The AirTAC GC400C15LF2WG AirTAC F.R.L. Unit G1/2 Low-Pressure 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC400C15LF2WG is a three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator working together to clean, regulate and lubricate compressed air on one 1/2 inch line. This configuration is built for G1/2 (BSPP) ports, carries the fine 5 um filter element (code W) with a differential-pressure drain on the filter bowl, and uses the low-pressure regulator type fitted with an embedded square gauge scaled in psi. No reverse/check valve is fitted, a mounting bracket is included, and the bowl on the filter section is metal. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch. Across the series you can order different drain types (differential-pressure, automatic or manual), a 40 um standard or 5 um fine filter element, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Because flow is published as curves rather than a single rating, we 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. 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.

On a cartoning or wrapping line, the filter strips water and fine particles from the plant air, the low-pressure regulator holds a gentle supply pressure for delicate cylinders, and the lubricator mists oil to keep actuator seals and surfaces working smoothly.
At a bench or robotic assembly cell running air-driven drivers and clamps, this three-unit set cleans the incoming air to 5 um, regulates it at low pressure for the tool circuit, and feeds a controlled oil mist to extend tool life.
On a bottling or food-plant conveyor with air-operated gates and pushers, the combination conditions the line air in one pass: filtered to 5 um, held at the low pressure the gate cylinders need, and lubricated for continuous cycling.
Start with size and port: the 400 size with its 1/2 inch port suits lines where larger flow is needed, while 200/300 sizes cover smaller ports and 600 covers 3/4 and 1 inch. Choose the drain on the filter bowl - differential-pressure (as here, the default), automatic for unattended draining, or manual where an operator drains by hand. Pick the filter grade: 40 um standard or 5 um fine (this unit is the 5 um W grade) where downstream equipment needs cleaner air. Select the gauge scale (MPa, psi or bar) and the thread standard - PT is the AirTAC standard, with G (BSPP) and NPT available as order options. Note that this is the low-pressure regulator type; the exact adjustment range for that type is not published in the summary data, so ask us to confirm it. Flow is published as curves, not a single rating, so 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 curves rather than a single rated figure, so there is no one flow number we can honestly quote. Tell us your line pressure and the air demand of your equipment, and we will confirm the sizing from the datasheet on request before you order.
The W in the code selects the fine 5 um filter element instead of the 40 um standard, and the gauge code selects the embedded square gauge scaled in psi (MPa and bar scales are also available). The low-pressure regulator type and G (BSPP) thread are likewise order choices - PT is the AirTAC standard thread, with G and NPT as catalogue options. Ask us to confirm the low-pressure adjustment range from the datasheet.
