The AirTAC Airtac GFC Combination Unit GFC400C15AF1W is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with See datasheet ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).
GFC400C15AF1W is an AirTAC G-series two-unit air preparation set: a filter regulator combined with a separate lubricator, so one assembly removes water and particulate, regulates pressure and meters oil mist to downstream actuators. The W suffix specifies the finer 5 um filter element instead of the standard 40 um. This configuration is the size 400 body with PT1/2 ports, an automatic drain on the filter bowl and an embedded square pressure gauge reading in MPa. The polycarbonate bowl is standard at this size, the set takes compressed air at up to 1.0 MPa (145 psi) inlet, the regulator adjusts from 0.15-0.9 MPa (20-130 psi) with automatic drain, and working temperature is -5 to 70 C.
This is a genuine AirTAC part. The G series covers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include the standard 40 um grade, manual or differential-pressure drains, NPT or G (BSPP) threads and a reverse/check valve (K). AirTAC publishes flow as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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 set has no separate bracket code — the two 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 set. Constituent units, orderable separately as spares: GFR400-C1 filter regulator and GL400-C1 lubricator.
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Conditions air feeding spray guns and atomizing air lines in a paint booth, where the 5 um element supports cleaner air to the finishing equipment and the lubricator is set for the downstream circuit needs.
Supplies regulated, filtered and lubricated air to pneumatic transmitters and indicator devices on a process instrument panel.
Prepares air for the roller-setting cylinders and clutch-brake circuits on an offset printing press, with automatic drain keeping condensate off the controls.
Size 400 with 1/2 inch PT ports is the mid-to-large step in the G series; move to size 300 or 600 as flow demand changes. Drain choice here is automatic, with manual and differential-pressure drains as catalogue alternatives. This W version carries the 5 um element; drop the W to order the standard 40 um grade. The gauge is the embedded square type with MPa scale; other scales and an external round gauge are options. PT thread is the standard, with G (BSPP) and NPT available as ordered specifications. Because AirTAC publishes flow as curves and not as one rated number, 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR400-C1 filter regulator on its own.
Flow for the G series is published as performance curves, not as a single rated figure, so we do not state a number here. Share your line pressure and consumption profile and we will confirm the datasheet curves and sizing on request.
The W suffix orders the 5 um element, which suits downstream equipment that is sensitive to finer particles; the standard 40 um grade suits general plant air. The drain type, gauge and thread choices are independent of the filter grade in the code.
