The AirTAC B52-GFC Copper-Free Air Source Treatment Component B52-GFC30010MLC1WK 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).
GFC30010MLC1WK is an AirTAC G-series two-unit air-treatment set: a filter regulator plus a lubricator, with a reverse/check valve (K) fitted. It removes water and particulate from compressed air, regulates downstream pressure and adds oil mist for the cylinders and air tools that follow it. This 300-size set has PT3/8 ports (PT is the standard thread; G and NPT are catalogue options), a manual drain on the bowl, the finer 5 um W filter element instead of the 40 um standard, the L low-pressure type variant, and an external round pressure gauge reading in MPa. Max working pressure is 1.0 MPa (145 psi); with manual drain the regulator adjustment range is 0.05-0.9 MPa (7-130 psi). Operating temperature is -5 to 70 C, non-freezing. At size 300 the bowls on both the filter regulator and the lubricator are PC (polycarbonate).
This is a genuine AirTAC part. The GFC two-unit family is also available in 200, 400 and 600 sizes, with a choice of ports, differential-pressure or automatic drain, 40 um or 5 um filtration, square or round gauges in MPa, psi or bar scales, with or without the reverse/check valve. Because rated flow is published as curves rather than a single figure, ask us to confirm flow and datasheet figures 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

The decodable choices here: size and port (300 with PT3/8; move to 200, 400 or 600 to match air demand, larger sizes giving larger ports and more flow); drain type (manual M here, with differential-pressure as the default and automatic A as the alternative); filter grade (5 um W fitted, finer than the 40 um standard); gauge (round, MPa scale C1; square embedded gauges and psi or bar scales are options); thread (PT standard, G or NPT on order); and the K suffix, which adds the reverse/check valve that the plain GFC30010MLC1W omits. Flow is published as curves, not a single rating, so ask us to confirm sizing from the datasheet 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 GFR300-10 filter regulator on its own.
Flow for the GFC series is published as curves, not as one rated number, so we do not state a figure on the page. Share your required flow and operating pressure and we will confirm the right size from the datasheet on request.
Manual drain (M) means the bowl is emptied by hand, which suits stations that are checked regularly; differential-pressure drain is the default and automatic (A) drain suits unattended installations. The K suffix adds a reverse/check valve to the set, which the equivalent code without K does not carry.
