The AirTAC GC300C15MLC2 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 GC300C15MLC2 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one unit to clean, regulate and oil-mist lubricate compressed air. This configuration is built for 1/2 in PT ports (G and NPT threads are order options), carries a 40 um filter element with a manual-drain bowl, a low-pressure-type regulator fitted with a round psi gauge, and includes a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. The filter-section bowl on this unit is metal.
GC combinations are offered by AirTAC in sizes 200, 300, 400 and 600, covering ports from 1/8 in up to 1 in, with options that include automatic or differential-pressure drains, a 5 um (W) filter element, gauge scales in MPa, psi or bar, and G or NPT threads. This is a genuine AirTAC part. Flow is published as curves rather than a single rated figure, so we confirm sizing 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. 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.

Supplies filtered, regulated and lubricated air to pneumatic clamps and swing cylinders on a machining centre, keeping seal life and clamp action consistent through a shift.
Conditions the air at a spray-booth drop where a low-pressure regulator setting, clean 40 um air and a light oil mist are wanted for gun actuation and booth equipment.
Feeds cartoners, case packers and conveyor stop-gate cylinders on a packaging line, protecting valves and cylinders from water and debris while keeping lubrication steady.
Step up or down through the GC sizes (200/300/400/600) and their matching ports (1/8 to 1 in) to suit the line size and the air demand of the circuit; the 300 size here gives a 1/2 in PT connection. Choose the drain to match maintenance habits: manual (as on this unit) means an operator drains the bowl on a routine, automatic handles it unattended, and differential-pressure drains only when the element loads up. Filter grade is 40 um as standard, with 5 um (code W) where finer particulate removal matters. Gauge scale is selectable - this unit carries a round gauge reading in psi - and thread is PT as standard with G and NPT as order options. A bracket is included on this configuration.
One honest note before you order: because the regulator in this unit is the low-pressure type and its exact adjustment range is not published, and because flow is published as curves rather than a single rating, ask us to confirm the range and 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, not as a single rated figure, so there is no one number we can honestly quote. Send us your line size and air demand and we will confirm the sizing against the datasheet curves on request before you order.
L marks the low-pressure type of regulator in this combination; its exact adjustment range is not published, so we confirm it on request. M is the manual drain on the filter bowl - an operator drains it on a routine - and automatic or differential-pressure drains are available on other GC configurations if you prefer unattended draining.
