About the AirTAC GC300-08 FRL Unit (GC30008MF1K)
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one air-preparation set. This GC30008MF1K is the size 300 set with PT1/4 (1/4 in) ports, a manual drain on the filter bowl, a 5 um filter element, an embedded square pressure gauge on the MPa scale, and a reverse check valve fitted. It removes water and particulate from compressed air, holds a set downstream pressure and meters oil mist into the line.
This is a genuine AirTAC part. Maximum inlet pressure is 1.0 MPa (145 psi); the regulator on this manual-drain set adjusts from 0.05 to 0.9 MPa (7-130 psi); working temperature is -5 to 70 C (non-freezing); the size 300 filter bowl is polycarbonate. The GC family is also offered in sizes 200, 400 and 600, with G (BSPP) or NPT thread options and a 40 um standard element. AirTAC publishes flow as capacity curves rather than one rated figure - ask us and we will confirm the datasheet figures 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 0.05 - 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.

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 (GC30008MF1K) Is Used
Paint-booth atomizing air feed
Feeds atomizing air to spray guns in a finishing booth: the 5 um element cleans the air, the regulator holds the set gun pressure and the lubricator mists oil for the gun needle and trigger seals.
Pneumatic press cylinder supply
Supplies the downstroke cylinders on a small pneumatic press, with the check valve holding the set downstream pressure and the lubricator oiling the cylinder seals on every stroke.
Packaging line sealing jaws
Serves the sealing-jaw cylinders on a bagging line with clean, regulated, lubricated air so the timing valves and jaws keep cycling through the shift.
Is the AirTAC GC300-08 FRL Unit (GC30008MF1K) the Right Station?
Step up or down through the GC sizes (200/300/400/600) to match the port and air demand of the machine you are feeding; this size 300 set carries 1/4 in PT ports. The manual drain (M) means an operator or auto-drain trap must bleed the filter bowl periodically, and the manual-drain regulator covers 0.05-0.9 MPa (7-130 psi). The W element at 5 um suits air going to fine valves and actuators; choose the standard 40 um element where only bulk water and coarse debris matter. The square gauge reads in MPa; a bar-scale version (F3) is a separate orderable code. Thread is PT as standard - G (BSPP) or NPT versions are separate catalogue codes. Flow for GC sets is published as capacity curves, not a single rating, so please ask us to confirm sizing against your air consumption 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 (GC30008MF1K) FAQ
AirTAC publishes F.R.L. capacity as flow curves across pressure and port size, not as a single rated number, so we do not quote one figure here. Tell us your line pressure and air consumption and we will confirm the matching datasheet curve before you order.
The K in the code means a reverse check valve is fitted in the set, so air cannot flow back from the downstream side into the regulator section. If you do not need that function, order the same set without the K suffix; all other settings stay identical.
