About the Airtac GC FRL Unit GC300C08NK
The GC300C08NK is a genuine AirTAC G-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator supplied as one coordinated set. This configuration is size 300 with 1/4 in PT ports, a 40 um standard filter element, differential-pressure drain on the filter bowl, no gauge fitted, and a reverse (check) valve fitted. In use it cleans water and particulate from the compressed air, holds the set downstream pressure and adds oil mist for downstream tools and cylinders.
This is a genuine AirTAC part within a range that spans size 200 to 600 with 1/8 in to 1 in ports, automatic, manual or differential-pressure drains, 40 um or 5 um filtration, gauge choices and G (BSPP) or NPT threads as catalogue options. Max working pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C, non-freezing. Flow figures are published as curves rather than a single rated number, so we confirm datasheet 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-C0 filter, GR300-C0 regulator and GL300-C0 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 GC300C08NK Is Used
Pneumatic stamping press supply
Point-of-use air prep for a small pneumatic stamping or marking press: one 1/4 in set filters the supply, regulates cylinder pressure and feeds oil mist to the valve stack and seals.
Bottling line gripper cylinders
Feeding the pick-and-place gripper cylinders on a bottling or canning conveyor with cleaned, regulated and lubricated air so fast-cycling directional valves hold up over long shifts.
Laboratory automation actuators
Supplying slide cylinders and rotary actuators in laboratory automation cells from a single 1/4 in conditioning point, with the reverse valve fitted in this configuration.
Is the Airtac GC FRL Unit GC300C08NK the Right Station?
Step through G-series sizes 200 to 600 as your flow demand and port size grow; size 300 with 1/4 in PT ports suits compact machine supply circuits. With the differential-pressure drain in this code, the regulator's adjustable range is 0.15-0.9 MPa (20-130 psi); choosing a manual-drain variant widens this to 0.05-0.9 MPa (7-130 psi). Filtration is the 40 um standard grade here, with 5 um (W) available for finer protection. This code carries no gauge (N); round or square gauges with MPa, psi or bar scales can be ordered instead. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and a bracket is included by default. 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-C0 regulator with a GF300-C0 filter on that branch.
Airtac GC FRL Unit GC300C08NK FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote one number here. Send us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the sizing from the datasheet on request before you order.
N means no pressure gauge is fitted on the regulator; K means a reverse (check) valve is fitted. If you want a gauge, order a variant with a round (C) or square (F) gauge in MPa, psi or bar scale. Filtration here is the 40 um standard grade; a W code specifies the 5 um element.
