The AirTAC GC300-10 AirTAC F.R.L. Combination, G3/8, 5 um Filter is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT3/8" ports, a 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC300-10 is a three-piece AirTAC F.R.L. combination: a filter, a pressure regulator and an oil-mist lubricator assembled as one air-preparation set for a compressed-air line. This configuration is built for a G3/8 (BSPP) port on the GC300 size, with 5 um filtration (the W grade, finer than the 40 um standard), a manual drain on the filter bowl, a low-pressure-type regulator fitted with an external round gauge scaled in psi, a reverse/check valve, and a mounting bracket included. The polycarbonate bowls are for non-freezing compressed air from -5 to 70 C, with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and in thread options PT (standard), G and NPT; drain type, filter grade, gauge and scale are chosen per code. Rated flow for this combination is published as curves rather than a single figure, so ask us and we will confirm the 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 combination has no separate bracket code — the three 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.
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 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. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) 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. Constituent units, orderable separately as spares: GF300-10 filter, GR300-10 regulator and GL300-10 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Feeds filtered, regulated and lubricated air to a machine tool's pneumatic clamps, tool changer and chip-ejection cylinders: the 5 um grade protects fine control valves while the lubricator mists the actuator seals.
Conditions air for carton-sealer and case-erector cylinders on a packaging line, with the low-pressure regulator suiting circuits run below standard line pressure and the manual drain letting operators bleed off collected water at shift start.
Installed as a point-of-use set on an assembly-plant air drop serving air tools and impact drivers, giving the station its own filtration, regulation with a local psi gauge, and oil-mist lubrication in one unit.
Step up or down through the GC sizes (200/300/400/600) to match the port and the flow your line needs; this code is the 300 size with a G3/8 port. Choose the drain: differential-pressure (default), automatic (A) or manual (M, as here). Choose the filter grade: 40 um standard or 5 um (W, as here) where finer particulate removal matters. Pick the gauge style and scale (embedded square standard, external round optional; MPa, psi or bar), the thread (PT standard, G or NPT to order), and whether a bracket is fitted. Because flow is published as curves rather than a single rating, send us your air demand and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR300-10 regulator with a GF300-10 filter on that branch.
Flow for this combination is published as performance curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the datasheet flow figures for this 3/8 in, 5 um, low-pressure configuration on request.
The L marks the low-pressure-type regulator, intended for circuits controlled below the standard setting range; AirTAC does not publish the exact range for this variant, so we confirm it on request. The rest of the code decodes as: manual drain (M), round gauge scaled in psi (C2), 5 um filter grade (W), G thread, and a reverse/check valve (K).
