AirTAC GFC300-10 Combination Unit (GFC30010AF1K)
The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010AF1K) 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 PT3/8" ports, a 40 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-10 Combination Unit (GFC30010AF1K)
This GFC300-10A-F1K is AirTAC's two-unit air preparation set - filter regulator plus lubricator - with a reverse-flow (check) valve fitted in the set for circuits where air must not pass back toward the supply. It is the 300 size with PT 3/8 in. ports, an automatic drain on the filter bowl, the standard 40 um element and the embedded square gauge reading in MPa. The regulator adjusts from 0.15-0.9 MPa (20-130 psi) at up to 1.0 MPa (145 psi) inlet; medium is compressed air, temperature range is -5 to 70 C (non-freezing), and both bowls on this 300 size are polycarbonate (PC).
This is a genuine AirTAC part. The K option is a catalogue variant of the GFC two-unit set, which also comes without the check valve, with differential-pressure or manual drains, 40 um standard or 5 um (W) elements, embedded square or external round gauges in MPa, psi or bar scales, and PT (standard), G (BSPP) or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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.
Model Code: AirTAC GFC300-10 Combination Unit (GFC30010AF1K)
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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: GFR300-10 filter regulator and GL300-10 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 GFC300-10 Combination Unit (GFC30010AF1K) Is Used
Pneumatic clamping fixtures
Prepares the supply to clamp-and-hold fixtures on a machining cell, with the fitted reverse-flow (check) valve specified for circuits where air must not flow back toward the upstream side.
Conveyor diverters and stopper stations
Feeds the cylinders that divert, stop and index product on conveyor lines, combining a 40 um filter, a set regulated pressure and a lubricator mist in one two-unit set with automatic condensate drain.
Machine-shop drop-leg air points
A prepared-air drop on the shop manifold for vises, air chucks and small actuators, with the check-valve option where the branch must stay isolated from backflow in the header.
Is the AirTAC GFC300-10 Combination Unit (GFC30010AF1K) the Right Set?
Choose the 300 size with 3/8 in. PT ports for medium-size lines; step to 200 for compact points or to 400/600 for larger ports and more flow. The K code adds the reverse-flow (check) valve - pick it when the circuit must not push air back toward the supply, otherwise order the plain F1 variant. Drain is automatic here, so condensate is ejected without operator attention; manual and differential-pressure drains are the other choices. Element is the standard 40 um; the W code gives 5 um. The embedded square gauge reads MPa, with psi/bar scales and an external round gauge as options.
Flow for the G series is published as curves, not a single rating, so tell us your application's flow and pressure and we will confirm sizing against the datasheet before you order.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GFR300-10 filter regulator on its own.
AirTAC GFC300-10 Combination Unit (GFC30010AF1K) FAQ
The G-series flow data is published as performance curves, not as a single rated figure, so we do not quote a number here. Give us your required flow and working pressure and we will confirm the size and provide the datasheet on request before you order.
It marks a reverse-flow (check) valve fitted in the set, selected for circuits where air must not pass back toward the supply. Everything else decodes the same as the plain F1: 300 size, PT 3/8 in. ports, automatic drain, 40 um element and the embedded square MPa gauge.
