The AirTAC GC300C10MC2GK AirTAC F.R.L. Combination, 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 GC300C10MC2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package for compressed-air lines. This configuration is built on the 300 size with a G3/8 (BSPP) port, a 40 um filter element for standard water and particulate removal, a manual drain for emptying the filter bowl, and a standard regulator covering 0.05-0.9 MPa (7-130 psi). A round gauge scaled in psi is fitted so line pressure can be read and set directly, and a reverse/check valve is included to hold downstream settings if the upstream supply is interrupted.
This is a genuine AirTAC part. The GC family is offered in 200, 300, 400 and 600 sizes with a choice of PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, and gauge style and scale options. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, 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 filtered, regulated and lubricated air to pneumatic impact wrenches, nutrunners and clamping cylinders at a vehicle assembly station, with the psi gauge letting technicians set tool pressure at the point of use.
Supplies clean, lubricated air to the pneumatic pushers and stopper cylinders that index bottles along a packaging conveyor, with the manual-drain filter bowl emptied during scheduled line cleaning.
Conditions shop air for tire changers, air ratchets and blow guns in a commercial vehicle service bay, where the regulator holds a steady working pressure and the lubricator keeps air tools running smoothly through a full shift.
Start with the size and port: the 300 series with a G3/8 connection sits in the middle of the GC range (200/300/400/600), so step up or down according to the air demand of the tools and actuators downstream. Choose the drain to match site practice: this unit has a manual drain, which suits attended installations where an operator can bleed the bowl on a routine; automatic or differential-pressure drains are available if the unit will be left unattended. The 40 um element is the standard grade; specify the 5 um (W) option only where finer particulate removal is genuinely needed. Gauge style (embedded square or external round) and scale (MPa, psi or bar) are selectable - this unit carries a round psi gauge. Thread is G here, with PT and NPT available as order options, and a mounting bracket is included. Because flow is published as curves rather than a single rated figure, send us your air demand 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 the GC series as performance curves rather than a single rated figure, so we do not quote one number here. Tell us your line pressure and the air demand of the equipment you are supplying, and we will confirm the flow figures from the datasheet for this exact model before you order.
The M in GC300C10MC2GK specifies a manual drain on the filter bowl: condensate is removed by opening the drain when servicing, which suits installations that are checked regularly. If the unit will sit unattended, the same GC300 body is available with an automatic drain (code A) or a differential-pressure drain (blank) instead - just ask for the alternative model code.
