About the AirTAC GC300-15 FRL Unit (GC30015C1W)
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 MPa. In service 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 spans 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) can be specified. Flow is published as curves rather than a single rated figure, so we confirm datasheet and flow 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: GF300-15 filter, GR300-15 regulator and GL300-15 lubricator.
Size Class & How It Differs From GFC
- GC200PT1/8" - PT1/4"
- GC300PT1/4" - PT1/2"
- GC400PT3/8" - PT1/2"
- GC600PT3/4" - PT1"
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.

Where the AirTAC GC300-15 FRL Unit (GC30015C1W) Is Used
Palletizer clamp and pusher cylinders
Feeds the palletizing cell's clamp, pusher and squash-plate cylinders with filtered, pressure-stabilized and lubricated air so seals and cylinder walls stay oiled through repeated shift-long cycles.
CNC machining center tool changer
Supplies the machining center's tool changer and clamping circuit from the shop air main, keeping condensate and chips out of the actuator while holding a stable set pressure for reliable tool release.
Assembly line impact wrench drops
Point-of-use conditioning at automotive or fabricated-metal assembly stations where impact wrenches and nutrunners run continuously and need both regulated pressure and oil-mist lubrication.
Is the AirTAC GC300-15 FRL Unit (GC30015C1W) the Right Station?
This unit is size 300 with a PT1/2 port; step to GC200 for tighter lines or GC400/GC600 when port size and flow demand grow. The filter here carries the 5 um element (W); 40 um is the standard grade if finer filtration is not needed. Drain is differential-pressure; automatic (A) and manual (M) drains are catalogue options on this family, and drain type affects the regulator adjust range (0.15-0.9 MPa with differential or automatic drain, 0.05-0.9 MPa with manual drain). The gauge is a round gauge scaled in MPa; psi (2) or bar (3) scales are order options. Thread is PT as the standard, with G(BSPP) and NPT available to order. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Three-unit (GC) or two-unit (GFC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter first, lubricator last.
- check Mount vertically, bowls down.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills; check the oil level.
- check Keep the station above freezing (-5 to +70 °C, unfreeze).
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 GC300-15 FRL Unit (GC30015C1W) FAQ
AirTAC publishes flow for the G series as performance curves rather than one rated number, so there is no single figure we can quote honestly on this page. Send us your line pressure and air demand and we will confirm the flow from the GC300 datasheet on request before you order.
The C1 suffix in GC30015C1W specifies the round gauge with scale 1, which is MPa. If your team works in other units, the same size and port are available with scale 2 (psi) or scale 3 (bar) under the C2 or C3 suffix. The gauge option applies to the regulator section of the set.
