The AirTAC B52-GFC Copper-Free Air Source Treatment Component B52-GFC300C15MC1WK 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).
GFC300C15MC1WK is a two-piece AirTAC G-series air-treatment set: a filter-regulator paired with a lubricator, so the compressed air is filtered, regulated and then oil-mist lubricated in one group. This configuration has 1/2 in PT ports, a manual drain on the filter bowl, a 5 um filter element, a round pressure gauge scaled in MPa, and a reverse (check) valve fitted to hold the downstream circuit if supply pressure drops. Both bowls on this 300 size are polycarbonate.
This is a genuine AirTAC part. The GFC two-unit sets are offered in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and this model runs at up to 1.0 MPa (145 psi) inlet with a 0.05-0.9 MPa (7-130 psi) regulating range. Flow for the set is published as performance curves rather than a single rating, so we confirm the 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 0.15 - 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-C1 filter regulator and GL300-C1 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.

Filtering, regulating and lubricating the shop air that feeds the clamping cylinders and tool changer on a CNC machining center, with the check valve holding the set pressure if the main line dips.
Keeping the pneumatic cylinders on a carton-forming and sealing line supplied with clean, oiled air held at one stable setting through the whole shift.
Feeding impact wrenches and nutrunners at an assembly station with filtered, oil-mist lubricated air, so the tools receive consistent lubrication at the pressure the station is set to.
In the G-series you step from size 200 to 600 as port size and required flow grow; the 300 size with 1/2 in PT threads is aimed at medium machine supply lines. Drain type is a real choice: this code carries a manual drain, whose regulator allows a 0.05-0.9 MPa (7-130 psi) setting, while automatic-drain and differential-pressure variants exist in the series. The 5 um element gives finer protection than the standard 40 um. The gauge here is the round external type in MPa; square-gauge versions and psi or bar scales are also catalogue options. Thread is PT as standard, with G (BSPP) and NPT orderable, and bracket mounting is optional. Because flow is published as curves, not a single 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 GFR300-C1 filter regulator on its own.
AirTAC publishes flow for the GFC series as performance curves rather than one rated figure, so we do not quote a single number here. Tell us your line pressure and demand and we will confirm the datasheet flow figures for this exact model on request.
The manual drain means accumulated moisture is released by opening the drain fitting, and the manual-drain regulator allows a 0.05-0.9 MPa (7-130 psi) setting; automatic-drain variants are available in the series if you prefer. The K in the code means a reverse (check) valve is fitted, which prevents backflow through the unit.
