The AirTAC B52-GFC Copper-Free Air Source Treatment Component B52-GFC300C08AC1WK 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).
GFC300C08AC1WK is a genuine AirTAC G-series two-unit combination: a GFR300 filter-regulator paired with a GL300 lubricator, providing filtration, pressure regulation and oil-mist lubrication from one 1/4 in (PT1/4) connection. This build adds the K option, a reverse (check) valve fitted on the regulator side. It also has an automatic drain on the filter bowl, a 5 um (W) filter element and a round external pressure gauge in MPa. Maximum inlet pressure is 1.0 MPa (145 psi) and, with the automatic drain, the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). Medium is compressed air only; operating range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFC two-unit family spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, 40 um standard or 5 um (W) elements, automatic, manual or differential-pressure drains, round or square gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow for the G series is published as curves rather than a single rating, so ask us and we will confirm the datasheet for this exact model 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: GFR300-C0 filter regulator and GL300-C0 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.

Conditioning the supply to the gate and diverter cylinders along a sorting conveyor, where the fitted check valve and regulator keep downstream pressure stable and the automatic drain removes condensate from a unit mounted along the line without a shutdown for draining.
Feeding a shared drop that runs pneumatic nutrunners and screwdrivers in an assembly cell: the 5 um element keeps grit out of the tools, the lubricator mists oil into the air stream, and the MPa round gauge lets the cell technician set tool pressure at a glance.
Supplying regulated, lubricated air to a leak-test or functional-test bench, where the check valve holds the set condition on the fixture side and the automatic drain suits a bench fed from a compressor receiver that sees frequent condensate carryover.
This is the same 300-size, PT1/4 (1/4 in) two-unit set as the non-K version, with the K reverse (check) valve fitted as built; the plain version is available without it. Choose the size by air demand and port: GFC runs from size 200 at 1/8 in up to size 600 at 1 in. The automatic drain here suits unattended positions; manual and differential-pressure drains exist at the same size. The 5 um (W) element is finer than the 40 um standard, and the gauge is the round external type in MPa; square-gauge (F) versions and other scales are in the family. The 300-size bowls are polycarbonate (PC).
Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. Because AirTAC publishes G-series flow as curves rather than a single rating, send us your pressure and demand and we will confirm sizing against the curve 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 GFR300-C0 filter regulator on its own.
Yes. AirTAC publishes flow for the G series as curves rather than a single rated figure, so there is no single rated number to quote. Send us your working pressure and air demand and we will confirm the flow curve and the full datasheet for this model on request.
K is the reverse-valve code: this set is built with a reverse (check) valve fitted on the regulator side. The otherwise identical code without the K is supplied without it, so choose the K version when you want the check valve as part of the unit rather than added separately.
