The AirTAC GC300C15MLF2K AirTAC F.R.L. Combination 1/2 in PT 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 GC300C15MLF2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one filtered-air supply point. This configuration is built around a 1/2 in PT port, a 40 um filter element with a manual drain, a low-pressure type regulator fitted with an embedded square gauge scaled in psi, and a reverse/check valve. The manual drain means an operator opens the filter bowl drain at intervals to release collected water, which suits lines that are checked as part of a routine walk-round. The lubricator meters a fine oil mist into the downstream air for pneumatic tools and cylinders that need lubrication.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with a choice of port sizes, PT, G or NPT thread, differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) filter element, gauge scale options and a reverse/check valve. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for 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.

A filtered, regulated and lubricated air point feeding paint spray guns and air-assisted equipment on a body-shop line, where clean, moisture-free and correctly pressurised air protects finish quality.
Conditioning the air feeding pick-and-place and carton-forming cylinders on a packaging conveyor, with the lubricator keeping seals and moving parts serviced by the plant air supply.
A wall-mounted F.R.L. point at a machine-shop tool station supplying impact wrenches, air chisels and clamping fixtures that rely on lubricated, regulated air at a stable low setting.
Start with the port and size step: this unit is a size 300 with a 1/2 in PT port, and the larger the size (200/300/400/600), the larger the port and the greater the flow capacity - match the step to the air demand of the machines downstream. Choose the drain to suit attendance: manual (as here) needs periodic draining, automatic drains itself, and the differential-pressure default drains on a pressure drop. Choose the filter grade: 40 um is standard for general plant air; the 5 um (W) element suits finer applications. Gauge scale is selectable (MPa, psi or bar) - this unit carries a square gauge in psi. Thread is PT as standard with G (BSPP) and NPT as order options, and a mounting bracket is included. Note this is the low-pressure type regulator, so confirm the setting range with us. Because flow is published as curves rather than a single rated figure, 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 performance curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and downstream air demand and we will confirm the correct size and the flow curve data from the datasheet on request.
The M in the code means the filter bowl has a manual drain: an operator opens it periodically to release collected water, unlike the automatic or differential-pressure drain options. The L means this is the low-pressure type regulator; its exact setting range is not published in the material we hold, so confirm it with us and we will check the datasheet.
