The AirTAC GC40015MC2WK AirTAC F.R.L. Combination, PT1/2, 5 um 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC40015MC2WK is a three-piece AirTAC F.R.L. combination: a filter, a pressure regulator and an oil-mist lubricator, each in its own body and joined as one air-preparation set for 1/2 in (PT1/2) pipework. This configuration carries a 5 um filter element (code W) with a manual drain on the filter bowl, a standard regulator adjustable from 0.05 to 0.9 MPa (7-130 psi), a fitted round pressure gauge reading in psi, a reverse/check valve on the regulator, and a mounting bracket. The polycarbonate bowls suit non-freezing compressed air from -5 to 70 C, with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600, with port options from 1/8 to 1 in, PT (standard), G or NPT threads, automatic, manual or differential-pressure drains, 40 um or 5 um filtration, and gauge scales in MPa, psi or bar. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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 0.05 - 0.9 MPa (7 - 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: GF400-15 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 impact wrenches, nutrunners and air ratchets at assembly stations, where the 5 um element protects tools from fine particulate, the regulator holds a steady working pressure and the lubricator mists oil into the tool air supply.
Preparing air for conveyor diverters, case erectors and packaging cylinders on a production line, with the reverse/check valve helping hold the downstream pressure setting and the manual drain bled during scheduled line cleaning.
A point-of-use set at a maintenance bench or jig station, supplying spray guns, air clamps and small cylinders from a shop compressor, with the psi round gauge giving a direct local reading of the set pressure.
Start with the port size: this 400-size unit is supplied with PT1/2 connections, and the GC series steps through sizes 200 to 600 as port and flow capacity rise. Choose the drain to match maintenance access: this unit has a manual drain, which needs periodic bleeding by hand; automatic and differential-pressure drains are available on other codes. Filtration here is the finer 5 um element (code W) instead of the 40 um standard, which suits downstream equipment that is sensitive to finer particulate. The fitted round gauge reads in psi; MPa and bar scales are offered on other codes. Thread is PT as standard, with G (BSPP) and NPT as order options, and the mounting bracket is included.
Because flow for the GC series is published as curves and not as a single rated number, send us your application details and we will confirm the 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 GR400-15 regulator with a GF400-15 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 l/min or SCFM number. Send us your application details and we will confirm the datasheet flow curves and sizing for this 400-size, PT1/2 unit before you order.
The M in the code selects a manual drain on the filter bowl: collected water and contaminant are released by hand, so the bowl needs periodic bleeding as part of routine maintenance. If you prefer unattended drainage, GC codes with automatic or differential-pressure drains are available in the same size range.
