Airtac GAC F.R.L. Unit GAC500N20LN
The AirTAC Airtac GAC F.R.L. Unit GAC500N20LN is a genuine three-unit F.R.L. combination — a filter, a pressure regulator and a lubricator pre-assembled on one bracket with quick mounting clamps. It has 3/4" ports, a 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAC F.R.L. Unit GAC500N20LN
Delivering cleaned, regulated and lubricated air for larger pneumatic setups, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. It features a 3/4in port and a 40 um element. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator, preventing fouling of the regulating seat.
This specific unit carries a lower pressure type, governing output between 0.15-0.4 MPa (20-58 psi). The nylon bowl equips the assembly with a 108 cc condensate capacity and a 225 cc oil reservoir, meaning fewer interventions compared to a smaller body. No gauge is supplied, but a 1/4in connection is provided if you need to add one later.

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 GAC F.R.L. Unit GAC500N20LN Is Used
Low-Force Assembly Lines
Feeds multiple low-pressure actuators on automotive interior clip installation stations where delicate insertion forces are required.
Thin-Film Packaging
Supplies regulated air to flow wrappers and bagging machines that operate soft-grip jaws to avoid puncturing delicate polymer films.
Textile Guiding
Conditions air for pneumatic fabric edge guides and tensioning cylinders in weaving looms that demand steady, low-pressure actuation.
Is the Airtac GAC F.R.L. Unit GAC500N20LN the Right Air-Prep Unit?
Choose this 2460 g assembly for 3/4in lines requiring low-pressure regulation up to 0.4 MPa. It uses a semi-auto and manual drain pair, discharging condensate on pressure drops or on demand. The nylon bowl suits standard -5 to 70 C environments, though you should confirm compatibility for aggressive surroundings. If your downstream line must stay oil-free, select a filter-regulator instead, as this unit adds oil mist. For maintenance, the three units are separately orderable as GAF500-20, GAR500-20 and GAL500-20. Stepping up to the GAC600 body roughly increases the plotted flow envelope from 7000 to 12000 L/min at 0.7 MPa inlet, but choosing this lower-pressure type means the 0.4 MPa ceiling is just 44% of the standard 0.9 MPa maximum.
Quick checklist
- ✓ Body size for your peak flow (3/4" 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 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 108 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 2460 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 filter-regulator instead of an F.R.L. combination on that branch.
Airtac GAC F.R.L. Unit GAC500N20LN FAQ
This lower-pressure type regulates from 0.15-0.4 MPa (20-58 psi). It has a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). Operating temperature is -5 to 70 C. The drain bowl holds 108 cc and the oil bowl 225 cc, with a total weight of 2460 g. The recommended lubricant is ISO VG 32.
No, a gauge is not supplied on this model. The body features a 1/4in gauge connection, allowing you to install a separate pressure gauge reading in MPa/psi to match the default PT thread if visual monitoring of the 0.15-0.4 MPa range is needed.
