The AirTAC AirTAC GC300-15 FRL Unit (GC30015C2W) 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 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, a pressure regulator and a lubricator, each in its own body. This configuration is size 300 with a PT1/2 port in PT thread, a differential-pressure drain on the filter bowl, a 5 um filter element, and a round pressure gauge scaled in psi. It removes water and particulate from compressed air, holds a set downstream pressure in the 0.15-0.9 MPa (20-130 psi) adjust range, and meters a controlled oil mist to lubricate downstream air tools and cylinders. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C (non-freezing). Bowl material at size 300 is PC (polycarbonate).
This is a genuine AirTAC part. The G series runs in sizes 200, 300, 400 and 600 with larger ports and flow on each step, and drain type, element grade, gauge scale and thread (PT standard; G(BSPP) or NPT as options) are selectable. Flow is published as curves rather than a single rated figure, so we confirm datasheet and flow 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 0.15 - 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: GF300-15 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 workshop rigs that service trailer air suspension and brake components, where technicians read pressures in psi directly off the gauge while the set filters, regulates and lubricates the supply.
Point-of-use preparation at maintenance tool cribs and repair benches, giving regulated, filtered and lubricated air to impact guns, ratchets and grinders on PT1/2 distribution drops.
Supplies weld-fixture and jig clamping cylinders on fabrication lines, holding a stable clamping pressure set in psi while keeping moisture and scale debris out of the actuators.
This is the size 300, PT1/2 port version of the GC combination; move to GC200 for smaller lines or GC400/GC600 as demand grows. The filter carries the 5 um element (W); the 40 um standard grade is the choice when finer filtration is not required. Drain is differential-pressure, with automatic (A) and manual (M) as catalogue options, and drain type sets the regulator adjust range (0.15-0.9 MPa with differential or automatic drain, 0.05-0.9 MPa with manual). The gauge here is a round gauge scaled in psi; MPa (1) or bar (3) scales are the alternative order codes. Thread is PT standard with G(BSPP) and NPT to order. Flow is published as curves, not a single rating, so 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.
There is no single rated flow to quote: AirTAC publishes flow for the G series as performance curves, not one number. Tell us your line pressure and air demand and we will confirm the flow from the GC300 datasheet on request so you can size the unit correctly before ordering.
The gauge scale is set by the digit after C: scale 2 (this unit, GC30015C2W) reads in psi, scale 1 reads in MPa, and scale 3 reads in bar. Pick the scale your team reads daily to avoid conversion errors at the regulator; the size, port, thread, 5 um element and differential-pressure drain are the same across the three.
