About the AirTAC GC300-08 FRL Unit (GC30008MN)
The GC30008MN is a genuine AirTAC three-piece F.R.L. combination: a separate air filter, a pressure regulator and a lubricator assembled as one set, delivering filtered, regulated and oil-mist lubricated compressed air from a single mounting point. This size 300 configuration is threaded PT1/4 (PT is the standard thread; G and NPT are catalogue options), uses the M-code manual bowl drain, and carries the standard 40 um filter grade. The regulator is the standard type, no pressure gauge is fitted (N code), and no reverse/check valve is included. Maximum working pressure is 1.0 MPa (145 psi) with an operating range of -5 to 70 C, non-freezing. At size 300, the filter and lubricator bowls are PC (polycarbonate).
The G-series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and offers drain choices (differential-pressure, automatic or manual), 40 um or 5 um (W) filtration, gauge options with MPa, psi or bar scales, and an optional reverse/check valve (K). Flow for the GC30008MN is published as curves rather than a single rated figure, so we confirm the datasheet and flow curves 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 0.05 - 0.9 MPa (7 - 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.
Model Code: AirTAC GC300-08 FRL Unit (GC30008MN)
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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: GF300-08 filter, GR300-08 regulator and GL300-08 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 GC300-08 FRL Unit (GC30008MN) Is Used
CNC Machining Cell Air Prep
Feeds filtered, regulated and lubricated air to a CNC cell's pneumatics - tool changers, clamps and chip doors - with the 40 um element stopping pipe-scale from reaching directional valves.
Paint Spray Booth Supply
Conditions the air feeding spray guns on a paint line; manual drain suits a booth that is blown down and serviced at the end of every shift.
Packaging Line Actuators
Supplies carton sealers, diverters and pusher cylinders along a packaging conveyor, keeping moisture, dirt and oil supply consistent across all the stations on the line.
Is the AirTAC GC300-08 FRL Unit (GC30008MN) the Right Station?
Step up through sizes 200, 300, 400 or 600 and their port sizes (1/8 to 1 inch) against the air your machine actually consumes; the 300 size with PT1/4 suits mid-range circuits. Drain type matters: this unit is manual drain (M), so bowls are emptied on a schedule - automatic (A) or differential-pressure (default) versions exist when draining cannot be relied on. The regulation range for this manual-drain set is 0.05-0.9 MPa (7-130 psi). Filtration is 40 um standard; specify W for 5 um where finer protection is needed. This N-code set is supplied without a gauge; embedded square or external round gauges with MPa, psi or bar scales can be ordered. Thread is PT as standard, with G (BSPP) and T (NPT) as catalogue options. AirTAC publishes G-series flow 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 (PT1/4" 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 0.05 - 0.9 MPa (7 - 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC GC300-08 FRL Unit (GC30008MN) FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet and flow curve for the GC30008MN on request, then check that the size 300 / PT1/4 step matches your air demand.
Manual drain means the filter bowl is emptied by hand on a schedule - simple, low-cost and reliable where an operator already services the machine regularly. If bowls cannot be drained reliably, choose the automatic (A) or the default differential-pressure version instead; the same GC300 size is available in all three.
