a pneumatic component and does not require electrical power to operate.
Troubleshooting
No air output from the unit.
Ensure the shut-off valve is open and the inlet air supply is connected and pressurized. Check that the flow direction is correct.
Inability to regulate pressure to the desired level.
Verify the inlet pressure is above the set outlet pressure. Check for leaks in downstream components. Ensure the regulator knob is properly adjusted.
Excessive water in the filter bowl.
Ensure the manual drain is functioning correctly and is operated regularly. Check for significant moisture in the incoming compressed air supply.
Soft start valve not engaging properly.
Confirm the system is not already pressurized before startup. Check for any obstructions in the soft start mechanism.
Pros and Cons
Pros
Combines multiple air preparation functions (filter, regulator, soft start, shut-off) into a single unit, saving space and installation time.
Offers reliable protection for pneumatic equipment with its 40 µm filter.
Provides stable and adjustable air pressure suitable for a wide range of applications.
Compact design makes it suitable for crowded control cabinets or machine footprints.
Includes essential safety features like a shut-off valve and soft start.
Cons
Manual drain requires regular operator attention to prevent condensate buildup.
The 40 µm filtration may not be sufficient for extremely sensitive applications requiring finer filtration.
Maximum ambient operating temperature of +50°C limits use in very high-temperature environments.
Minimum operating pressure of 0.8 bar means it's not suitable for very low-pressure systems.
Setup, Compatibility & Care
Setup:
Identify the correct flow direction indicated on the unit.
Connect the compressed air supply to the inlet port (G 1/4).
Connect the downstream pneumatic device to the outlet port (G 1/4).
Install a pressure gauge (if desired) into the designated gauge port.
Adjust the regulated pressure using the regulator knob, typically after ensuring the system is under load.
Compatibility:
Pneumatic Connection: G 1/4 thread size.
Operating Pressure: Suitable for systems operating between 0.8 and 10 bar.
Temperature: Ambient operating temperature range of -0 to +50°C.
Care:
Filter Maintenance: Periodically inspect the filter bowl for accumulated condensate. Manually drain the bowl by opening the manual drain valve when necessary.
Cleaning: Clean the exterior of the unit with a slightly damp cloth. Avoid using solvents or abrasive cleaners.
Inspection: Regularly check the pressure gauge (if installed) and connections for any signs of leaks or damage.
