About the AirTAC GC300-15 FRL Unit (GC30015C3)
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, the standard 40 um filter element, and a round pressure gauge scaled in bar. 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 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 (GC30015C3) Is Used
Case-erector and taping heads
Feeds case erectors, box taping heads and flap-fold cylinders on a packaging line, giving general-purpose filtered, regulated and lubricated air for actuators that do not need fine filtration.
Pneumatic valve actuation skids
Prepares the air supply to quarter-turn pneumatic actuators and solenoid valves on process skids, holding the actuator's set pressure stable while the 40 um element stops line-scale debris.
General plant air drops on PT1/2 headers
Installed as a standard conditioning drop off a plant PT1/2 air header, serving a mixed bank of cylinders, air guns and small tools with cleaned, regulated, lubricated air.
Is the AirTAC GC300-15 FRL Unit (GC30015C3) the Right Station?
Size 300 with a PT1/2 port is the mid-range step of the GC combination; take GC200 for smaller lines or GC400/GC600 for larger ports and demand. This unit keeps the standard 40 um element; if your components need finer protection, order the W variant with the 5 um element. 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 is a round gauge scaled in bar; MPa (1) or psi (2) scales are order options. Thread is PT 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 (GC30015C3) FAQ
AirTAC publishes flow for the G series as performance curves rather than a single rated figure, so no one number can be stated here honestly. Send your inlet pressure and demand profile and we will confirm the flow from the GC300 datasheet on request before you commit to a size.
40 um is the standard grade and suits general plant air feeding cylinders, valves and air tools. If the downstream equipment has finer tolerances, such as precision pneumatic components or sensitive pilot circuits, order the W variant of the same code for the 5 um element; everything else about the set stays the same.
