About the AirTAC GC300-08 FRL Unit (GC30008MLF1W)
GC30008MLF1W is an AirTAC GC three-unit air-treatment combination: a separate air filter, pressure regulator and lubricator, piped together as a set. This 300-size set is ported 1/4 in with standard PT thread. The filter bowl has a manual drain and a 5 um element (code W); the regulator is the low-pressure type (code L) with a 0.05-0.9 MPa (7-130 psi) setting range for this manual-drain configuration; code F1 fits the square gauge reading in MPa. Maximum working pressure is 1.0 MPa (145 psi), service temperature is -5 to 70 C (non-freezing), and the 300-size filter and lubricator bowls are PC (polycarbonate).
This is a genuine AirTAC part. The GC series spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, plus drain, filter grade, gauge, thread and valve options to order. Flow is published as curves rather than a single rated figure, so ask us to 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 (GC30008MLF1W)
| 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 (GC30008MLF1W) Is Used
Paint line gun feed
Supplying spray guns in a finishing booth: the 5 um element strips water and fine particles that would cause fisheyes, the regulator holds a steady low gun pressure, and the lubricator can be set to feed almost nothing where dry air is required.
Assembly tool station
Feeding impact drivers and nutrunners at a bench on an automotive assembly line: the regulator holds tool torque-relevant pressure, the lubricator carries a light oil mist to the tool motor, and the manual drain is bled at shift start.
Bottling line cylinders
Air supply for pusher and stopper cylinders on a bottling conveyor: filtered, regulated and lubricated air keeps the cylinders and valve seals working, with the 5 um grade protecting the small control valves on the line.
Is the AirTAC GC300-08 FRL Unit (GC30008MLF1W) the Right Station?
Step across the size range (200, 300, 400, 600) to match the port and flow of your circuit; 300 with 1/4 in PT suits compact machine supply lines. Choose the drain type: manual (this set), automatic, or the differential-pressure default - manual drain pairs with the widest 0.05-0.9 MPa setting range. Pick the 5 um element (this code) when downstream equipment needs finer air; the standard grade is 40 um. Keep the square MPa gauge, or order no-gauge, psi or bar variants. PT thread is standard, with G(BSPP) and NPT available as order options. Flow is published as curves, not a single rating - 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 (GC30008MLF1W) FAQ
AirTAC publishes flow for the G series as curves, not as a single rated figure, so there is no one number we can honestly quote. Send us your line pressure and demand and we will confirm the datasheet flow curve for this 300-size set before you order.
Manual drain means an operator opens the filter bowl drain at intervals, which suits attended machines and gives the widest 0.05-0.9 MPa (7-130 psi) regulator setting range in this configuration. Choose automatic drain if the set is on an unattended line.
