The AirTAC GC30010ALF2K AirTAC F.R.L. 3/8 in PT Air Combination Unit 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30010ALF2K is a three-piece F.R.L. air-combination unit: a separate filter, a pressure regulator and an oil-mist lubricator assembled in one GC set. This configuration is the size 300 body with a 3/8 in PT port. The filter section carries the standard 40 um element and an automatic drain, so condensate is ejected from the PC bowl without an operator having to open the drain. The regulator is the low-pressure type and is fitted with an embedded square gauge scaled in psi; the set also carries a reverse/check valve and includes a mounting bracket.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge scale, thread (PT standard, G and NPT to order) and reverse valve. Flow is published in the catalogue as curves rather than a single rated figure, so we confirm the datasheet and flow figures 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.

On a stamping or assembly press fed by shop air, this GC set filters water and swarf from the supply, holds a stable low-pressure setting at the clamping cylinders via the psi gauge, and mists oil to keep cylinder seals and valves lubricated through long production runs.
Packaging lines run air cylinders, vacuum generators and glue heads continuously; the 3/8 in PT GC set cleans and regulates the air at the machine inlet, the automatic drain keeps condensate out of the valves on unattended shifts, and the lubricator protects the actuator population downstream.
At a robotic assembly cell with air tools, grippers and nutrunners, this unit provides filtered, regulated and lubricated air at the cell drop. The check valve holds the downstream circuit against supply dips, and the 40 um element protects the tooling between plant dryer stages.
Start with the port step: size 300 with a 3/8 in PT port suits lines plumbed at 3/8 in, while larger sizes 400 and 600 move up to 3/4 in and 1 in for higher-demand circuits - match the size to the flow your line needs and we will confirm the curve figures before you order. For the drain, automatic (this unit) suits unattended duty, manual suits periodically serviced stations, and the differential-pressure default drains on a set pressure drop. Filter grade is 40 um standard; specify W for 5 um where finer particulate removal is needed. The gauge is embedded and square on this unit, scaled in psi, with MPa or bar scales and an external round gauge available as options. Thread is PT as standard with G (BSPP) and NPT as order options, and the bracket is included. The regulator here is the low-pressure type - confirm its adjustment range against your set pressure with us 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, not as a single rated number, so we do not quote a figure that is not in the datasheet. Tell us your working pressure and the air demand of the equipment downstream, and we will confirm the correct size and the flow-curve figures against your application before you order.
This set is coded A for automatic drain: condensate collected in the filter bowl is ejected without operator intervention, which suits unattended or hard-to-reach installations. The GC family also offers manual drain (code M) for stations serviced on a schedule, and the differential-pressure drain as the default, which discharges when the pressure drop across the element reaches its set point. The bowl on this size 300 unit is PC (polycarbonate).
