The AirTAC GC30008MLC2W AirTAC F.R.L. Unit, PT1/4, 5 um, psi Gauge 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 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC300 is AirTAC's three-piece F.R.L. combination: a filter, a pressure regulator and an oil-mist lubricator assembled as one air-treatment set. This unit is built for a PT1/4 (1/4 in) port, carries a 5 um filter element (code W), and uses a manual drain on the filter bowl, which is polycarbonate at this size. The regulator is the low-pressure type, and a round pressure gauge scaled in psi is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC series is published in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, a choice of 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, gauge scale options, and G (BSPP) or NPT threads as order options. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing for your application.

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.

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.

Feeding clean, regulated and lubricated air to the cylinders and clamps of a bench or assembly press, with the 5 um element protecting valve surfaces and the manual drain cleared during shift checks.
Supplying treated air to diverters, pushers and sealing heads on a packaging conveyor, where the low-pressure regulator holds a lower working pressure and the lubricator keeps actuation air oil-misted.
Conditioning air for spray guns and finishing lines that run at reduced pressure: the 5 um filtration removes water and particulate ahead of the gun, and the psi-scaled round gauge gives a direct pressure readout at the booth.
Start from the port and size: the 300 size with a PT1/4 port suits lines piped at 1/4 in, and the larger 400 and 600 sizes step up in port and flow capacity - match the size to the air demand of the machine. Choose the drain: this unit has a manual drain, which needs periodic draining by hand; automatic or differential-pressure drains are available if you prefer unattended operation. Filtration is 5 um here (code W); the standard element is 40 um if finer filtration is not required. The fitted gauge is round and scaled in psi; the embedded square gauge and MPa or bar scales are the other catalogue options. Thread is PT as standard, with G (BSPP) and NPT available to order, and a mounting bracket is included. One honest note: the low-pressure regulator's adjustment range is not published as a single figure, and flow is published as curves, not a rated number - ask us to confirm both 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 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 rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow curve and datasheet figures for this PT1/4, 5 um, manual-drain unit on request, so you can size it correctly before ordering.
The L in GC30008MLC2W marks the low-pressure regulator type, intended for circuits working at lower pressures than the standard variant. The exact adjustment range for this variant is not published as a single figure, so we confirm it on request. Everything else decodes normally: PT1/4 port, 5 um filtration, manual drain, round psi gauge, and mounting bracket included.
