AirTAC GFC300-08 Combination Unit (GFC30008ALF1W)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008ALF1W) 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 automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008ALF1W)
The AirTAC GFC series is a two-piece air preparation set: a filter regulator that removes water and particulate from compressed air and holds downstream pressure, paired with a separate lubricator that adds an oil mist for air tools. This configuration is the 300 size with PT1/4 ports, an automatic drain that ejects collected condensate without manual attention, a finer 5 um filter element, the L low-pressure regulator type, and an embedded square gauge scaled in MPa. 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), and the service temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part, supplied by airtacdistr.com across the 200/300/400/600 sizes with 1/8" to 1" ports, PT as the standard thread and G (BSPP) or NPT as order options. Across the series you can choose filter grade 40 um standard or 5 um with W, a differential-pressure, automatic or manual drain, and gauge or no-gauge variants. Because rated flow is published as curves rather than a single figure, we confirm datasheet and flow data 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 (GFC30008ALF1W)
| 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. |
| (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. |

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 (GFC30008ALF1W) Is Used
Robot gripper air prep
Conditioning, regulating and lubricating the supply to pick-and-place gripper cylinders on an electronics assembly cell, with the 5 um element protecting fine seals.
Bottling line cylinder supply
Filtering, regulating and oil-misting air to filler and capper cylinders on a beverage bottling conveyor, with the automatic drain coping with condensate between shifts.
Assembly bench air tools
Supplying regulated, lubricated air to impact drivers and nutrunners at an automotive trim bench, keeping tools fed with clean, oil-misted air at a set pressure.
Is the AirTAC GFC300-08 Combination Unit (GFC30008ALF1W) the Right Set?
Step up or down by size - 200, 300, 400, 600 - to match the flow your line needs and the port it takes; this set is size 300 with PT1/4 ports. Choose the drain style: automatic (fitted here) for unattended condensate removal, manual for periodic draining, or differential-pressure as the default. Pick 40 um for general supply or 5 um (W suffix) for finer protection downstream - this unit carries 5 um. Gauges come as the embedded square type in MPa, psi or bar scales, or you can order an N variant with no gauge. PT is the standard thread; order G or NPT where the installation specifies. Flow is published as curves, not 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 (GFC30008ALF1W) FAQ
AirTAC publishes flow for the GFC series as characteristic curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the relevant curve and datasheet figures on request before you order.
A GFC combines the filter and regulator in one body and adds a separate lubricator, so you mount two components instead of three, with fewer joints and less panel space, while still filtering, regulating and lubricating. A GC keeps all three units separate, which suits layouts that want each element positioned independently.
