About the Airtac GAFC Air Service Unit GAFC400N15LNW
This GAFC400N15LNW is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator bolts on beside them. Air enters the 1/2in port, gets filtered to 5 um, and is regulated down to the lower 0.15-0.4 MPa (20-58 psi) band before the lubricator adds a metered oil mist last. The nylon bowls hold 100 cc for condensate and 185 cc for oil, and the whole unit weighs 1810 g.
The lower-pressure regulator tops out at 0.4 MPa, so this suits machines that never need more than 58 psi. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, giving the regulator room to work. The 5 um element traps finer particles than the standard 40 um grade, which protects precision valves but means more frequent element service.

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 GAFC400N15LNW Is Used
Precision valve control
The 5 um element and lower 0.4 MPa range suit a pneumatic valve manifold on a packaging line where fine particles could jam spools and the actuators only need 40 psi.
Low-pressure assembly jigs
Feed a multi-station assembly fixture with 1/2in drops where each station runs a small cylinder at 0.3 MPa. The 185 cc oil bowl keeps lubricators topped up across a full shift.
Instrument air bench
Supply a test bench with regulated air at 0.35 MPa for calibration fixtures. The 5 um filtration protects sensitive gauges, and the nylon bowl suits a clean indoor environment.
Is the Airtac GAFC Air Service Unit GAFC400N15LNW the Right Air-Prep Unit?
The GAFC400 body with a 1/2in port sits between the GAFC300 (3/8in, 1020 g) and the GAFC500 (3/4in, 1910 g). The catalogue flow curve for the GAFC400 is plotted to 6000 L/min at 0.7 MPa inlet, about 70% more than the GAFC300's 3500 L/min envelope. The nylon bowl is a build choice - the common specification (1.0 MPa max, -5 to 70 C) is identical across PC, metal and nylon, so confirm the material suits your surroundings. The semi-auto drain dumps condensate each time pressure drops, with a manual drain for on-demand use. No gauge is supplied with the N code; the 1/4in gauge connection is ready for one if you add it later. The PT thread carries an MPa/psi scale if a gauge is fitted. The 5 um element is the finer filtration option. Spare parts are orderable separately as the GAFR400-15 filter & regulator and the GAL400-15 lubricator. Since this unit adds oil mist, choose a plain GAFR filter-regulator instead if your line must stay oil-free. The 100 cc condensate bowl holds about 67% more than the GAFC300's 60 cc, so this body needs less frequent draining.
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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1810 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 GAFR400-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400N15LNW FAQ
This F.R.L. combination operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the oil bowl 185 cc. Recommended lubricant is ISO VG 32. The complete unit weighs 1810 g.
The N after the port code means no gauge is supplied with the unit. The GAFC400 body has a 1/4in gauge connection, so you can add a circular gauge later if you need to read the set pressure. Without a gauge, you cannot verify the outlet pressure visually, so plan to add one if your process requires monitoring.
