The AirTAC AirTAC GC300-08 FRL Unit (GC30008MLF1) 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).
GC30008MLF1 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. This 1/4 in PT-threaded unit is the low-pressure (L) type, has a manual drain on the filter bowl, keeps the standard 40 um filter element, and is fitted with a square 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, 40 um or 5 um filter elements, 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.

Prepares air for the pneumatic cylinders and controls on warehouse dock levellers, with the manual-drain bowl checked during scheduled dock maintenance.
Supplies filtered, regulated and lubricated air to the secondary pneumatic functions on an injection moulding machine, with the square gauge read in MPa.
Feeds the low-pressure pneumatic circuits of a workshop test rig, where the regulator is set well below main-line pressure and the square gauge shows the setting at a glance.
Begin with size and port: the 300 series on a 1/4 in PT port fits lighter-duty circuits, and 200, 400 or 600 sizes step capacity down or up - size the set to the air demand of what it feeds. This is the low-pressure (L) type for lower setting pressures; confirm the adjustment range with us before ordering. The drain is manual (M), so the filter bowl is emptied by hand - choose differential-pressure or automatic (A) draining if manual access is difficult. Filtration stays at the standard 40 um grade here; add W in the code for the 5 um element if finer pre-filtration is needed. This configuration carries the square gauge (F) in MPa scale; the external round gauge (C) and psi or bar scales are alternatives, and the thread can be ordered as G (BSPP) or NPT instead of PT. 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 this series is published as performance curves rather than a single rated figure, so we do not quote one number here. Tell us your application's working pressure and air consumption and we will confirm the flow from the datasheet before you order.
Both are MPa-scale gauges; F selects the square gauge type fitted here, while C selects the external round gauge. Scale 2 gives psi and scale 3 gives bar if you prefer a different unit - just order the code with the scale digit you need.
