About the Airtac GC FRL Unit GC300C15MNK
The GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, plumbed in line so one order covers filtration, regulation and lubrication. This GC300C15MNK is the size 300 set with 1/2in PT ports and a reverse (check) valve fitted, which holds the downstream side against backflow. The filter bowl has a manual drain and a 40 um standard element, the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi) in this manual-drain configuration, and the lubricator mists oil downstream. No gauge is fitted on this variant (N). Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of ports, thread (PT standard, G and NPT as options), drain type, filtration grade and the reverse-valve (K) option shown here. Published flow figures are curves rather than a single rating, so ask us to confirm sizing or send the datasheet for your application.

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-C1 filter, GR300-C1 regulator and GL300-C1 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 GC FRL Unit GC300C15MNK Is Used
Shared manifold on a multi-station cell
Conditioning air on a branch of a shared manifold in a multi-station assembly cell, where the check valve helps hold the regulated downstream side while neighbouring branches are vented or cycled.
Robotic palletizer gripper circuit
Supplying the vacuum generators and gripper cylinders on a robotic palletizer: filtered, regulated, lubricated air with the check valve holding the circuit against backflow between cycles.
Truck dock pneumatic door system
Preparing air for high-speed dock door actuators at a distribution center, with a 40 um element shielding the valves and oil mist extending cylinder service life.
Is the Airtac GC FRL Unit GC300C15MNK the Right Station?
Size 300 with 1/2in PT ports is the mid-range step in the GC line; move to 200, 400 or 600 as your flow and port requirements dictate. Choose the K (check valve) variant when you want the regulator setting held downstream and protected against backflow - for example on a branch that shares supply with other equipment. Manual drain suits attended installations; choose automatic or differential-pressure drain for unattended ones. The 40 um element is standard for general plant air; the 5 um (W) variant is the finer option. This variant has no gauge (N). PT is the standard thread; G (BSPP) and NPT are catalogue options. 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 (See datasheet 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-C1 regulator with a GF300-C1 filter on that branch.
Airtac GC FRL Unit GC300C15MNK FAQ
Yes - on request. AirTAC publishes GC series flow as curves rather than a single rated figure, so we do not state one number here. Send us your application details and we will confirm sizing and provide the datasheet.
K means a reverse (check) valve is fitted, so the downstream side is held against backflow - useful when the set feeds a branch that must keep its regulated pressure while neighbouring equipment vents. The base GC300C15MN without K has no check valve.
