Airtac GAC F.R.L. Unit GAC300C15SN
The AirTAC Airtac GAC F.R.L. Unit GAC300C15SN 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 1/2" ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC300C15SN
Delivering cleaned, regulated and lubricated air for mid-size pneumatic setups, this GAC300C15SN unit integrates a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port pairs with a 40 um element, while the standard pressure range spans 0.15-0.9 MPa (20-130 psi). Air passes through the filter first, then the regulator, with oil mist added last so the internal regulator seat never fouls.
This specific configuration uses a robust metal bowl and omits the pressure gauge entirely. Without a gauge fitted, the set pressure cannot be read unless one is added later to the 1/8in gauge connection. The assembly weighs 1300 g, meaning it requires proper panel or frame mounting rather than relying on downstream tubing for support.

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 GAC300C15SN Is Used
Assembly Line Tooling
Feeds a bank of pneumatic screwdrivers and clamps on an automotive assembly line, providing steady 0.6 MPa pressure and oil mist for tool longevity.
Carton Sealing Machines
Conditions air for continuous motion packaging equipment, trapping 40 um particulates before they reach fast-cycling cylinder valves.
Material Handling Diverters
Supplies clean, lubricated air to diverter actuators on a parcel sorting conveyor, ensuring moving parts receive consistent oil mist.
Is the Airtac GAC F.R.L. Unit GAC300C15SN the Right Air-Prep Unit?
Choose this 1/2in port body for duties needing more flow than a GAC200, as the catalogue flow curve for the GAC300 is plotted to 3000 L/min at 0.7 MPa inlet compared to 1750 L/min for the smaller body. The metal bowl suits harsher plant environments where polycarbonate might be at risk, though the -5 to 70 C operating temperature floor rules out unheated winter outdoor lines. It carries a semi-auto and manual drain pair, dumping condensate on pressure drops or on demand. Because the lubricator adds oil mist downstream, select a separate filter-regulator if the line must remain oil-free. Replacement spares share the 300-15 suffix: GAF300-15, GAR300-15 and GAL300-15. Keep in mind the 1.5 MPa proof pressure provides a 1.5x burst-test margin over the 1.0 MPa maximum, which is a safety rating rather than permission to operate above the standard ceiling.
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 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 1300 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 GAC300C15SN FAQ
This F.R.L. combination operates at 0.15-0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It functions in -5 to 70 C temperatures, uses a 40 um element, and weighs 1300 g. The drain bowl holds 60 cc and the oil bowl holds 98 cc, requiring ISO VG 32 or equivalent lubricant.
The N after the port in the model code indicates no gauge is supplied. To monitor the set pressure, an operator must add a separate circular gauge to the 1/8in gauge connection on the regulator body.
