The AirTAC B52-GFC Copper-Free Air Source Treatment Component B52-GFC30008MLC1W 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 PT1/4" ports, a 5 µm element, a manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GFC series is a two-piece air-treatment set: a filter regulator plus a separate lubricator, so the air is filtered, regulated and then oil-mist lubricated in one supply line. This GFC30008MLC1W is the 300 size with 1/4 in PT ports, a manual drain on the filter bowl, a 5 um (W) filter element for finer particulate removal, the low-pressure regulator type, and an external round pressure gauge reading in MPa.
This is a genuine AirTAC part. The G series is offered in 200, 300, 400 and 600 sizes with a choice of PT, G(BSPP) or NPT threads, drain types, 40 um standard or 5 um filter grades, and square or round gauges. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing 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.
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". 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. |
| (blank) | No reverse-flow valve (the default). |
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: GFR300-08 filter regulator and GL300-08 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.

Feeding filtered, regulated and lubricated air to the clamping and punching cylinders of a small pneumatic press, with the 5 um element guarding directional valves against fine contamination.
Supplying oil-mist lubricated air to the pusher and diverting cylinders along a packaging conveyor, where the low-pressure regulator type keeps actuation pressure gentle on lightweight product.
Preparing the air feed to a spray-gun manifold, combining fine 5 um filtration, stable low-pressure regulation and in-line lubrication for the gun trigger valves.
The 300 size with 1/4 in PT ports is the entry point of the mid range; step up to 400 or 600 if your line needs larger ports and more flow, or down to 200 for compact circuits. The manual drain here suits installations where an operator bleeds the bowl as part of routine checks; choose the automatic drain variant for unattended duty. The 5 um element protects finer components than the 40 um standard, at the cost of more frequent element checks. The round MPa gauge is the external option; a square embedded gauge is also available in MPa, psi or bar scales.
Flow for this set is published as curves, not a single rated figure, so ask us to confirm sizing against your flow demand before ordering. PT is the standard thread; G(BSPP) and NPT are catalogue options to specify at order time.
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 GFR300-08 filter regulator on its own.
AirTAC publishes flow for the GFC300 as performance curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your flow demand and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code selects a manual drain, so the filter bowl is bled by hand during scheduled checks instead of automatically. The W selects the 5 um element instead of the 40 um standard, for finer protection of downstream components. The F.R.L. also uses the low-pressure regulator type and carries a round external gauge reading in MPa.
