The AirTAC GC30008F2 AirTAC F.R.L. Combination 1/4 in PT 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30008F2 is a three-piece F.R.L. combination that filters, regulates and lubricates compressed air in one assembled set: a separate filter, a separate regulator and a separate oil-mist lubricator. This size 300 unit is fitted with a PT1/4 (1/4 in) port, a 40 um filter element and a differential-pressure drain on the filter bowl, so collected water is expelled automatically whenever the pressure differential across the element rises. The standard regulator adjusts from 0.15-0.9 MPa (20-130 psi) and carries an embedded square gauge scaled in psi, while the lubricator meters oil mist downstream to keep air tools and cylinders running. The polycarbonate bowls suit the -5 to 70 C (non-freezing) operating range, and a mounting bracket is included.
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, G or NPT thread options, automatic or manual drain choices, a 5 um filter element option, gauge scale choices and reverse/check valve options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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 0.15 - 0.9 MPa (20 - 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.

Feeds impact wrenches, air ratchets and nutrunners at assembly stations with water- and particulate-filtered air held at a set pressure, plus a continuous oil mist that extends tool life across shifts.
Supplies the pneumatic cylinders and grippers on a packaging conveyor with clean, regulated and lubricated air, so seal heads and pick-and-place motions hold consistent speed through the shift.
Prepares the shop-air supply feeding a machining centre's pneumatic clamps, tool-changer cylinders and air-blast nozzles, keeping moisture and swarf out of the valves while the regulator holds the clamp pressure steady.
Start with the size and port: 200, 300, 400 and 600 step up in port size and flow capacity, so match the step to the air consumption of the tools and cylinders downstream - here that is size 300 with a PT1/4 (1/4 in) port. Then set the drain: differential-pressure (this unit) drains the filter bowl automatically on pressure rise, while automatic drains continuously and manual drains need an operator. Filter grade is 40 um standard or 5 um with the W suffix if finer filtration is needed. Gauge scale is selectable (MPa, psi or bar) and this configuration carries the embedded square gauge in psi. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow as curves, not as a single rated figure, so we cannot quote a rated flow number for this unit. Send us your application details and we will confirm the sizing against the datasheet curves 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.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not state a rated flow, Cv or SCFM number. Tell us your application and downstream air consumption and we will confirm the sizing against the datasheet curves on request before you order.
This GC30008F2 carries the differential-pressure drain as its default: water collected in the filter bowl is expelled automatically when the pressure drop across the 40 um element rises to a set level. The automatic drain option (code A) discharges condensate continuously regardless of differential, and the manual drain option (code M) discharges only when an operator opens it, which suits lines that are checked daily. All three are catalogue drain choices on the GC filter stage.
