The AirTAC GC30015MC2GK AirTAC F.R.L. Combo, G 1/2 in, Manual Drain 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 PT1/2" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30015MC2GK is an AirTAC GC-series three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is size 300 with a G 1/2 in (BSPP) port, a 40 um standard filter element, a manual drain on the filter bowl, and a round pressure gauge reading in psi. The reverse/check valve (code K) is fitted, and a mounting bracket is included. The polycarbonate bowls suit this size class, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC range spans sizes 200, 300, 400 and 600, with port options, drain types (differential-pressure, automatic or manual), a 5 um filter element option (code W), gauge scale choices (MPa, psi or bar), and G or NPT thread variants available to order. Flow is published as curves rather than a single rated figure, so we confirm datasheet and sizing figures 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 0.05 - 0.9 MPa (7 - 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.

|---|---|
| 15 | Port size PT1/2". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |

| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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: GF300-15 filter, GR300-15 regulator and GL300-15 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.

Conditions the compressed air feeding a CNC machining centre's pneumatic clamps and tool-change cylinders: water and swarf-laden particulate are stripped out, line pressure is set and held at the value the machine builder specifies, and the lubricator meters oil mist to keep air cylinders sealing and moving smoothly.
Feeds the air cylinders on a carton-forming and case-sealing conveyor line. The filter removes condensate and pipe scale before it reaches the valve island, the regulator holds a stable setting so case-clamp cylinders act consistently, and the lubricator keeps the actuators serviceable over long production runs.
Installed at the drop leg of a manual assembly bench where air tools and small presses are connected. Clean, regulated, lubricated air at the point of use protects the tools and the workpiece, while the manual drain lets the operator bleed accumulated condensate at the start of each shift.
Size 300 with a G 1/2 in port sits in the middle of the GC range; step up to 400 or 600 for larger ports and higher flow capacity, or down to 200 for smaller lines. This unit has a manual drain, which suits installations where an operator can bleed the bowl on a routine; choose the automatic or differential-pressure drain option if the bowl cannot be checked regularly. The 40 um element is the standard grade for general plant air; specify the 5 um (W) option where finer particulate removal is needed. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are alternatives. G (BSPP) thread is specified here; PT is the standard thread and NPT is also a catalogue option. A mounting bracket is included.
Flow for this series is published as curves, not a single rated number, so please ask us to confirm sizing against your application before ordering.
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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so there is no one rated flow number we can quote for this 1/2 in unit. Tell us your application and required flow, and we will confirm the sizing from the datasheet on request before you order.
The M in the code specifies a manual drain on the filter bowl: condensate collects in the bowl until someone opens the drain. This GC30015MC2GK is therefore best placed where an operator passes regularly. If the installation is unattended, ask us about the same unit with the automatic (A) or differential-pressure (blank) drain option instead.
