The AirTAC B52-GFC Copper-Free Air Source Treatment Component B52-GFC40010C1WK 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 PT3/8" ports, a 5 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).
GFC40010C1WK is a two-piece AirTAC G-series air-treatment set: a 400-size filter-regulator paired with a lubricator, delivering filtration, pressure regulation and oil-mist lubrication from one 3/8 in (PT) connection. This configuration carries a 5 um filter element, a differential-pressure drain on the filter bowl, an external round pressure gauge reading in MPa, and a reverse (check) valve that helps hold the regulated downstream pressure against upstream dips.
It is a genuine AirTAC part. The G-series is made in 200, 300, 400 and 600 sizes with 1/8 to 1 in ports, PC (polycarbonate) bowls on the 200-400 sizes and aluminium alloy bowls at 600, a maximum working pressure of 1.0 MPa (145 psi) and a -5 to 70 C temperature range on compressed air. Flow is published as curves rather than one rated figure, so ask us and we will 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 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: GFR400-10 filter regulator and GL400-10 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.

Filtered, regulated and lubricated air for the hydraulic-free pneumatic clamps and tool-change cylinders on a CNC machining center, with the check valve helping the set downstream pressure survive supply-line dips.
A point-of-use set on the drop leg feeding impact wrenches and nutrunners at an automotive assembly cell, where the 5 um element protects tools and the lubricator keeps mist oil in the air stream.
Air preparation for the pick-and-place cylinders and sealing jaws of a carton packaging machine, with the MPa round gauge giving the operator a visible set-point reference.
Size 400 with a 3/8 in PT port sits in the middle of the G-series range: step up to 600 or down to 300/200 depending on the flow your line needs - the published curve, not a single rating, decides. The 5 um element (W option) suits finer air-quality duties; the standard element is 40 um. Drain here is the differential-pressure default, and the regulator adjusts over 0.15-0.9 MPa (20-130 psi); automatic (A) and manual (M) drain versions are also catalogue options. The gauge is the external round type on an MPa scale; embedded square gauges and psi or bar scales can be ordered, and PT is the standard thread with G (BSPP) and NPT available as options.
Because flow figures are published as curves and not a single rated number, send us your required flow and working pressure 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR400-10 filter regulator on its own.
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not quote one number here. Tell us the flow and working pressure your application needs and we will confirm the correct size against the datasheet on request before you order.
GFC pairs the filter-regulator with the lubricator in two pieces, while GC uses three separate filter, regulator and lubricator bodies. Both filter, regulate and lubricate. If you need filtering and regulating only, with no oil mist, the single-body GFR is the closer match.
