AirTAC GFC300-08 Combination Unit (GFC30008MF1)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008MF1) 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 manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008MF1)
The AirTAC GFC300 series is a two-unit air preparation set: a filter regulator plus a lubricator, so one supply line is filtered, regulated and oiled. This 300-size configuration has PT1/4 ports, a manual-drain bowl on the filter section, the standard 40 um filter element, an embedded square gauge on an MPa scale, and no reverse valve. Maximum working pressure is 1.0 MPa (145 psi); with the manual drain fitted, the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). The 300-size bowls are polycarbonate for a clear view of condensate and oil level, and the set operates from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G series spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, PT as the standard thread with G (BSPP) and NPT as catalogue options, plus drain, filter-grade, gauge, bracket and reverse-valve choices. AirTAC publishes flow as curves rather than a single rating, so ask us and we will confirm the datasheet and sizing figures 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 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 (GFC30008MF1)
| 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". |
| 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. |
| (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. |
| (blank) | Filtering grade 40 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 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 (GFC30008MF1) Is Used
Woodshop nailer and stapler drops
In a joinery running framing nailers and pin guns from a shared drop, the set strips bulk water and sawdust-laden moisture at 40 um, sets the working pressure the guns are rated for and keeps the tool seals oiled.
Bottling line gripper cylinders
On a bottling conveyor, gripper and stopper cylinders cycle continuously; this unit conditions their branch supply, holds a steady pressure so containers are not crushed or dropped, and lubricates the cylinder seals.
Maintenance-shop general air
A plant maintenance shop serving blow guns, air hammers and test rigs benefits from one conditioned outlet: filtered and regulated for the gauges and rigs on the bench, with oil mist carried to the hand tools in use.
Is the AirTAC GFC300-08 Combination Unit (GFC30008MF1) the Right Set?
The 300 size with PT1/4 ports is the middle step of the G range; move to 200 or 400/600 depending on the port your manifold needs and the air the circuit consumes. This code uses the manual drain, right for bowls you can reach on a routine round; order the A (automatic) or blank (differential-pressure) variant where access is difficult, remembering the regulator adjust range differs by drain type. The 40 um element here is the standard grade for general plant air; choose the W option for 5 um where finer filtration is needed. Gauge (square MPa here; round or other scales to order), thread (PT standard, G or NPT to order) and bracket are selectable. Flow is published as curves, not a single rating, so have us confirm sizing against the datasheet before you order.
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 0.05 - 0.9 MPa (7 - 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 (GFC30008MF1) FAQ
Not as a single number: AirTAC publishes G-series flow as curves rather than a rated figure. Share your line pressure and air demand and we will confirm the flow curve and the full datasheet for this set on request before you order.
The manual drain means you open the bowl drain by hand to remove collected condensate. If the unit sits where nobody passes regularly, choose the automatic (A) or differential-pressure (blank) version instead; note the regulator adjust range is 0.05-0.9 MPa (7-130 psi) with manual drain versus 0.15-0.9 MPa (20-130 psi) with the other types.
