The AirTAC GC40015ALC2G AirTAC F.R.L. Combination G1/2 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 PT1/2" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015ALC2G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one complete air-treatment set. This size 400 configuration is built with G1/2 (BSPP) ports, a 40 um filter element, and an automatic drain on the filter bowl, so collected condensate is expelled without manual attention. The regulator is the low-pressure type and carries a round external gauge reading in psi, and the unit ships with a mounting bracket fitted. The polycarbonate bowls suit the standard working range, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GC combination family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8" to 1". Across the range you can specify thread options (PT standard, G or NPT to order), drain types, filter grades and gauge scales. Because AirTAC publishes flow for these units as curves rather than a single rated figure, we confirm the datasheet and flow figures for your application on request.

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.

Installed at the drop feeding a pneumatic press or clamp station, the set removes water and chips from the supply air, holds a steady low-pressure setting at the ram, and mists oil into the air feeding the cylinders and valves.
Mounted on the manifold serving an assembly line's impact wrenches, nutrunners and air ratchets, the combination cleans the shop air, regulates the tool supply pressure and keeps the tool motors lubricated through the shift.
Fitted in the air-preparation cabinet of packaging and case-sealing machinery, the unit conditions the supply for the machine's valves and actuators, with the automatic drain handling condensate and the psi gauge giving operators a visible line-pressure check.
Start with size and port: the GC series steps through sizes 200 / 300 / 400 / 600, and the 400 size here carries 1/2" ports - step up or down according to the flow your line needs, and ask us to confirm the flow curve against your demand before ordering. The filter element is the 40 um standard grade; a 5 um element is available as the W option if finer particulate removal is required. The automatic drain on this model suits unattended installations; manual and differential-pressure drains are the other catalogue choices. The regulator in this code is the low-pressure type, so confirm the control band suits your circuit - the standard-type GC units carry the published 0.15-0.9 MPa (20-130 psi) auto-drain range. The round gauge here reads in psi; embedded square gauges and MPa or bar scales are the alternatives. Thread is G (BSPP) on this code - PT is the standard thread and NPT is also an order option - and a mounting 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 the GC series as curves rather than a single rated figure, so we do not quote one number here. Tell us your line pressure and the flow your application needs, and we will confirm the sizing against the datasheet curves on request before you order.
The L in the code GC40015ALC2G marks the low-pressure regulator variant, intended for circuits where the working pressure sits below the standard type's normal band; the exact range for this variant is not published, so confirm it with us against your setpoint. The A in the code is the automatic drain: the filter bowl expels collected condensate on its own, so no manual draining is needed in normal service.
