About the Airtac GAC F.R.L. Unit GAC300C15ASK
Delivering cleaned, regulated and lubricated air for mid-size pneumatic setups, this GAC300C15ASK assembly integrates a filter, regulator and lubricator on a single L-shape bracket with quick mounting clamps. The 1/2in port pairs with a 40 um element and a standard pressure range of 0.15-0.9 MPa (20-130 psi). Air passes through the filter first, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never gets fouled.
This specific configuration uses a robust metal bowl and an automatic drain that clears condensate without an operator, making it well-suited for wet lines or unattended machinery. A circular gauge is fitted to read the set pressure in MPa/psi for the default PT thread. The unit also includes a reverse-flow (reflux) valve, which the catalogue shows as a separate pneumatic symbol with details on its own page.

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 GAC300C15ASK Is Used
Automotive Assembly Lines
Feeds multiple pneumatic wrenches and actuators on a vehicle production line, relying on the automatic drain to handle condensate during continuous shift operations.
Carton Sealing Machines
Provides stable pressure and oil mist to moving cylinder parts in high-speed packaging equipment, preventing premature wear during extended runs.
Material Handling Systems
Conditions air for diverter gates and sorting cylinders on warehouse conveyors, where the metal bowl withstands occasional accidental impacts.
Is the Airtac GAC F.R.L. Unit GAC300C15ASK the Right Air-Prep Unit?
Choose this 1300 g assembly when a mid-size body is required; it offers a 60 cc condensate bowl and 98 cc oil bowl, meaning fewer interventions than a smaller GAC200 unit. The metal bowl provides a durable option for harsher environments, while the automatic drain handles liquid removal independently. If the downstream line must remain completely oil-free, this lubricator must be omitted and a separate filter-regulator chosen instead. Replacement parts follow the same body-port suffix, so you can order GAF300-15, GAR300-15 and GAL300-15 individually rather than replacing the whole assembly.
The catalogue flow curve for the GAC300 is plotted to 3000 L/min at 0.7 MPa inlet, which is exactly half of the GAC400's 6000 L/min envelope, helping you size up or down. Because the maximum supply is 1.0 MPa and this standard type regulates to 0.9 MPa, there is only about 0.1 MPa of headroom above the top setting, so plan a supply near 1.0 MPa if you truly need 0.9 MPa out.
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 GAC300C15ASK FAQ
This standard type operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It has a 1/2in port, a 60 cc drain bowl, a 98 cc oil bowl, a 40 um element, and weighs 1300 g. The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32.
The K indicates that a reverse-flow (reflux) valve is fitted to this unit. The official catalogue displays this as a distinct pneumatic symbol with further details located on its own dedicated page.
