Airtac GFC Combination Unit GFC300C10AC1WK
The AirTAC GFC Combination Unit GFC300C10AC1WK 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 GFC300C10AC1WK
GFC300C10AC1WK is the same two-piece AirTAC G-series station - filter regulator plus lubricator for filtration, regulation and oil-mist lubrication - with one addition: the K suffix means a reverse (check) valve is fitted. This configuration is size 300 with 3/8 in PT ports, a 5 um filter element, automatic drain, and an external round pressure gauge scaled in MPa. The standard-pressure regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with automatic drain, maximum inlet pressure is 1.0 MPa (145 psi), and the PC (polycarbonate) bowl on the filter-regulator suits compressed air at -5 to 70 C.
This is a genuine AirTAC part. The GFC two-unit concept is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of drains, 40 um standard or 5 um filtration, square or round gauges on MPa, psi or bar scales, G (BSPP) or NPT thread options, and the K check-valve option shown here. Because flow is published as curves rather than a single rated figure, we confirm the datasheet and sizing 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.

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-C1 filter regulator and GL300-C1 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 GFC300C10AC1WK Is Used
Multi-branch tool manifolds
On a shared manifold feeding several air tool drop points, the fitted check valve blocks reverse flow between branches while the set filters, regulates and lubricates the supply to each tool station.
Case-sealing machine actuators
Carton-taper and case-sealing stations on a packaging line run cylinder-and-gripper actuators; this 3/8 in set conditions their branch feed, with the check valve holding the circuit against backflow.
Welding fixture clamp supply
Pneumatic clamps on a welding fixture line hold parts through the cycle; clean 5 um air, regulated pressure and oil mist keep the clamp cylinders working, and the check valve helps isolate the fixture circuit.
Is the Airtac GFC Combination Unit GFC300C10AC1WK the Right Set?
Size 300 on 3/8 in PT ports is the mid step of the 200/300/400/600 range; choose the size whose port matches the branch line, and let the published flow curves settle whether that step covers your demand. Automatic drain suits points that run unattended between checks; manual and differential-pressure drains are the alternatives. The 5 um (W) element is the finer of the two published grades (40 um standard). The external round gauge here is on the MPa (scale 1) scale; square-gauge bodies and psi or bar scales are selectable. PT thread is standard, with G (BSPP) and NPT as catalogue options, and the K in this code means the reverse/check valve is fitted - choose this variant only where you want reverse flow blocked. Flow is published as curves, not a single rating, so ask us to confirm sizing before ordering.
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-C1 filter regulator on its own.
Airtac GFC Combination Unit GFC300C10AC1WK FAQ
Flow for the GFC series is published as curves rather than a single rated figure, so we do not quote one rated-flow number. Give us your line pressure and air consumption and we will confirm the sizing from the datasheet on request.
K indicates that a reverse (check) valve is fitted, which blocks reverse flow back toward the regulator inlet. Everything else in the decode is unchanged: automatic drain, 5 um element, external round MPa gauge, standard regulator and 3/8 in PT ports.
