Airtac GFC Combination Unit GFC300C08C1K
The AirTAC GFC Combination Unit GFC300C08C1K 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 GFC300C08C1K
The AirTAC GFC is a two-unit air preparation set combining a filter regulator and a lubricator, so one assembly filters, regulates and oils the compressed air. This GFC300C08C1K is the 300 size with PT1/4 ports, the standard 40 um element and the default differential-pressure drain. The standard regulator covers 0.15-0.9 MPa (20-130 psi) in this configuration, an external round gauge with MPa scale displays the set pressure, and the trailing K means a reverse (check) valve is fitted so downstream air cannot flow back toward the supply.
This is a genuine AirTAC part from a family offered in 200 to 600 sizes, with PT threads as standard and G (BSPP) or NPT as catalogue options, 40 um or 5 um elements, and differential-pressure, automatic or manual drains. Flow data is published as curves rather than a single rating, so we confirm 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 GFC300C08C1K Is Used
Bottling line actuator supply
Conditions air for the filler and capper actuator circuits on a bottling line, with the round MPa gauge for operator set-point checks, the check valve isolating the circuit when the header is vented, and the lubricator feeding the cylinders.
Welding cell clamp circuits
Prepares air for weld-gun clamping and part-positioning cylinders in a robotic welding cell, where the check valve holds the regulated side if the cell supply is isolated between cycles.
Textile machine air rings
Supplies regulated, filtered and oiled air to the pneumatic threading and doffing circuits of spinning and weaving machines, with the visible MPa gauge simplifying routine pressure verification.
Is the Airtac GFC Combination Unit GFC300C08C1K the Right Set?
Pick this code when you want the readable round MPa gauge and the backflow protection of the check valve on a 300-size, 1/4 in set. The 40 um element and differential-pressure drain are the standard, set-and-forget choices for ordinary plant air; step to the 5 um W element if the downstream valves demand finer filtration.
The check-valve K option is worth specifying wherever a supply shutdown or upstream venting must not reverse air through the set. PT is the standard thread, with G (BSPP) and NPT available to order. Because the 300-size flow is published only as curves, ask us to confirm the datasheet and sizing against your application 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-C0 filter regulator on its own.
Airtac GFC Combination Unit GFC300C08C1K FAQ
There is no single rated flow figure we can quote: AirTAC publishes G series flow as performance curves. Ask us for the datasheet and we will read the 300-size curve at your inlet pressure and confirm the sizing for your application before you order.
This code leaves the drain position blank, so it uses the default differential-pressure drain, which discharges condensate automatically as the pressure drop across the filter element builds. The M-coded manual drain instead holds the condensate until an operator opens it, and the regulator adjustment range differs: 0.15-0.9 MPa (20-130 psi) here versus 0.05-0.9 MPa (7-130 psi) for the manual-drain variant.
