The AirTAC Airtac GAC F.R.L. Unit GAC400N10ALN 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 3/8" ports, a 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).
Delivering cleaned, regulated and lubricated air for mid-size pneumatics, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 3/8in port pairs with a 2390 g mass, placing it firmly in a size class that requires a proper panel or frame mount rather than tubing support. Air passes through the filter first, then the regulator, with oil mist added last so the internal seat never fouls.
Configured for low-pressure duties, the unit regulates between 0.15-0.4 MPa (20-58 psi) and uses a 40 um element. The nylon bowl holds 100 cc of condensate and 185 cc of oil, while the automatic drain clears liquid without an operator. Because the N follows the port, no pressure gauge is supplied; the 1/4in gauge connection remains available if you need to add one later.

Specifications follow the official AirTAC GAC catalogue (pages 216-217). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAC400 is 1/4" if you add one.

Constituent units, orderable separately as spares: GAF400-10 filter, GAR400-10 regulator, GAL400-10 lubricator — all three share this body and port.
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.

Feeds delicate bagging and sealing actuators where operating pressures must stay below 0.4 MPa to prevent crushing product.
Conditions air for sensitive benchtop valves and grippers, providing steady low-pressure output without manual condensate draining.
Supplies a consistent 3/8in air flow to looms and tensioners, adding the required oil mist for high-speed moving spindles.
Choose this configuration when a machine needs precise low-pressure control, as the L type tops out at 0.4 MPa. If the equipment might ever demand more, the standard S type is the correct choice instead. The automatic drain suits unattended or wet lines, and the nylon bowl offers a lightweight alternative to the metal or PC options within the same 1.0 MPa maximum pressure limit. Since no gauge is included, the set pressure cannot be read without adding one to the 1/4in connection. Remember that oil mist is added downstream, so select a separate filter-regulator if the line must remain oil-free. Should a component fail, order the GAF400-10, GAR400-10 and GAL400-10 spares rather than replacing the whole assembly. Stepping up from the GAC300 increases the plotted flow envelope from 3000 to 6000 L/min at 0.7 MPa inlet, a 2x ratio for higher demand. Keep in mind that 0.4 MPa is 44% of the standard 0.9 MPa ceiling.
Quick checklist
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.
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). The operating temperature is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 100 cc, the oil bowl holds 185 cc, and the unit weighs 2390 g.
The N after the port in the model code indicates that no circular gauge is supplied. You can install your own gauge using the 1/4in gauge connection on the body to monitor the 0.15-0.4 MPa range.
