Airtac BFC: series F.R.L Pneumatic Air Filter - BFC3000MLNG

The AIRTAC BFC3000MLNG is a B Series compressed-air preparation unit that combines a filter regulator and lubricator in one compact assembly. It filters compressed air, separates moisture, regulates downstream pressure, and supplies oil-mist lubrication to compatible pneumatic components.

This model features a G3/8 port, manual drain, low-pressure regulator with a maximum adjustable pressure of approximately 0.4 MPa, and no pressure gauge.

The AIRTAC BFC3000MLNG is suitable for industrial automation equipment, packaging machinery, pneumatic fixtures, assembly lines, and other low-pressure pneumatic systems requiring lubricated air.

AIRTAC BFC3000MLNG Model Number Explained

Each part of the BFC3000MLNG model number identifies a specific product configuration:

• BFC: B Series filter regulator and lubricator combination

• 3000: 3000 body size with a 3/8-inch port

• M: Manual drain

• L: Low-pressure type, adjustable up to approximately 0.4 MPa

Main Functions

Compressed-Air Filtration

The BFC3000MLNG filters solid particles from compressed air and separates part of the condensed moisture. This helps prevent contaminants from entering pneumatic cylinders, mechanical valves, and other downstream components.

The standard filtration rating is generally 40 μm, making the unit suitable for general industrial air preparation.

Low-Pressure Regulation

The low-pressure regulator provides controlled air pressure for pneumatic equipment operating at up to approximately 0.4 MPa.

Its push-to-lock adjustment mechanism helps prevent accidental pressure changes caused by vibration or external contact. Because this model does not include a pressure gauge, an appropriately rated external gauge is recommended for accurate adjustment.

Oil-Mist Lubrication

The integrated lubricator introduces a controlled oil mist into the downstream airflow. It can provide continuous lubrication for compatible pneumatic cylinders, mechanical valves, and air-operated actuators.

A transparent inspection dome makes it easier to monitor the oil drip rate. AIRTAC recommends ISO VG32 pneumatic lubricant or an equivalent oil.

Manual Condensate Drainage

The BFC3000MLNG uses a manual drain. Operators should inspect the filter bowl regularly and discharge accumulated condensate before it reaches an excessive level.

Key Product Features

• Combines filtration, pressure regulation, moisture separation, and lubrication

• Compact two-piece construction saves installation space

• G3/8 BSPP parallel-thread connection

• Low-pressure design with a maximum setting of approximately 0.4 MPa

• Push-to-lock regulator knob helps prevent unintended pressure changes

• Low pressure loss and effective moisture separation

• Transparent bowls simplify water and lubricant level inspection

• Visible oil-drip adjustment

• Manual drain for straightforward routine maintenance

• Modular construction supports convenient installation and replacement

Typical Applications

The AIRTAC BFC3000MLNG can be used in:

• Industrial automation systems

• Packaging and filling machinery

• Electronic assembly equipment

• Pneumatic clamps and fixtures

• Printing and labelling machines

• Light industrial machinery

• Pneumatic control cabinets

• Low-pressure cylinder systems

• Lubricated mechanical valves

• Pneumatic actuators requiring oil-mist lubrication

Why Choose the AIRTAC BFC3000MLNG?

The BFC3000MLNG is designed for pneumatic systems that use a G3/8 connection, operate at pressures up to approximately 0.4 MPa, and require downstream oil-mist lubrication.

Compared with a standard-pressure BFC3000 configuration, the “L” version is intended for lower-pressure applications. Its manual drain is appropriate for installations where routine inspection and maintenance are available.

The no-gauge configuration may also suit systems that already use centralized or externally mounted pressure monitoring.

Selection Guide

Before purchasing the AIRTAC BFC3000MLNG, confirm the following:

1. The system connection is G3/8.

2. The required outlet pressure is within the low-pressure regulator range.

3. Manual condensate drainage is acceptable.

4. Downstream pneumatic components require oil-mist lubrication.

5. An external pressure gauge is already installed or will be added.

6. The required airflow is within the capacity of the BFC3000 body size.

7. The operating temperature and environment comply with the product requirements.

G3/8, PT3/8, and NPT3/8 are different thread standards. They should not be treated as interchangeable solely because they share the same nominal port size.

Installation and Maintenance

• Install the unit according to the airflow arrow marked on the body.

• Keep the filter and lubricator bowls in a vertical downward position.

• Use an external pressure gauge when adjusting the outlet pressure.

• Lock the regulator knob after completing the pressure adjustment.

• Inspect and manually drain accumulated condensate regularly.

• Clean or replace the filter element at suitable maintenance intervals.

• Use ISO VG32 or an equivalent pneumatic lubricant.

• Do not overfill the lubricator bowl.

• Do not remove the bowl while the system is pressurized.

• Protect the bowls from incompatible chemicals and corrosive environments.

• Prevent condensate from freezing inside the unit.

Frequently Asked Questions

What is the AIRTAC BFC3000MLNG?

The AIRTAC BFC3000MLNG is a compressed-air preparation unit combining a filter regulator and lubricator. It filters the air, separates moisture, regulates outlet pressure, and supplies oil-mist lubrication.

What is the port size of the BFC3000MLNG?

It has a G3/8 port, also described as a 3/8-inch BSPP parallel pipe thread.

Does the BFC3000MLNG include a pressure gauge?

No. The “N” in the model number indicates that the product is supplied without a pressure gauge. An external gauge is recommended when setting the outlet pressure.

What is its maximum adjustable pressure?

The “L” designation identifies a low-pressure configuration with a maximum adjustable pressure of approximately 0.4 MPa. Consult the product label or current technical documentation for the exact regulating range.

Does it have an automatic drain?

No. The “M” designation means that it uses a manual drain.

What is the standard filtration rating?

When no optional fine-filtration code is included, the standard filtration rating is generally 40 μm.

Which lubricant should be used?

AIRTAC recommends ISO VG32 pneumatic lubricant or an equivalent oil. Engine oil, hydraulic oil, and unsuitable high-viscosity lubricants should not be used as substitutes.

Does every pneumatic system need a lubricator?

No. Oil-free cylinders, precision instruments, proportional valves, and applications requiring clean, oil-free air may not be suitable for an air-line lubricator. Always check the lubrication requirements of downstream equipment.
