The AirTAC B52-GFC Copper-Free Air Source Treatment Component B52-GFC30010MC1WK 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 manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).
GFC30010MC1WK is a genuine AirTAC G-series two-unit set combining a filter regulator with a lubricator on a 3/8 in PT ported line, and the trailing K code adds a reverse (check) valve in the regulator section. The M code sets a manual drain on the filter bowl, C1 selects the external round gauge with an MPa scale, and W fits the 5 um filter element instead of the standard 40 um. With manual drainage, the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi); for the exact behaviour of the K-option check valve in your circuit, we confirm the details from the datasheet on request.
The medium is compressed air, maximum working pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C (non-freezing); at size 300 the bowls are polycarbonate (PC). The GFC family spans sizes 200 to 600, with automatic or differential-pressure drains, the standard 40 um element, embedded square or external round gauges on MPa, psi or bar scales, and G (BSPP) or NPT threads available as catalogue options. Flow is published as curves, not a single rated figure, so we confirm sizing and datasheet figures 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 0.05 - 0.9 MPa (7 - 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: GFR300-10 filter regulator and GL300-10 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.

Used where a clamped workpiece must stay pressed if shop air dips: the check valve in the regulator section backs up the downstream setting while the set keeps the clamp cylinder filtered, regulated and lubricated.
Feeds the pilot-air circuit for line valves and actuators, where the 5 um element protects sensitive pilot spools and the check valve isolates the pilot branch from upstream disturbances.
Mounted at the panel feeding jig and fixture cylinders, giving the setter an MPa gauge reading, clean regulated air, oil mist for the cylinders and check-valve isolation of the panel circuit.
This code differs from GFC30010MC1W only in the K suffix, which fits a reverse (check) valve - choose it where the downstream circuit must not simply empty back through the set. Size 300 with the 3/8 in port is the mid step (200 to 600, 1/8 in to 1 in); we verify the step against the published flow curves for your demand before you order. The manual drain allows regulation from 0.05 to 0.9 MPa (7-130 psi) but needs a routine bleed, while automatic and differential-pressure drain codes start at 0.15 MPa (20 psi). The 5 um element serves finer point-of-use air than the standard 40 um, the C1 round gauge reads in MPa, and thread is PT as standard with G (BSPP) and NPT as orderable options. Ask us to confirm sizing against the flow curves 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 GFR300-10 filter regulator on its own.
AirTAC publishes G-series capacity as flow curves, not as one rated number, so we do not quote a figure here. Tell us your line pressure and air demand and we will confirm the correct size and the full datasheet figures on request before you order.
The K suffix means a reverse (check) valve is fitted in the regulator section of this set, which distinguishes it from the plain GFC30010MC1W. For the exact role it plays in your circuit, we confirm the details from the datasheet on request.
