About the Airtac GAFC Air Service Unit GAFC300N15ASNW
This GAFC300N15ASNW is an F.R.L. combination built as a filter-regulator body plus a separate lubricator on a shared T bracket. Air enters the 1/2" port, gets filtered by the 5 um element, and is regulated to a standard 0.15-0.9 MPa (20-130 psi) range before the lubricator adds a controlled oil mist downstream.
The nylon bowl holds 60 cc of condensate while the oil bowl holds 98 cc, and the whole unit weighs 1020 g. Since no gauge is fitted, the 1/8" gauge connection is available if you want to add one later. The automatic drain clears water without an operator, making this a low-attention choice for a continuous production line.

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 GAFC300N15ASNW Is Used
Precision Valve Control
The 5 um element protects pilot-operated solenoid valves on a stamping press from fine particulate, while the regulated output keeps actuation consistent.
Continuous Assembly Line
On a multi-station assembly machine, the automatic drain removes condensate without stopping production, and the 98 cc oil bowl keeps lubricators running between shifts.
Machine Tool Lubrication
A CNC lathe's way-lubrication system benefits from the metered oil mist added after filtration and regulation, protecting slideways without over-oiling.
Is the Airtac GAFC Air Service Unit GAFC300N15ASNW the Right Air-Prep Unit?
Choose this GAFC300N15ASNW when you need a 1/2" port with a finer 5 um element for sensitive valves or instruments. The nylon bowl is a build choice, but the common specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm it suits your environment. The automatic drain handles wet lines, while the standard S type covers 0.15-0.9 MPa (20-130 psi) for most actuators. Since the gauge is omitted, plan to read pressure via the 1/8" connection if needed. The PT thread comes with an MPa/psi scale if you add a gauge. Spares are orderable as GAFR300-15 and GAL300-15. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan your inlet pressure accordingly.
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 GAFC300N15ASNW FAQ
The standard pressure range is 0.15-0.9 MPa (20-130 psi). Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). Operating temperature is -5 to 70 C. The drain bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32. The unit weighs 1020 g.
The N after the port code means no gauge is supplied. The GAFC300 body has a 1/8" gauge connection, so you can fit a separate gauge there if you need to read the set pressure. This keeps the unit compact when pressure is set once and left alone.
