The AirTAC GC300C15AF2GK AirTAC F.R.L. Combination, G1/2 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 GC300C15AF2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator set up as one conditioning station for compressed air. This size 300 unit is threaded G1/2 (G/BSPP), carries the standard 40 um filter element with an automatic drain on the filter bowl, and regulates outlet pressure across 0.15-0.9 MPa (20-130 psi) before feeding oil mist downstream. A square gauge scaled in psi is fitted, a reverse/check valve is installed to hold downstream pressure if supply fails, and a mounting bracket is included. The polycarbonate bowls are rated for a maximum inlet pressure of 1.0 MPa (145 psi) and the unit operates from -5 to 70 C in non-freezing conditions.
This is a genuine AirTAC part. The GC line spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include manual or differential-pressure drains, a finer 5 um element (code W), gauge scales in MPa, psi or bar, and NPT or G threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your line 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 spray guns and air-assisted applicators on a paint line, where water and particulate must be stripped out, pressure held steady at the gun, and a fine oil mist carried to keep air motors running smoothly through a shift.
Supplies the cylinders and grippers on a carton former or case sealer, giving the line a single point where air is filtered, regulated to the actuator circuit's set pressure, and lubricated for long cylinder life.
Conditions the air feeding pneumatic clamps and tool-change actuators on a machining centre, holding a stable regulated pressure so workholding behaves consistently part after part, with the check valve helping hold the circuit if supply is interrupted.
Step through the real choices: first size the unit by port and expected flow - size 300 with a 1/2 inch port sits mid-range in the GC line, and larger sizes carry larger ports and more flow. Choose the drain: this configuration has an automatic drain on the filter bowl, which suits unattended installations; manual and differential-pressure drains are available if you prefer operator-controlled or pressure-differential purging. The standard element is 40 um; specify code W if the application needs 5 um filtration. The fitted square gauge reads in psi, and MPa or bar scales can be ordered instead. This unit is threaded G (BSPP); PT is the standard thread and NPT or G are catalogue options to order. A mounting bracket is included. Because flow is published as curves rather than a single rating, 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-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 working pressure and the flow your line needs, and we will confirm the sizing from the datasheet curves on request before you order.
This GC configuration combines filtration, regulation and lubrication as three separate units, so each stage can be serviced on its own; a two-unit GFC set covers only filter-regulator plus lubricator. The automatic drain on the filter bowl purges collected condensate by itself, which suits installations that are not checked daily - manual and differential-pressure drains are available as alternatives.
