AirTAC GFC300-10 Combination Unit (GFC30010LF1K)
The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010LF1K) 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 differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-10 Combination Unit (GFC30010LF1K)
The AirTAC GFC series combines a filter regulator and a separate lubricator in one two-piece set, so the circuit is filtered, regulated and lubricated in a single coordinated purchase. This GFC30010LF1K is the 300 size with 3/8 in PT ports, a differential-pressure bowl drain, standard 40 um filtration, the low-pressure (L) regulator variant, a square MPa-scale gauge and the K option, which fits a reverse/check valve so downstream pressure is held if the supply side drops.
It is a genuine AirTAC part from a series offered in sizes 200, 300, 400 and 600, with ports from 1/8 in to 1 in and a choice of drain types, filter grades, gauges and threads. As with the rest of the G series, flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your duty 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 (GFC30010LF1K)
| 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". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure 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 (GFC30010LF1K) Is Used
Robotic weld cell end-of-arm tooling
Preparing air for the grippers and clamps on a robotic weld cell, where the K option's check valve helps the tooling hold its clamp position if the main supply is momentarily interrupted during the cell cycle.
Food-plant secondary packaging machinery
Supplying the case-forming and taping heads on a secondary packaging machine in a food plant, with the filter regulator and lubricator keeping the downstream valves and cylinders consistently serviced across long production runs.
Press-side pneumatic workholding
Feeding the pneumatic workholding clamps beside a press, where maintained downstream pressure and a steady oil mist to the clamping cylinders support repeatable part location cycle after cycle.
Is the AirTAC GFC300-10 Combination Unit (GFC30010LF1K) the Right Set?
Choose this K variant over the plain GFC30010LF1 when your circuit must hold its regulated pressure against a supply interruption or when backflow could upset the process. The 300 size with 3/8 in PT ports suits mid-range circuits; move to 400/600 for more flow or 200 for compact panels. The differential-pressure drain is the default, with manual and automatic drains available as options, and the 5 um (W) element can be ordered if 40 um is too coarse. Thread is PT as standard with G (BSPP) and NPT as orderable variants; a bracket is included by default. Because flow figures are published as curves and not as a single rating, ask us to confirm sizing against the datasheet before ordering.
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 (GFC30010LF1K) FAQ
AirTAC publishes flow for the G series as curves rather than one rated number, so we do not quote a single flow figure. Share your supply pressure, working pressure and expected air consumption, and we will confirm the datasheet curve and sizing for the GFC30010LF1K on request before you order.
Both filter, regulate and lubricate. The GFC set pairs a combined filter regulator with a separate lubricator, which suits panels where a visible gauge and a compact footprint matter, while the GC keeps filter, regulator and lubricator as three separate bodies for maximum placement flexibility. This variant adds the K reverse/check valve.
