Airtac GAC F.R.L. Unit GAC20008SK
The AirTAC Airtac GAC F.R.L. Unit GAC20008SK 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 1/4" ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC20008SK
Delivering cleaned, regulated and lubricated air for single actuators or small jigs, the GAC20008SK is a three-unit F.R.L. combination pre-plumbed on a single L-shape bracket. This assembly processes air through a 40 um filter, a pressure regulator and a lubricator in that strict sequence, ensuring oil mist is introduced downstream of the regulator seat so it never fouls the internal mechanisms. The 1/4in port and 750 g weight place it firmly in the compact size class, making it ideal for tight installations where panel space is at a premium.
This specific configuration features a PC bowl and a semi-auto plus manual drain pair, requiring an operator to manage the 25 cc condensate bowl. A circular gauge is fitted, reading MPa/psi to match the default PT thread, allowing operators to monitor the set pressure directly. The code includes a reverse-flow (reflux) valve, which the catalogue shows as a separate pneumatic symbol with details on its own page. If the downstream line must remain oil-free, omit the lubricator and choose a dedicated filter-regulator instead.

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 GAC20008SK Is Used
Small Pneumatic Jigs
Feeds single-acting cylinders and clamping jigs on benchtop assembly stations, providing the exact oil-misted air needed for low-friction movement.
Pick-and-Place Heads
Conditions air for compact robotic grippers, ensuring the 40 um filter captures debris that would otherwise jam small valve spools.
Benchtop Testing
Regulates supply for laboratory air bearings or small test fixtures, where the fitted gauge allows precise visual confirmation of pressure.
Is the Airtac GAC F.R.L. Unit GAC20008SK the Right Air-Prep Unit?
When sizing this unit, note that the GAC200 body with its 1/4in port offers a plotted flow curve up to 1750 L/min at 0.7 MPa inlet, whereas stepping up to the GAC300 body roughly doubles that envelope to 3000 L/min. The semi-auto drain dumps condensate on every pressure drop, while the manual option allows on-demand emptying of the 25 cc bowl. The 40 um element suits general pneumatic duties, but a 5 um variant is available for precision instrument air. Because the three units are separately orderable, a clogged element or damaged bowl does not require replacing the whole assembly; simply order the GAF200-08, GAR200-08 or GAL200-08 spares as needed. The maximum supply is 1.0 MPa and the Standard type regulates to 0.9 MPa, so there is only about 0.1 MPa of headroom above the top setting.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 25 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 750 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 GAC20008SK FAQ
This standard type unit regulates from 0.15-0.9 MPa (20-130 psi) and has a max pressure of 1.0 MPa (145 psi) with a 1.5 MPa (215 psi) proof pressure. It operates from -5 to 70 C, weighs 750 g, and features a 25 cc drain bowl alongside a 36 cc oil bowl. The recommended lubricant is ISO VG 32 or equivalent.
The K denotes that a reverse-flow (reflux) valve is attached to the unit. The official catalogue illustrates this as a distinct pneumatic symbol and directs users to its own page for specific functional details.
