The AirTAC GC40015LF2W 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015LF2W is an AirTAC GC series three-unit F.R.L. combination: a separate filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This configuration is the size 400 unit with a PT1/2 port, the 5 um filter element (code W) for finer water and particulate removal than the standard 40 um grade, a differential-pressure drain on the filter bowl, the low-pressure regulator type, and a fitted embedded square gauge scaled in psi. The bowls on this size are polycarbonate (PC), and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, with choices of drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge scale (MPa, psi or bar) and thread (PT standard, with G and NPT as order options). Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeds spray guns and air-assisted applicators on a paint line, where the 5 um element gives finer water and particulate removal, the regulator holds the gun supply steady and the lubricator mists oil into the air stream.
Prepares the air feeding pick-and-place and clamp cylinders along a packaging conveyor: filtered, regulated and lubricated air in one set at a 1/2 inch PT connection.
Supplies workholding clamps and pneumatic actuators on a CNC machine cell, with the low-pressure regulator type suiting circuits that hold a reduced setpoint and the square psi gauge giving a local pressure readout.
Start with the size and port step: size 400 with a PT1/2 port sits in the middle of the GC range (200/300/400/600, ports 1/8 to 1 inch), and the right step depends on the air demand of the circuit it feeds - we can check the published flow curves against your application before you order. This unit is already configured with the 5 um element (W) instead of the 40 um standard, the differential-pressure drain (the default, which bleeds the bowl as pressure drops), and the low-pressure regulator type - choose the standard type instead if your circuit runs at ordinary main-line setpoints. The fitted square gauge reads in psi; MPa and bar scales are alternatives, and an external round gauge is optional. Thread is PT as standard; G (BSPP) and NPT are order options. Mounting bracket is included. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
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, Cv or SCFM number. Send us your application details and we will confirm the flow data from the datasheet and check the sizing for you on request.
The W in the code GC40015LF2W selects the 5 um element instead of the 40 um standard grade, giving finer removal of water and particulate - useful where downstream valves and actuators see dirtier shop air. The drain is the differential-pressure type (the default), which bleeds accumulated condensate from the PC bowl as system pressure drops; automatic and manual drains are available as alternative configurations in the series.
