The AirTAC GC30010LF2GK AirTAC F.R.L. Combination Unit, G3/8 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 PT3/8" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30010LF2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This size 300 unit carries a G3/8 port, a 40 um filter element with a differential-pressure drain on the filter bowl, a low-pressure type regulator fitted with an embedded square gauge scaled in psi, a reverse (check) valve, and a mounting bracket. The polycarbonate bowls suit the -5 to 70 C (non-freezing) operating range, and the maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600, with port options, thread variants (PT standard; G and NPT available to order), drain types, 5 um filtration (code W) and gauge scale choices. Flow figures are published as curves rather than a single rating, so we 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.

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: GF300-10 filter, GR300-10 regulator and GL300-10 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 filtered, regulated and lubricated air to carton-forming and sealing heads on a packaging line, where the low-pressure regulator holds steady settings and the check valve protects the set-up.
Supplying pneumatic screwdrivers and riveters at a bench assembly station, with 40 um filtration ahead of the tools and oil-mist lubrication keeping air motors running smoothly.
Preparing air for conveyor diverters, stoppers and lift cylinders, where the differential-pressure drain clears condensate on load and the psi gauge lets operators verify line settings at a glance.
Start with the port step: size 300 with a G3/8 port sits mid-range in the GC line, so step up to size 400/600 or down to 200 depending on the flow your line needs. Choose the drain for the filter bowl: differential-pressure (as fitted here) drains on load, automatic (A) suits unattended duty, and manual (M) gives operator control. The standard element is 40 um; specify 5 um (W) where finer cleaning is wanted. The low-pressure type regulator is the right pick when downstream settings stay at the lower end of the range, and the square psi gauge can be swapped for MPa or bar scale, or an external round gauge. Thread is G here; PT is standard and NPT is orderable. Because flow is published as curves rather than a single rating, ask us to confirm sizing 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so no single number is quoted. We will confirm the flow data from the datasheet and check it against your application on request before you order.
The L in the code marks the low-pressure type regulator, intended where downstream settings stay at the lower end of the range; the exact range is not published, so we confirm it on request. The blank drain code means a differential-pressure drain on the filter bowl, which discharges condensate in response to the pressure differential across the element.
