AirTAC GFC300-08 Combination Unit (GFC30008ALN)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008ALN) is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with PT1/4" ports, a 40 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008ALN)
The GFC series pairs a filter regulator - removing water and particulate from compressed air while holding downstream pressure - with a separate lubricator that meters an oil mist to air tools. This version is the 300 size with PT1/4 ports, an automatic drain that clears condensate without attention, the standard 40 um filter element, the L low-pressure regulator type, and the N option with no gauge fitted. The L suffix marks the low-pressure type; with the automatic drain the quoted adjust range is 0.15-0.9 MPa (20-130 psi), and we confirm the exact low-pressure span on request. Maximum working pressure is 1.0 MPa (145 psi); temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from airtacdistr.com, available across the 200/300/400/600 sizes with 1/8" to 1" ports, PT as standard and G (BSPP) or NPT as order options. Filter grade is 40 um standard or 5 um with W, drains come as differential-pressure, automatic or manual, and gauge-equipped variants exist where a local pressure readout is wanted. Because rated flow is published as curves, not a single figure, we confirm datasheet data 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. The set has no separate bracket code — the two 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 GFC300-08 Combination Unit (GFC30008ALN)
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure 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 set. Constituent units, orderable separately as spares: GFR300-08 filter regulator and GL300-08 lubricator.
Size Class & How It Differs From GC
- GFC200PT1/8" - PT1/4"
- GFC300PT1/4" - PT1/2"
- GFC400PT3/8" - PT1/2"
- GFC600PT3/4" - PT1"
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Where the AirTAC GFC300-08 Combination Unit (GFC30008ALN) Is Used
Woodshop nailer drop
Filtering, regulating and lubricating the branch feeding nailers and staplers at a furniture workshop bench, with the automatic drain handling overnight condensate.
Parcel sorter diverter supply
Conditioning air to the diverter and pusher cylinders on a parcel-sort conveyor, where pressure is read at the room's main panel rather than at each unit.
Lab automation actuators
Supplying clean, regulated, oil-misted air to the gripper and lift cylinders of a laboratory sample-handling station built into a closed cabinet.
Is the AirTAC GFC300-08 Combination Unit (GFC30008ALN) the Right Set?
Pick the size - 200, 300, 400 or 600 - for the flow and port your circuit requires; this unit is size 300 on PT1/4. Drain types are automatic (fitted here), manual, and the differential-pressure default. Filtration is the standard 40 um; order the W variant for 5 um where finer protection matters. The N code means no gauge, ideal for concealed panels or circuits that read pressure elsewhere - choose a square-gauge code in MPa, psi or bar scales when a local readout helps. PT is the standard thread, with G and NPT available to order. Flow is published as curves rather than one 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
- ✓ Two-unit (GFC) or three-unit (GC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter regulator 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 set 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR300-08 filter regulator on its own.
AirTAC GFC300-08 Combination Unit (GFC30008ALN) FAQ
Flow for the GFC series is published as characteristic curves, not as a single rated figure, so we do not state a number here. Share your application - the devices served and their air demand - and we will confirm the datasheet curve and sizing on request before you order.
N is the no-gauge code: the regulator is supplied without a pressure gauge, which suits panels that display pressure elsewhere. Gauge-equipped variants use the embedded square gauge in MPa, psi or bar scales, so you can switch codes whenever a local readout is wanted.
