About the AirTAC GC300-15 FRL Unit (GC30015F1)
The GC30015F1 is an AirTAC G-series three-unit F.R.L. combination: separate filter, regulator and lubricator units forming one 3-piece set that conditions compressed air by filtration, pressure regulation and oil-mist lubrication. This configuration is size 300 with PT1/2 ports, carries the standard 40 um filter element, uses the default differential-pressure drain on the filter bowl, and includes the embedded square gauge reading in MPa. With a differential-pressure drain the regulator adjustment range is 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The G-series combination is offered in sizes 200, 300, 400 and 600 with PT, G (BSPP) or NPT threads, a choice of drain types, filter grades (40 um standard, 5 um optional) and gauge scales; maximum inlet pressure is 1.0 MPa (145 psi) and temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, 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 (GC30015F1) Is Used
Pneumatic valve manifold supply
Conditioning supply air upstream of a solenoid-valve manifold running production machinery, where the regulator setpoint holds actuator speed consistent and the lubricator extends valve and cylinder life.
Assembly-station air drops
Serving bench-mounted air tools and small press cylinders at assembly stations, giving each station its own filtered, regulated and lubricated feed with a local MPa pressure readout.
Robotic cell gripper circuits
Supplying the gripper and clamp actuators of a robotic work cell, where clean 40 um filtered air and stable regulated pressure keep pick-and-place cycles repeatable.
Is the AirTAC GC300-15 FRL Unit (GC30015F1) the Right Station?
Size 300 with PT1/2 ports suits lines whose air demand sits between the smaller 200 series and the larger 400/600 sets; match the port to your existing pipe and step the size up or down according to the flow curve, not just the fitting. This code uses the differential-pressure drain (default), which self-bleeds the bowl as pressure drop accumulates - specify M for manual or A for automatic draining in codes otherwise identical. The standard 40 um element covers general supply-air duty; add W for the 5 um grade where finer filtration is needed. The embedded square gauge reads in MPa, with psi and bar scale options available. Thread is PT as standard; G (BSPP) and NPT versions and the mounting bracket are catalogue options to order.
Since flow is published only as curves with no single rated number, 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 (GC30015F1) FAQ
AirTAC publishes flow for the G-series as performance curves, not as a single rated figure, so we do not state a number here. Send us your working pressure and required air consumption and we will confirm the flow data from the datasheet for this size 300, PT1/2 combination.
F1 specifies the embedded square gauge with an MPa scale on the regulator. This code leaves the drain position blank, which is the differential-pressure type: the bowl bleeds condensate automatically as the pressure differential builds. Codes with M or A in that position select manual or fully automatic draining instead.
