The AirTAC AirTAC GC300-08 FRL Unit (GC30008MLC1W) 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).
GC30008MLC1W is an AirTAC G-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator built into one 300-size set. The W in the code selects the finer 5 um filter element instead of the standard 40 um. This 1/4 in PT-threaded unit is the low-pressure (L) type, has a manual drain on the filter bowl, and is fitted with an external round pressure gauge scaled in MPa. On this 300 size the bowl is polycarbonate (PC). Medium is compressed air, with a maximum working pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G series runs from size 200 through 600 with a choice of ports, drain types, filter grades, gauge styles and scales, and G (BSPP) or NPT thread options. The standard manual-drain regulator adjusts 0.05-0.9 MPa (7-130 psi); as the low-pressure (L) variant this set is intended for lower setting pressures, so confirm the exact range with us. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures 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.

Feeds the pneumatic grippers and lifters on laboratory automation benches, where the 5 um element helps keep fine particles out of sensitive pilot valves.
Prepares air for the pick-and-place cylinders in a small assembly cell, with the low-pressure regulator set to gentle operating pressures and the gauge read in MPa.
Supplies the control-air circuit of an offset printing press, combining fine 5 um filtration, pressure regulation and oil mist for the machine's directional valves.
Size and port come first: the 300 series on a 1/4 in PT port suits lighter-duty circuits, and 200, 400 or 600 sizes step capacity down or up - match the set to the air demand downstream. This is the low-pressure (L) type for lower setting pressures; confirm the adjustment range with us before ordering. The W code gives you the 5 um element instead of the standard 40 um grade - worth it when valves and cylinders downstream are sensitive to finer particles, at the cost of more frequent element checks. The drain is manual (M), so plan to empty the bowl by hand, or choose differential-pressure or automatic (A) draining instead. Gauge is this external round type (C) in MPa scale; square (F) and psi or bar scales are options, as are G (BSPP) and NPT threads. Flow is published as curves, not a single rating, so let us confirm sizing against your application 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 GR300-08 regulator with a GF300-08 filter on that branch.
Flow for the G series is published as performance curves rather than a single rated figure, so we do not state one number here. Share your working pressure and required air consumption and we will confirm the flow from the datasheet before you order.
The standard GC filter element is 40 um. The W code upgrades it to 5 um, which suits circuits with fine pilot valves or sensitive actuators. If you only need bulk water and particle removal ahead of a regulator, the standard 40 um grade is usually the simpler choice - we can help you decide against your application.
