The AirTAC Airtac GAC F.R.L. Unit GAC400N15ASN 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).
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this AirTAC GAC400N15ASN F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port serves mid-to-high volume duties, while the standard pressure type operates from 0.15-0.9 MPa (20-130 psi). It uses a 40 um element to capture solid grain and moisture before the air reaches downstream moving parts.
Because the N appears after the port code, this specific unit ships without a pressure gauge, though a 1/4in gauge connection is provided if you need to add instrumentation later. The nylon bowl equips the assembly for environments where polycarbonate might not be suitable, and the automatic drain actively expels condensate from the 100 cc bowl without operator intervention. Oil mist is introduced downstream of the regulator, preventing seat fouling and ensuring stable pressure control.

Constituent units, orderable separately as spares: GAF400-15 filter, GAR400-15 regulator, GAL400-15 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 multiple pneumatic presses and robotic arms on a car manufacturing line, providing steady 1/2in air supply with automatic condensate removal for continuous shift operation.
Conditions air for high-speed box folding and taping equipment where consistent pressure and lubrication ensure pneumatic actuators cycle reliably without sticking.
Supplies oil-misted air to diverter gates and pusher cylinders on a beverage bottling conveyor, protecting moving seals from rapid wear during extended production runs.
Choose this 2390 g assembly when a machine frame or panel mount is available, as the body requires structural support rather than tubing suspension. The automatic drain makes it highly suitable for unattended lines or wet environments, saving manual maintenance time compared to the semi-auto and manual drain alternative. If your downstream line must remain strictly oil-free, you should bypass the lubricator stage and select a dedicated filter-regulator instead. Replacement parts follow the same body and port suffix, meaning you can order GAF400-15, GAR400-15 and GAL400-15 individually rather than replacing the whole assembly. Stepping up to the GAC500 body increases the plotted flow envelope from 6000 to 7000 L/min at 0.7 MPa inlet, which is roughly a 17% increase, while dropping to the GAC300 reduces it to 3000 L/min. Keep in mind that the 1.5 MPa (215 psi) proof pressure provides a 1.5x burst-test margin over the 1.0 MPa maximum, but this does not permit running above the stated limit.
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 standard type unit handles air 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 operates in temperatures from -5 to 70 C, uses a 40 um element, and weighs 2390 g. The drain bowl holds 100 cc and the oil bowl holds 185 cc, requiring ISO VG 32 or equivalent lubricant.
The N after the 15 port code indicates no gauge is supplied, but a 1/4in connection is ready for adding one if you need to monitor the 0.15-0.9 MPa range. The N before the port code denotes a nylon bowl, chosen as a build material for specific surroundings rather than the standard polycarbonate.
