The AirTAC GC40015ALC2WK AirTAC F.R.L. Combination, PT1/2 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 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC400 series is a three-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled to deliver clean, regulated and lubricated compressed air from one supply point. This configuration, GC40015ALC2WK, is built with PT1/2 ports, a 5 um filter element (code W, against the 40 um standard), an automatic drain on the filter bowl, a low-pressure type regulator, an external round gauge scaled in psi, and a reverse/check valve fitted. The filter and lubricator bowls are polycarbonate at this size, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual draining, 40 um or 5 um filtration, gauge style and scale options, and PT, G or NPT threads. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Feeding spray-booth and paint-gun air drops where water and particulate must be stripped to 5 um, pressure is held at a low set point, and a fine oil mist is needed to keep air motors and trigger valves running smoothly.
Conditioning the air feeding cylinder-driven case packers, sealers and conveyor diverters, where the automatic drain keeps condensate off the bowls during long unattended shifts and the check valve holds the circuit against back-flow.
Supplying a manifold that serves impact wrenches, grinders and clamping fixtures, giving each station filtered, low-pressure-regulated and lubricated air from a single 1/2 inch drop with a psi gauge for local setting.
Start with the port step: this unit is the 400 size with PT1/2 ports, one step above the 300 series; match the size to the air demand of the line and step up if your flow curve needs headroom. The 5 um element (code W) suits points of use that need finer particulate and water removal than the 40 um standard; keep the 40 um grade where general protection is enough. The automatic drain empties the filter bowl without manual attention, which suits unattended or elevated installations; manual and differential-pressure drains remain available elsewhere in the range. The regulator here is the low-pressure type; its exact adjustment range is not published in the material we hold, so confirm it with us against your set pressure before ordering. The round gauge is scaled in psi; square embedded gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G and NPT available to order, and the bracket is included in this code.
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 series as curves, not as a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the datasheet and flow-curve figures on request, and help you check whether the 400 size at PT1/2 matches your demand before you order.
The L in the code marks the low-pressure type of regulator, intended for circuits set below standard working pressures; its exact adjustment range is not published in our material, so confirm it with us against your set point. The A marks an automatic drain, which expels collected condensate from the filter bowl without manual intervention - useful where the unit is mounted in a hard-to-reach position or runs unattended.
