AirTAC GFC300-08 Combination Unit (GFC30008MLF1W)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008MLF1W) 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 5 µm element, a manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008MLF1W)
The AirTAC GFC series combines a filter regulator and a separate lubricator in a two-piece set, so one supply line delivers filtered, regulated and oil-mist lubricated air. This GFC30008MLF1W is the 300 size with 1/4 in PT ports, a manual drain on the filter bowl, the finer 5 um (W) filter element, the low-pressure regulator type, and an embedded square pressure gauge reading in MPa.
This is a genuine AirTAC part. The G series is available in 200, 300, 400 and 600 sizes with PT, G(BSPP) or NPT threads, a choice of drains, 40 um standard or 5 um filter grades, and square or round gauges. Flow is published as curves rather than a single rating, so we 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. 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 (GFC30008MLF1W)
| 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)). |
| 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. |
| (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 (GFC30008MLF1W) Is Used
Laboratory automation
Conditioning air for the gripper and lift cylinders of a benchtop laboratory handling system, where the 5 um element keeps fine debris away from sensitive miniature valves.
Robot gripper supply
Feeding regulated, lubricated air to the end-of-arm tooling on a pick-and-place robot, with the low-pressure regulator type protecting delicate product handling.
Instrument air polish loop
Serving as the fine-filtration and regulation stage ahead of small pneumatic transmitters and indicators on a local instrumentation panel.
Is the AirTAC GFC300-08 Combination Unit (GFC30008MLF1W) the Right Set?
The 300/1/4 in step covers general machine supply; select 400 or 600 for larger ports and more flow, or 200 for compact footprints. The manual drain fits attended installations with routine bowl checks; the automatic option is there for unattended duty. The 5 um element is the finer of the two grades, protecting precision components that the 40 um standard would leave exposed, in exchange for more frequent element attention. The square MPa gauge is the embedded type; a round external gauge and psi or bar scales are also offered.
Flow is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering. PT is the standard thread; G(BSPP) and NPT are catalogue options to specify at order time.
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 (GFC30008MLF1W) FAQ
There is no single rated flow figure to quote: AirTAC publishes flow for the GFC300 series as curves. Tell us your application demand and we will confirm the appropriate sizing from the datasheet on request before you order.
The trailing W selects the 5 um filter element in place of the 40 um standard, giving finer particulate removal at the cost of more frequent element checks. The rest of the decode is the 300 size, 1/4 in PT ports, a manual drain, the low-pressure regulator type, and the embedded square gauge with an MPa scale.
