The AirTAC GC300C10AF2K AirTAC F.R.L. Combination, PT3/8 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC300C10AF2K 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 configuration is sized 300 with a PT3/8 port, carries the standard 40 um filter grade, and uses an automatic drain on the filter bowl so collected water is expelled without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), an embedded square gauge with a psi scale is fitted, and a reverse/check valve is included to hold downstream pressure. The mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, and choices of drain type, filter grade (40 um standard, 5 um with code W), gauge scale (MPa, psi or bar) and thread (PT standard, with G and NPT available as order options). Flow is published as curves rather than a single rated figure, so ask us to confirm the 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. 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-C1 filter, GR300-C1 regulator and GL300-C1 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 spray-booth air drops where filtered, regulated and lubricated air keeps paint lines running; the automatic drain handles condensate between shifts without operator attention.
Supplies the machine tool's pneumatic circuit - clamps, tool changers and air bearings - with clean, regulated, oil-misted air at a set pressure held by the fitted check valve.
Conditions the air feeding conveyor diverters and carton-sealing cylinders, so seals and cylinders get particulate-free, pressure-stabilised, lubricated air at PT3/8.
Step up or down through the GC sizes (200/300/400/600) to match the port and the flow your line needs - this 300 unit sits at PT3/8. Drain choice matters: automatic drain suits unattended duty, manual drain suits supervised points, and the differential-pressure default drains only when the pressure drop calls for it. Filter grade is 40 um standard; specify code W for 5 um where finer particulate removal is required. The fitted square gauge reads in psi; MPa and bar scales are alternatives, and an external round gauge is optional. Thread is PT as standard, with G (BSPP) and NPT as order options, and the bracket is included.
Because catalogue flow is published as curves rather than one rated number, send us your application details and we will confirm the sizing against the datasheet 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-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for this family as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and sizing against the datasheet before you order.
The A in the code selects the automatic drain on the filter bowl: collected condensate is expelled without manual attention. The alternatives are manual drain (you bleed the bowl yourself) and the differential-pressure default (it drains only when the pressure drop calls for it). Note that with an automatic drain the regulator adjustment range is 0.15-0.9 MPa (20-130 psi).
