AirTAC GFC300-10 Combination Unit (GFC30010ALF1WK)
The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010ALF1WK) 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 PT3/8" ports, a 5 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-10 Combination Unit (GFC30010ALF1WK)
GFC30010ALF1WK is an AirTAC G-series two-unit set for compressed air: a filter regulator and a separate lubricator mounted as one preparation station, with a reverse (check) valve fitted on the regulator side. This configuration is size 300 with 3/8 in PT ports, a 5 um filter element, an automatic drain on the filter bowl, and the low-pressure (L) regulator type with an embedded square gauge scaled in MPa. Maximum working pressure is 1.0 MPa (145 psi), the bowls are PC (polycarbonate) as is standard for the 300 size, and the working temperature range is -5 to 70 C (non-freezing).
The check valve is the difference from the standard set: it helps hold downstream pressure against backflow when supply is interrupted. Across the G series AirTAC offers sizes 200, 300, 400 and 600, ports from 1/8 in to 1 in, PT, G or NPT threads, 40 um or 5 um filter grades, differential-pressure, automatic or manual drains, and square or round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rating, so ask us to confirm sizing and request the datasheet.

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 GFC300-10 Combination Unit (GFC30010ALF1WK)
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". 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. |
| (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. |
| K | Reverse-flow (reflux) valve fitted. |
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: GFR300-10 filter regulator and GL300-10 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 GFC300-10 Combination Unit (GFC30010ALF1WK) Is Used
Assembly bench air tools
Runs nutrunners, impact wrenches and air screwdrivers at a workstation, with the check valve holding the set pressure at the bench against backflow while neighbouring equipment cycles on the same header.
Rapid-cycle clamp circuits, press feed
Keeps clamp cylinders on a press-feed line pressurised through fast advance-retract cycles; the reverse valve helps hold the clamped side if supply pressure dips, and the lubricator conditions the cylinder seals.
Palletiser gripper supply
Conditions air for gripper cylinders on a palletiser, where the 5 um element shields fine pilot valves and the automatic drain copes with humid summer compressor air.
Is the AirTAC GFC300-10 Combination Unit (GFC30010ALF1WK) the Right Set?
Choose this K-coded set when downstream pressure must be held if the supply dips or the set is shut off; without the K the same set is GFC30010ALF1W. The other choices are already fixed here: size 300 with 3/8 in PT ports, the finer 5 um filter grade, an automatic drain, and the low-pressure (L) regulator type. Standard automatic-drain units in the series adjust 0.15-0.9 MPa (20-130 psi); we will confirm the low-pressure adjustment range for this variant on request.
The embedded square gauge is scaled in MPa, with psi or bar scales and an external round gauge available as order options. PT is the standard thread, with G (BSPP) and NPT as catalogue options to order. AirTAC publishes flow as curves rather than a single rating, so ask us to confirm this model against your flow requirement before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GFR300-10 filter regulator on its own.
AirTAC GFC300-10 Combination Unit (GFC30010ALF1WK) FAQ
AirTAC publishes G-series flow as performance curves in the datasheet, not as a single rated figure, so we do not state a number on the page. Tell us your line pressure and air demand and we will confirm this model against the curve and send the datasheet on request.
It is the AirTAC code for a reverse (check) valve fitted on the regulator side, which helps hold downstream pressure against backflow when supply is interrupted. The set without the K, GFC30010ALF1W, is identical apart from that valve.
