AirTAC GFC300-08 Combination Unit (GFC30008NWK)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008NWK) 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 differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008NWK)
GFC30008NWK is a two-piece AirTAC G-series set that pairs a filter regulator with a lubricator, so one assembly filters, regulates and oil-mist lubricates the compressed air. This unit is size 300 with PT1/4 ports, carries the finer 5 um (W) filter element, uses the default differential-pressure drain on the filter bowl and has a reverse (check) valve fitted; no gauge is included. With the differential-pressure drain, the regulator adjusts 0.15-0.9 MPa (20-130 psi).
It is a genuine AirTAC part for compressed air, rated to a maximum working pressure of 1.0 MPa (145 psi) and -5 to 70 C (non-freezing). The GFC two-unit family covers sizes 200, 300, 400 and 600 in 1/8 to 1 inch ports, with drain, filter-grade, gauge, thread and check-valve options. Flow is published as curves rather than a single rated figure, so we confirm datasheet figures 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 0.15 - 0.9 MPa (20 - 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 (GFC30008NWK)
| 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". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard 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. |

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 (GFC30008NWK) Is Used
Assembly-bench torque drivers
Supplies filtered, regulated and lubricated air to pneumatic screwdrivers on an appliance assembly bench; the 5 um element helps keep grit out of the trigger valves and the check valve blocks backflow through the set.
Robot gripper valve island
Feeds a small solenoid-valve manifold on a pick-and-place gripper cell; regulation steadies the supply to the valves and the lubricator carries oil mist to the gripper cylinders.
Carton-erector cylinders
Prepares air for the fold-and-seal cylinders on a cartoning machine; the differential-pressure drain handles condensate in the filter bowl without a manual draining routine.
Is the AirTAC GFC300-08 Combination Unit (GFC30008NWK) the Right Set?
Step through sizes 200, 300, 400 and 600 and the matching 1/8 to 1 inch ports to suit the machine's air demand; because flow is published as curves, not a single rating, ask us to check sizing against your application before ordering. This configuration uses the differential-pressure drain (automatic and manual drains are the other decodable choices) and the 5 um (W) element instead of the 40 um standard - a good match upstream of precision valves and air tools.
The N suffix means no gauge is fitted; gauges with MPa, psi or bar scales can be specified instead. PT is the standard thread, with G (BSPP) and NPT available as catalogue options to order. The K suffix fits a reverse (check) valve; omit it for a plain set.
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 (GFC30008NWK) FAQ
AirTAC publishes G-series flow as performance curves, not a single rated figure, so we do not quote a rated flow number for this set. Share your machine's air demand and line pressure and we will confirm the correct size against the datasheet on request.
40 um is the standard GFC filter grade, and the W suffix orders the finer 5 um element. This unit carries W, so the set filters to 5 um - a good choice upstream of precision valves, air motors and hand tools. With the differential-pressure drain, the regulation range stays 0.15-0.9 MPa (20-130 psi).
