AIRTAC AFR BFR Pressure Regulating Filter

The AIRTAC AFR BFR Pressure Regulating Filter are designed with a lightweight and compact structure, making them easy to install and use. They feature a push-lock mechanism that prevents accidental pressure adjustments, ensuring stable operation. With low pressure loss and high water separation efficiency, these regulators perform reliably in various applications. The transparent viewing window allows users to directly monitor the oil drip rate for easy maintenance. Additionally, a low-pressure model is available, offering a maximum adjustable pressure of 0.4 MPa to meet specific needs. These features make the AFR/BFR Series ideal for achieving precise and efficient pressure control.

AFR Air Filter Regulator Lubricator  FAQs:

1. What happens if the (AFR) air pressure is too high or too low?

Air pressure too high:

It may cause deformation or damage to pipelines and pneumatic components, and may require the equipment to be stopped and restarted.

Air pressure too low:

Air output becomes slow, system efficiency decreases, operation time increases, and energy consumption rises.

Correct pressure regulation is essential for stable pneumatic system operation.

2. Is lubricating oil required for the AFR unit?

Lubricating oil is not mandatory.

Use special pneumatic lubricating oil only

AFR can work normally without oil

Adding oil can extend the service life of pneumatic components

Once lubrication is started, oil supply should not be stopped, otherwise seals may wear abnormally.

3. How to install an AFR air source treatment unit?

The AFR body has IN (air inlet) and OUT (air outlet) markings

Install air fittings according to the arrow direction

Incorrect installation may affect filtration and pressure regulation

The bottom port is for condensate drainage, not air leakage.

4. How does the AFR drain water?

When there is no air pressure, push the drain valve upward to release water

For manual drain type, pull the drain plug downward

After draining, re-pressurize the system to resume normal operation

Regular draining helps maintain clean compressed air.

5. Is the air inlet and outlet direction always the same?

Normally:Left side: air inlet / Right side: air outlet

However, some AFR models support reverse air flow.

Always follow the markings on the product body, not installation habits.

7. What maintenance is required for AFR units?

Clean or replace the filter element regularly

Drain condensed water in time

Lock the pressure adjustment after setting

Check fittings and seals periodically

Proper maintenance ensures long-term stable operation.
