Airtac GFC Combination Unit GFC300C08AC1K
The AirTAC GFC Combination Unit GFC300C08AC1K 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 GFC300C08AC1K
GFC300C08AC1K is a two-unit air preparation set from the AirTAC G series: a filter regulator and a lubricator working together, so the downstream circuit gets filtered, regulated and oil-mist lubricated air from one assembly. It has PT1/4 ports, an automatic drain on the filter bowl, the standard 40 um filter element, a round external pressure gauge with MPa scale and a fitted reverse/check valve; the regulator setting range is 0.15-0.9 MPa (20-130 psi). Maximum working pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the 300 size uses polycarbonate bowls.
This is a genuine AirTAC part. G-series two-unit sets are available in 200, 300, 400 and 600 sizes with ports from 1/8" to 1", PT as the standard thread and G (BSPP) or NPT as catalogue options, plus a choice of drain types, 40 um or 5 um elements, gauge scales and the check-valve option. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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-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 GFC300C08AC1K Is Used
Electronics pick-and-place modules
Air preparation for the vertical cylinders of a pick-and-place module on an electronics assembly line, with the check valve helping to hold downstream pressure if the supply fluctuates.
Rotary indexing table drives
Regulated, lubricated air for the indexing cylinder of a rotary indexing table in a small assembly cell, kept free of condensate by the automatic drain.
Bench pneumatic riveting press
Conditioned supply for a bench-mounted pneumatic riveting press, with the MPa gauge letting the setter verify the working pressure before each production run.
Is the Airtac GFC Combination Unit GFC300C08AC1K the Right Set?
The 300 size with PT1/4 suits compact circuits fed at 1/4"; step up a size if the port or air demand grows. This code combines the automatic drain, the standard 40 um element, the MPa round gauge and the reverse/check valve (K); the 5 um element, other gauge scales and a manual or differential drain are all selectable alternatives.
Flow is published as curves, not a single rating, so send us your operating pressure and air demand and we will confirm the correct size against the datasheet before you order. PT is the standard thread; G (BSPP) and NPT are order options.
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 GFC300C08AC1K FAQ
AirTAC publishes flow for this series as performance curves, not a single rated figure, so we do not state one number here. Send your operating pressure and air demand and we will confirm the sizing from the datasheet on request.
It means a reverse/check valve is fitted to the set. Otherwise the code reads as GFC300C08AC1: 1/4" PT ports, 40 um element, automatic drain and a round gauge with MPa scale. Ask us if you need the valve's behaviour in your circuit confirmed against the datasheet.
