The AirTAC B52-GFC Copper-Free Air Source Treatment Component B52-GFC300C08C1WK 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).
The GFC series is AirTAC's two-unit air-treatment set: a filter regulator paired with a lubricator, covering filtration, pressure regulation and oil-mist lubrication in one set. This GFC300C08C1WK is the size 300 body on a PT1/4 port, with a differential-pressure drain on the filter bowl, the 5 um W-grade element in place of the standard 40 um, and a round pressure gauge with MPa scale on the regulator. The trailing K means a reverse (check) valve is fitted, so no separate inline check valve is needed in the branch. It is for compressed air only, rated to 1.0 MPa (145 psi) inlet and -5 to 70 C, with the regulator adjusting between 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The G series comes in sizes 200, 300, 400 and 600 with ports from 1/8 inch to 1 inch; drain type, filter grade, gauge style and scale, thread form (PT as standard, with G and NPT as catalogue options) and the check-valve option are selectable. Flow is published as characteristic curves, not a single rated figure, so we confirm datasheet numbers 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.

Air for the gripper and clamp cylinders on an end-of-line palletiser: the set filters, regulates and lubricates the 1/4 inch branch, and the fitted check valve completes the circuit without a separate inline check.
Supplying the parallel grippers and vacuum ejector valves on a robot picking cell, where the 5 um element suits the sensitive valve stack and the lubricator mists the gripper seals.
Conditioning the 1/4 inch air feeds to loom solenoid valves and doffer cylinders in a weaving shed: one set filters, regulates and lubricates each drop, with the W grade for finer particle removal.
Size 300 on a PT1/4 port fits 1/4 inch branches feeding downstream cylinders and tools; step up to size 400 or 600 if the demand is larger. The 5 um W element is the pick when valves and instruments need finer filtration than the standard 40 um element provides.
This K version carries a reverse (check) valve as part of the set; the same unit without the K suffix is available if your circuit already has a check valve. Drain is the differential-pressure default, with automatic and manual drain options - a manual-drain version widens the regulator's lower limit to 0.05 MPa. Regulation range on this differential-drain set is 0.15-0.9 MPa (20-130 psi), read on the round MPa gauge; square gauges with MPa, psi or bar scale can be ordered. Thread is PT as standard, with G (BSPP) and NPT as options. Flow is published as curves, not a single rating - ask us to confirm sizing 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-C0 filter regulator on its own.
AirTAC publishes flow for the G series as characteristic curves rather than one rated number, so we do not state a single figure here. Give us your line pressure, downstream air demand and acceptable pressure drop, and we will confirm the sizing and the curve data from the datasheet on request.
The trailing K means a reverse (check) valve is fitted to the set. The identical unit without the K suffix (GFC300C08C1W) is offered when your circuit already includes its own check valve, so you can order the version that matches your piping design.
