The AirTAC GC30008MLC2 AirTAC F.R.L. Combination, PT1/4, Low-Pressure 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 PT1/4" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30008MLC2 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one prepared air-treatment set. This configuration is the 300 size with a PT1/4 (1/4 in) port, PT thread, a 40 um standard filter element and a manual-drain filter bowl in polycarbonate. The regulator is the low-pressure type, so it is intended for circuits that run below standard regulated pressures; the exact adjustment range is not published, so confirm it against your set pressure before ordering. A round external gauge on the psi scale is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with matching port sizes, and with choices of thread (PT standard, G or NPT to order), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with code W), gauge style and scale, and low-pressure or standard regulator type. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. |
|---|---|
| 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. |

| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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: GF300-08 filter, GR300-08 regulator and GL300-08 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 workholding clamps and swing cylinders on a machining cell, with the low-pressure regulator suited to circuits running below standard line pressure.
Prepares the air supply for diverters, pushers and sealing cylinders on a packaging conveyor, where the lubricator keeps cylinder seals moving smoothly through long production shifts.
Installed at an assembly-bench air drop to clean, regulate and oil-mist the supply feeding air tools and small actuators, with the included bracket mounting the set at the point of use.
Start with the size and port: 300 is the mid size in the GC range, and the 08 position gives a 1/4 in port here - step up to 400 or 600 if your line's flow demand points to larger ports, since flow is published as curves rather than one rated figure. Choose the drain to match maintenance practice: this unit has a manual drain, which needs someone to open it periodically; automatic or differential-pressure drains are available if the unit sits where regular attention is impractical. The 40 um element is the standard grade; specify W for the 5 um option where finer filtration is required. The fitted round gauge reads in psi; MPa or bar scales and an embedded square gauge are the other catalogue choices. Thread is PT as standard - order G (BSPP) or NPT if your piping needs them - and the bracket is included. Before ordering, send us the application details and we will confirm sizing against the datasheet flow curves.
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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application - inlet pressure, set pressure and the equipment being fed - and we will confirm the flow figure from the datasheet on request before you order.
The M in the code GC30008MLC2 specifies a manual drain on the filter bowl, so condensate must be drained by opening the drain periodically. If the unit will be mounted where regular attention is not practical, the catalogue also offers automatic (A) and differential-pressure (blank) drains in the same size - ask us to quote the equivalent model.
