AirTAC GFC300-08 Combination Unit (GFC30008F1K)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008F1K) 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 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008F1K)
The AirTAC GFC series combines a filter regulator and a lubricator as a two-unit set, so one line-up cleans and regulates compressed air and then feeds oil mist to downstream equipment. This GFC30008F1K is the 300 size with PT1/4 ports and a reverse (check) valve fitted at the inlet side of the set. The filter section uses a differential-pressure drain with the standard 40 um element, and the regulator carries an embedded square gauge with an MPa scale, adjusting from 0.15 to 0.9 MPa (20-130 psi).
This is a genuine AirTAC part for compressed air, rated to 1.0 MPa (145 psi) working pressure and -5 to 70 C (non-freezing), with polycarbonate (PC) bowls at the 300 size. The series also covers 200/400/600 sizes, G and NPT thread options, automatic and manual drains, and a 5 um (W) filter grade. Flow is published as curves rather than a single rated figure, so 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. 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 (GFC30008F1K)
| 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)). |

| F | Gauge shape: Square. C is round, F is square. |

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 (GFC30008F1K) Is Used
CNC fixture clamping circuits
Regulates air to power clamps on a machining fixture; the fitted reverse (check) valve blocks reverse flow at the unit if the upstream supply is shut off mid-cycle.
Heavy vehicle service workshop
Feeds impact guns and brake-work stations on PT-threaded shop air drops, filtering line water and rust scale while the lubricator oils tool motors in use.
Palletising cell air preparation
Supplies the cylinders and grippers of a bag or carton palletiser, giving one setting point for line pressure and continuous oil mist for the actuators.
Is the AirTAC GFC300-08 Combination Unit (GFC30008F1K) the Right Set?
Pick the size against the flow demand of the circuit; the 300 size with 1/4 in. PT ports fits compact machine supply drops. The K suffix adds a reverse (check) valve - choose it where backflow at the unit must be blocked, and the plain suffix where it is not needed. Drains come as differential-pressure (this model), automatic or manual; filtration is 40 um standard with a 5 um (W) option; and gauge scales are 1 = MPa, 2 = psi, 3 = bar. Flow is published as curves, not a single 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 (GFC30008F1K) FAQ
AirTAC publishes flow for the G series as curves, not as a single rated number, so no one figure is quoted here. Send us your application details and we will confirm the flow and datasheet figures for this model on request before you order.
K means a reverse (check) valve is fitted with the set, so reverse flow through the unit is blocked. The same model without the K suffix carries no check valve; port, drain, filter grade and gauge are otherwise the same 300-size PT1/4 configuration.
