The AirTAC GC300C10LF2 AirTAC F.R.L. Combination PT3/8 Low-Pressure 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 GC300C10LF2 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one working set. This 300-size unit is ported PT3/8 (3/8 in, PT thread standard; G and NPT are order options). The filter element is the standard 40 um grade with a differential-pressure drain that bleeds collected water automatically when the pressure differential rises, so there is no drain fitting to operate in normal service. The regulator is the low-pressure type, suited to applications whose setpoint sits in the lower part of the working range, and it carries an embedded square gauge reading in psi; an external round gauge is optional. No reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC combination is published in 200, 300, 400 and 600 sizes, with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, a 5 um (code W) filter element option, gauge scale choices, and G or NPT threads to order. Rated flow for this series is published as curves rather than a single figure, so ask us to confirm flow and datasheet figures against 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-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 filtered, regulated and lubricated air to impact drivers and air screwdrivers on a trim line, where the low-pressure regulator type suits lower setpoints and the lubricator keeps tool motors running smoothly.
Conditions shop air ahead of spray guns: the 40 um element removes water and particulate that would spoil finishes, the regulator holds a steady low atomizing pressure, and the lubricator is bypassed or set per the gun maker's guidance.
Placed upstream of the cylinders and air actuators on a case-sealing conveyor, giving the machine clean, pressure-stable and lubricated air so cylinder seals and valve spools last through continuous shifts.
Size the GC set by port and expected air demand: the 300 size here is PT3/8, one step up from the 200 size, and the 400 and 600 sizes carry larger ports for higher demand. Because flow is published as curves rather than a single rated number, ask us to confirm sizing against your application before ordering. On this configuration the drain is differential-pressure (automatic in service); automatic and manual drains are available if your maintenance routine prefers them. The filter element is the standard 40 um grade; specify the W option for 5 um filtration. The regulator on this unit is the low-pressure type - if your setpoint sits higher in the working range, ask us about the standard type and the exact adjustment range for each. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket is included.
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 the GC series as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure, setpoint and expected air demand and we will confirm the flow and full datasheet figures for this exact model on request before you order.
The L in the code marks the low-pressure regulator type, intended for applications whose working setpoint sits in the lower part of the pressure range, in contrast to the standard type. The exact adjustment range for the low-pressure type is not published as a single figure, so ask us to confirm it against your setpoint on request.
