AirTAC GFC300-08 Combination Unit (GFC30008F1WK)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008F1WK) 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 (GFC30008F1WK)
The AirTAC GFC series is a two-unit air-preparation set: a filter-regulator and a lubricator paired on one bracket, so you clean the air, set the working pressure and oil-mist lubricate downstream equipment from a single assembly. This 300-size configuration is ported PT1/4 with a differential-pressure drain on the bowl, a 5 um filter element for finer contamination removal than the standard 40 um element, an embedded square pressure gauge scaled in MPa, and a reverse (check) valve that helps hold downstream pressure if upstream supply dips.
This is a genuine AirTAC part. The G series spans 200, 300, 400 and 600 sizes with 1/8in to 1in ports, and the two-unit set can be ordered with automatic, manual or differential-pressure drain, 40 um or 5 um filtration, different gauge scales, and PT, G(BSPP) or NPT threads. Flow is published as curves rather than a single rating, so we confirm sizing and 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.

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 (GFC30008F1WK) Is Used
Robotic welding cell clamp circuits
Filtered, regulated and lubricated air for servo-welding cell pneumatic clamps, with the check valve helping hold clamp pressure through brief upstream supply dips.
Paint booth spray-gun supply
The 5 um element trims finer particulate ahead of spray guns on a finishing line, while the lubricator mists oil to keep trigger valves and air motors running smoothly.
Benchtop lab automation skids
A compact 1/4in supply point for small lab automation rigs where air must be cleaned, held at a set pressure and lightly oiled for cylinders and mini actuators.
Is the AirTAC GFC300-08 Combination Unit (GFC30008F1WK) the Right Set?
Start with the port and size: this 300 unit gives a PT1/4 connection; step up to 400 or 600, or down to 200, if your flow demand points to a different port. The differential-pressure drain fitted here bleeds condensate automatically while the unit is flowing; if you prefer fully automatic draining even at low flow, or a manual twist drain, both are orderable options and they change the regulator adjusting range (differential and auto drain: 0.15-0.9 MPa / 20-130 psi; manual drain: 0.05-0.9 MPa / 7-130 psi). The 5 um W element suits air that feeds finer pneumatic components; the standard 40 um element is the choice for general plant air.
Gauge scale is MPa here (psi and bar scales are alternatives), the thread is PT as standard with G and NPT as catalogue options, and the fitted reverse valve is worth keeping if your circuit must ride through brief supply dips. 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 (GFC30008F1WK) FAQ
AirTAC publishes flow for the G series as curves, not as a single rated number, so we do not quote one figure. Tell us your operating pressure and air demand and we will confirm the sizing from the datasheet curves on request before you order.
This unit has the differential-pressure drain, and with that drain type the regulator adjusts 0.15-0.9 MPa (20-130 psi). If your process needs settings below that, order the same set with a manual drain, which opens a 0.05-0.9 MPa (7-130 psi) range.
