The AirTAC B52-GFC Copper-Free Air Source Treatment Component B52-GFC40010ANWK 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 automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).
GFC40010ANWK is a genuine AirTAC two-unit F.R.L. set from the G series: a size 400 filter-regulator plus a lubricator, adding a reverse check valve (K) so the downstream circuit is protected against backflow through the set. The code decodes to PT3/8 ports, a 5 um filter element (W), automatic condensate drain (A), the standard regulator type and no gauge. The size 400 bowls are polycarbonate, maximum working pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C, non-freezing. With the automatic drain fitted, the regulator adjustment range is 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part from a series spanning sizes 200 to 600 with ports from 1/8 to 1 inch. The same set can be ordered with a 40 um element, a differential-pressure or manual drain, an embedded square or external round gauge in MPa, psi or bar scales, with or without the check valve, and with G (BSPP) or NPT threads as catalogue options. AirTAC publishes flow as curves rather than a single rated figure, so we confirm the datasheet and flow curve 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.

| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Conditions the air supply to quarter-turn pneumatic actuators on a process line, while the reverse check valve stops backflow through the set if the upstream supply is lost.
Installed at the drop from a compressor ring main into a work cell to give that cell its own filtered, regulated and lubricated air supply with backflow protection.
Feeds gripper and slide cylinders on a pick-and-place unit; the check valve guards the circuit against reverse flow and the automatic drain keeps the bowl clear in continuous duty.
Size 400 sits mid-range in the 200/300/400/600 steps, matched here to PT3/8 ports; move up or down a size when your flow and pipework call for it. This unit is specified with the automatic drain (against the default differential-pressure or manual alternatives) and the 5 um element (against the 40 um standard), plus the K suffix that fits the reverse check valve for backflow protection. Thread is PT as standard, with G (BSPP) and NPT as catalogue options, and gauges in MPa, psi or bar scales can be added where no gauge is wanted here. Because flow is published as curves rather than one 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, 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.
There is no single rated figure to quote: AirTAC publishes flow for the GFC series as curves. Ask us for the datasheet and we will confirm the flow curve and size the unit against your application before you order.
PT is the standard thread on this unit. G (BSPP) and NPT are catalogue options selected by the trailing letter of the code, so tell us which thread your pipework uses and we will quote the correct suffix.
