The AirTAC AirTAC GC300C10AF2GK 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC300C10AF2GK is a three-piece F.R.L. air-treatment combination: a filter, a pressure regulator and an oil-mist lubricator mounted together, so one assembly cleans the compressed air, holds the working pressure steady and carries oil mist downstream to pneumatic tools and actuators. This configuration is built around G3/8 ports, with the filter section draining automatically, a 40 um standard filter element, an embedded square gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included.
This is a genuine AirTAC part in the GC series, which spans sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades (40 um standard, 5 um optional), gauge scales and thread options. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet 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. 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 cleaned, regulated and lubricated air to the tool-clamp cylinders, chip-clearing jets and pallet-clamping circuits of a CNC machining centre, with the check valve holding the circuit if supply pressure dips.
Serves the pneumatic cylinders on a carton-forming and case-sealing conveyor line, where the automatic drain copes with condensate on a line that runs unattended across shifts.
A point-of-use F.R.L. for assembly-station air drops in a general manufacturing plant, protecting impact drivers and air ratchets with filtration, stable regulated pressure and oil-mist lubrication.
Start with the port size: this unit steps up to 3/8 in, so match it against the air consumption of the machines on the line and step to size 400 or 600 if the demand is higher, or down to 200 if it is a compact drop. The automatic drain on the filter bowl suits points where nobody walks past regularly; choose manual or differential-pressure drain codes if your maintenance routine differs. The 40 um element is the standard grade for general plant air - specify the W code for the 5 um element only where finer pre-filtration is genuinely needed downstream. The square gauge here reads in psi; MPa and bar scales are available, and an external round gauge is an option. Thread is G (BSPP) as coded; PT is the standard and NPT is an order option.
Because AirTAC publishes flow as curves rather than one rated figure, we do not quote a flow number here - send us your application details and we will confirm 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 series as curves, not as a single rated number, so we do not state a flow figure. Send us your line pressure and the air consumption of the equipment you intend to feed, and we will confirm the sizing against the datasheet on request.
The A in the code means the filter bowl has an automatic drain, so collected condensate is expelled without anyone opening the bowl - useful on lines that run unattended. Manual and differential-pressure drain versions are available as separate codes in the same GC300 size if your maintenance routine suits them better.
