AirTAC GFC300-08 Combination Unit (GFC30008MLNW)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008MLNW) 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 (GFC30008MLNW)
GFC30008MLNW is an AirTAC G-series two-unit air-preparation set: a filter regulator paired with a lubricator, so one purchase covers water and particulate removal, pressure regulation and oil-mist lubrication. This configuration decodes to PT1/4 ports in the 300 size, a 5 um fine filter element (the W grade), a manual drain you operate by hand, the low-pressure (L) regulator type and no pressure gauge in the code.
This is a genuine AirTAC part. The G-series two-unit sets come in sizes 200, 300, 400 and 600, with differential-pressure, automatic or manual drain choices, 40 um or 5 um filter grades, gauge variants and G (BSPP) or NPT thread options. The 300-size bowl is polycarbonate, working pressure is up to 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C. Because AirTAC publishes flow as curves rather than a single rating, we confirm the datasheet 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 (GFC30008MLNW)
| 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. |
| 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. |
| 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 (GFC30008MLNW) Is Used
Laboratory sample-handling actuators
Feeds the air cylinders and grippers on lab automation benches, where the 5 um element helps keep fine particles out of compact valve stacks.
Low-pressure clamping circuits
Serves as the set-and-lubricate point for fixture-clamping circuits on light machining fixtures run at modest line pressure.
Maintenance-shop air tool stations
Drops at the wall of a vehicle or plant maintenance bay to feed lubricated impact drivers, ratchets and air ratcheting wrenches at the bench.
Is the AirTAC GFC300-08 Combination Unit (GFC30008MLNW) the Right Set?
Size 300 with PT1/4 ports is the mid step of the G-series; step down to 200 for smaller ports or up to 400/600 when the line calls for larger piping. The manual drain in this code suits stations where someone passes daily; choose the automatic drain variant for hard-to-reach installs, or the differential-pressure default where a small constant bleed is acceptable. The 5 um W element is the finer choice over the standard 40 um when downstream valves and actuators need cleaner air. Thread is PT as the standard; G (BSPP) and NPT are catalogue options to order.
AirTAC gives flow as curves, not a single rated number, so ask us to confirm sizing against your working pressure and air demand 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 (GFC30008MLNW) FAQ
AirTAC publishes G-series flow as curves rather than one rated figure, so we do not quote a single number for this model. Send us your working pressure and expected air demand and we will confirm the flow curve and full datasheet figures on request.
It marks the low-pressure regulator type rather than the standard one, useful when the circuit runs at reduced line pressure. The manual-drain regulation behaviour differs from the standard type in this variant, so ask us to confirm the exact adjust range for your conditions before ordering.
