The AirTAC GC400-15ALF2GK AirTAC F.R.L. Combination, G1/2 is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT1/2" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC400-15ALF2GK is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one supply unit. This size 400 configuration is built with a G1/2 (BSPP) port, a 40 um filter element, an automatic drain on the filter bowl, a low-pressure type regulator, an embedded square gauge scaled in psi, a reverse/check valve, and a mounting bracket. The polycarbonate bowls let you see condensate and oil level at a glance, and the automatic drain ejects collected water without manual attention. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8" to 1", and options include manual or automatic or differential-pressure drains, a 5 um filter element (code W), alternative gauge scales (MPa/psi/bar) and PT or NPT threads in place of G. Because flow is published as curves rather than a single rating, ask us and we will confirm the flow and datasheet figures for this model against your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF400-15 filter, GR400-15 regulator and GL400-15 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Feeds spray guns and air-fed respirator stations on a paint line, where filtered, regulated and lightly oiled air at a controlled low pressure keeps finish quality consistent across the booth.
Supplies the clamp, seal and pusher cylinders on a carton-forming and wrapping line, with the automatic drain keeping condensate out of the valves during multi-shift running.
Conditions the shop-air feed to a machining centre's pneumatic tool changer, clamps and air-blast circuit, protecting the machine's valves from water and debris while lubricating actuator seals.
Start with the port and flow step: size 400 with a 1/2" port suits lines with substantial cylinder and valve consumption, while sizes 200/300 cover lighter duty and size 600 covers the heaviest - match the size to the required flow, which we can confirm from the published curves before you order. This unit has the automatic drain (code A), which suits unattended or hard-to-reach installations; manual and differential-pressure drains are available if you prefer operator-controlled or load-proportional draining. The 40 um element is the standard grade for general pneumatic supply; specify the 5 um W grade where downstream valves or instruments need finer filtration. The low-pressure type regulator (code L) is intended for circuits running at reduced working pressure - its exact adjustment range is not published, so confirm it with us for your setpoint. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is G (BSPP) here, with PT and NPT available to order, and the bracket is included.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for this family as curves rather than a single rated figure, so we do not quote one number. Send us your application's flow and pressure requirements and we will confirm the sizing from the datasheet before you order.
The L code in GC400-15ALF2GK marks the low-pressure version of the regulator, intended for circuits that run at reduced working pressure rather than full line pressure. Its exact adjustment range is not published in the catalogue, so confirm your setpoint with us and we will verify suitability from the datasheet. The unit also carries a reverse/check valve (K) and an automatic drain (A).
