Airtac GFC Combination Unit GFC300C08F1WK
The AirTAC GFC Combination Unit GFC300C08F1WK 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GFC Combination Unit GFC300C08F1WK
The AirTAC GFC series is a two-unit air preparation set: a filter-regulator plus a lubricator, so one model filters, regulates and lubricates compressed air. This GFC300C08F1WK is size 300 with PT1/4 ports, fitted with the fine 5 um (W) filter element, a square embedded MPa gauge, the standard differential-pressure drain, and a reverse (check) valve that lets downstream pressure hold when the upstream supply is removed.
This is a genuine AirTAC part. The GFC family comes in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, in PT, G (BSPP) or NPT thread, with 40 um or 5 um filtration, automatic, manual or differential-pressure drains, and optional external round gauges. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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-C0 filter regulator and GL300-C0 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 GFC Combination Unit GFC300C08F1WK Is Used
Clamping circuit with retained pressure
On a pneumatic clamping fixture, the fitted check valve holds downstream pressure if the upstream supply drops, while the set filters, regulates and lubricates the air feeding the clamp cylinders.
Conveyor diverters and stoppers
Prepares air for stop-and-go cylinders and pop-up diverters on a conveyor line; the 5 um element protects solenoid valves and the lubricator mists oil to the actuator seals.
Pneumatic gripper cells
Feeds gripper and tool-changer circuits on a robotic cell, with regulated pressure read on the MPa gauge and the check valve helping preserve grip pressure through supply interruptions.
Is the Airtac GFC Combination Unit GFC300C08F1WK the Right Set?
Size 300 with 1/4 inch PT ports suits compact machine supply points; size up or down (200-600) to match air demand. The K code here means a reverse/check valve is fitted - specify it whenever trapped downstream pressure should be retained or backflow prevented. This unit has the 5 um (W) element and a square MPa gauge; a round external gauge on MPa, psi or bar scale is optional, and thread is PT, G or NPT at order.
Because AirTAC publishes flow as performance curves and not as one rated number, we cannot quote a flow figure here. Send us your application and we will confirm sizing against the datasheet before you order.
Quick checklist
- ✓ Body size for your peak flow (See datasheet 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-C0 filter regulator on its own.
Airtac GFC Combination Unit GFC300C08F1WK FAQ
AirTAC publishes flow for the G series as performance curves, not as a single rated figure, so no honest single number can be quoted here. Tell us your line pressure and air demand and we will confirm the datasheet curve for this exact 1/4 inch set before you order.
K means a reverse (check) valve is fitted in this filter-regulator, so downstream pressure is held against backflow when the upstream supply is lost - useful for clamps, grippers and any load that must not release. Apart from the valve, the set is identical to GFC300C08F1W: PT1/4 ports, 5 um filtration, differential-pressure drain, square MPa gauge.
