The AirTAC GC400C15ALF2 AirTAC F.R.L. Combination PT1/2 Low-Pressure 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400C15ALF2 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one prepared-air station. This configuration is sized 400 with a 1/2 in PT port, and the filter section carries a 40 um element with an automatic drain, so collected water is expelled without manual attention. The regulator is the low-pressure type and is fitted with an embedded square gauge scaled in psi, while the lubricator feeds oil mist downstream to pneumatic tools and cylinders. The filter and lubricator bowls are polycarbonate at this size, and the unit is supplied with a mounting bracket.
This is a genuine AirTAC part from the GC combination range, which is available in sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge scale, and PT, G or NPT thread. Rated flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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-C1 filter, GR400-C1 regulator and GL400-C1 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-assisted applicators on a paint line, where filtered, regulated and lubricated air keeps atomising valves and gun triggers working cleanly through a full shift.
Serves the pneumatic cylinders and vacuum-assist valves on a cartoner or case-packer conveyor, giving one point where operators set line pressure, check the gauge and maintain the oil feed.
Prepares air at a drop feeding impact wrenches, air chisels and clamping fixtures in a machining cell, protecting the tools from water and grit while keeping them oiled in service.
Start with the size and port: the 400 size with its 1/2 in PT port suits lines where larger cylinders or multiple take-offs demand more air than the 200/300 step, while the 600 size covers the biggest ports. Choose the drain to match access: automatic drain (as fitted here) suits enclosed or infrequently attended installations, manual drain suits stations visited daily, and differential-pressure drain is the catalogue default. Filter grade is 40 um as standard for general plant air; specify the W code for 5 um where finer protection is needed. The square gauge here reads in psi; MPa and bar scales are also available, and an external round gauge is an option. Thread is PT as standard, with G and NPT as orderable variants, and a bracket is included for panel or wall mounting. Because rated flow in this series is published only as curves and not a single number, send us your application details and we will confirm sizing against the datasheet before you order.
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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your application and operating pressure and we will confirm the flow from the datasheet on request before you order.
The A in the code GC400C15ALF2 specifies an automatic drain on the filter bowl, which expels collected water without operator attention - useful for enclosed or rarely visited installations. The same series can be ordered with a manual drain or the differential-pressure default instead if your maintenance routine suits that better.
