The AirTAC GC30008G AirTAC F.R.L. Combination, G1/4, 5 um, Manual Drain 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 GC30008G is a three-piece AirTAC GC series F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This configuration is built for G1/4 (1/4 in) ports with G thread, carries a 5 um filter element for finer particulate and water removal than the standard 40 um grade, and uses a manual drain on the filter bowl, so an operator drains collected condensate by hand as part of routine checks. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and this unit is fitted with an external round gauge scaled in psi; the embedded square gauge is the standard option and MPa or bar scales can be ordered. The polycarbonate bowl suits the 300 size, maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C in non-freezing conditions.
This is a genuine AirTAC part. The GC series is available in 200, 300, 400 and 600 sizes covering ports from 1/8 in to 1 in, with choices of drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT as order options) and a mounting bracket. Flow is published in the catalogue as curves rather than a single rated figure, 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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.

A filtered, regulated and lubricated air drop feeding the tool-changer and clamping cylinders on a machining centre, where the 5 um element protects fine spool valves and the lubricator keeps actuation air oil-misted.
Air preparation for the pick-and-place and sealing cylinders on a packaging conveyor, with the regulator holding a steady set pressure for consistent cycle behaviour and the manual-drain filter emptied during shift checks.
A bench-side air set for manual assembly stations running air tools and small actuators, giving one point where the operator reads line pressure on the psi gauge, drains the bowl and maintains the oil-mist feed.
Start with the size and port: the 300 size with G1/4 ports is the right step when your line runs on 1/4 in piping and your air demand sits in that size band - step up to 400 or 600 for larger flows, down to 200 for compact circuits. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Then set the options this code carries: manual drain (operator-drained bowl, simplest and lowest cost, versus automatic or differential-pressure drain for unattended operation), the 5 um W-grade element where downstream valves and cylinders need finer filtration than the standard 40 um, and the round external gauge with psi scale (square embedded gauge is standard; MPa and bar scales are available). G thread is an order option alongside the PT standard and NPT, and the mounting bracket is included. Confirm the exact thread and gauge scale you want when 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 in the catalogue, not as a single rated number, so we do not quote a figure that is not in the datasheet. Tell us your line pressure, port size and expected air consumption, and we will confirm the flow curve and correct sizing from the datasheet on request before you order.
The M in the code sets a manual drain on the filter bowl: an operator opens the drain to release collected water and contaminants, typically as part of a scheduled check. If you cannot guarantee that routine, the GC series also offers automatic and differential-pressure drain options on the same sizes - ask us to quote the alternative code.
