About the AirTAC GC300-15 FRL Unit (GC30015C1WK)
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, a round pressure gauge scaled in MPa, and the K suffix specifying a reverse (check) valve fitted. 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, meters oil mist to downstream tools and cylinders, and the check valve blocks backflow through the unit. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C (non-freezing). Bowls at size 300 are PC (polycarbonate).
This is a genuine AirTAC part. The same combination is available in sizes 200, 300, 400 and 600, with drain type, element grade, gauge scale, thread (PT standard; G(BSPP) or NPT as options) and the check-valve option 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.
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 (GC30015C1WK) Is Used
Bottling line capper and labeler actuators
Conditions the air feeding capper heads and labeler clamp cylinders on a bottling line, with the check valve holding the set circuit against backflow from adjacent drops on the shared header.
Conveyor gate and diverter stations
Serves sorting and diverting gates along a packaging conveyor, delivering clean, regulated, lubricated air to the gate cylinders while the check valve prevents cross-feed between branch circuits.
Pneumatic panel supply for machine cells
Mounts at the air preparation panel of an automated cell, filtering and regulating the main supply before it branches to valves and actuators, with oil mist protecting the downstream components.
Is the AirTAC GC300-15 FRL Unit (GC30015C1WK) the Right Station?
Size 300 with a PT1/2 port sits in the middle of the GC range; choose GC200 for smaller lines or GC400/GC600 for higher demand. Compared with GC30015C1W, the K suffix adds the reverse (check) valve; the plain code ships without one. The filter element here is 5 um (W), against the 40 um standard grade. Drain is differential-pressure, with automatic (A) and manual (M) as catalogue options; 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 MPa; psi or bar scales are order options. 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 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 (GC30015C1WK) FAQ
Yes, on request. AirTAC publishes flow for the G series as performance curves rather than a single rated figure, so no one number appears here. Share your inlet pressure and consumption and we will pull the GC300 datasheet and confirm the sizing for your application before you order.
K is the reverse-valve position: on this unit it specifies that a reverse (check) valve is fitted, which blocks backflow through the set. The same model without the K (GC30015C1W) is otherwise identical in size, port, thread, 5 um element, MPa round gauge and differential-pressure drain.
