The AirTAC GC30015LC2 AirTAC F.R.L. Combination, PT1/2, 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 PT1/2" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015LC2 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one complete air-preparation set. This 300-size unit is specified with a PT1/2 port, the low-pressure regulator type, a 40 um standard filter element and differential-pressure drainage, so the filter bowl bleeds accumulated condensate as the pressure differential across the element builds. The polycarbonate bowls let you see water and oil levels at a glance, the fitted round gauge reads outlet pressure in psi, and the mounting bracket is included. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and with choices of drain type, filter grade (40 um standard, 5 um with code W), gauge style and scale, thread form and bracket. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm flow and datasheet figures for your application 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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: GF300-15 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.

Feeds filtered, regulated and lubricated air to spray booths and paint-line drops, where clean, moisture-controlled air protects finish quality and keeps air tools running smoothly through the shift.
Supplies the packaging line's cylinders and air actuators from one prepared-air point, conditioning the supply before it reaches sealers, labelers and carton-forming stations.
Conditions the air feeding clamps and press cylinders at an assembly cell, with the regulator holding a steady low-pressure setting and the lubricator misting the cylinders downstream.
Start with the port step: this 300-size unit carries PT1/2, so match it to the line size and the air demand of the downstream circuit - larger sizes (400, 600) carry larger ports and serve higher demand. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. The drain here is differential-pressure (the default); automatic (code A) and manual (code M) drains are available if you prefer hands-off or scheduled draining. Filter grade is the 40 um standard element; specify the W code where a 5 um element is required. The gauge on this unit is the external round type reading psi; embedded square gauges and MPa or bar scales are the alternative choices. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the mounting bracket is included on this configuration.
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, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the air demand of your circuit and we will confirm the flow from the datasheet for this exact configuration before you order.
The L code specifies the low-pressure regulator type, intended for circuits that run below the standard regulator's usual setting band; the exact adjustment range for this variant is not published in the material we hold, so we confirm it on request. Drainage on this configuration is differential-pressure: the filter bowl discharges condensate automatically as the pressure drop across the element builds, with no manual draining required.
