About the Airtac GAFC Air Service Unit GAFC300N15LNK
This GAFC300 F.R.L. combination pairs a filter-regulator body with a lubricator on one T-bracket, so air is cleaned and set to pressure before a metered oil mist is added downstream. The 1/2in port and 1020 g mass place it in the mid-size class, suited to machine headers feeding several actuators rather than a single small cylinder.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 40 um element and a nylon bowl. A circular gauge is not supplied, but the 1/8in gauge connection allows one to be fitted. The reverse-flow valve is included, and the two units are separately orderable as GAFR300-15 and GAL300-15.

Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Where the Airtac GAFC Air Service Unit GAFC300N15LNK Is Used
Precision pressure setting
Use the 0.15-0.4 MPa range to set a consistent low pressure for a delicate pneumatic clamp or a tensioning device on a packaging line, where higher shop pressure would damage the product.
Machine header feed
Feed a 1/2in header on a small assembly machine that powers multiple air cylinders. The 60 cc condensate bowl and 98 cc oil bowl reduce how often an operator must check levels during a shift.
Lubricated actuator circuit
Supply oil-misted air to a reciprocating actuator on a forming press. The lubricator adds ISO VG 32 oil after regulation, keeping the moving parts lubricated without passing oil back through the regulator seat.
Is the Airtac GAFC Air Service Unit GAFC300N15LNK the Right Air-Prep Unit?
Choose the GAFC300 body for 1/2in ported lines needing up to 3500 L/min at 0.7 MPa inlet as shown on the catalogue flow curve. The nylon bowl is a build choice; the shared specification of 1.0 MPa max and -5 to 70 C applies, so confirm it suits your environment. This model has the semi-auto drain that dumps on pressure drop plus a manual drain, and the 40 um element handles standard shop air. The L type tops out at 0.4 MPa, so if your machine may ever need more pressure, select the S type instead. The PT thread and no-gauge configuration mean you must add a gauge to read the set pressure. The reflux valve is fitted per the K code. For oil-free lines, omit the lubricator and choose a plain GAFR300-15 filter-regulator. Max supply of 1.0 MPa leaves about 0.6 MPa above the 0.4 MPa top of the range.
Quick checklist
- ✓ Body size for your peak flow (1/2" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Thread & gauge scale (PT / G / NPT)
Installation & Maintenance Notes
- check Install with the airflow arrow: filter-regulator first, lubricator last.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Fill the oil bowl with ISO VG 32 or equivalent only.
- check Drain condensate before the 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1020 g unit on its bracket, not on the tubing.
The lubricator adds an oil mist downstream of the regulator. If any part of the line must stay oil-free, use a plain GAFR300-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N15LNK FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures, uses ISO VG 32 lubricant, has a 60 cc drain bowl and 98 cc oil bowl, and weighs 1020 g. The 1/2in port and 40 um element suit standard shop air.
The N after the port code means no gauge is supplied. The GAFC300 body has a 1/8in gauge connection, so you can add a circular gauge later to read the set pressure. The PT thread uses an MPa/psi scale if you fit one.
