AirTAC GFC300-08 Combination Unit (GFC30008AC1)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008AC1) 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 PT1/4" ports, a 40 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008AC1)
GFC30008AC1 is a two-piece AirTAC GFC air-preparation set for compressed air: a filter-regulator body plus a separate lubricator, so filtration, pressure regulation and oil-mist lubrication come from one order. This configuration is the size 300 frame with a 1/4 in PT port, an automatic drain on the filter bowl, the standard 40 um filter element and an external round pressure gauge reading in MPa; no reverse (check) valve is fitted. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), maximum working pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C non-freezing, and the 300-size filter bowl is PC (polycarbonate).
This is a genuine AirTAC part. The GFC family runs in size 200, 300, 400 and 600 frames with ports from 1/8 in to 1 in, and options covering 40 um or 5 um elements, differential-pressure, automatic or manual drains, external round or square gauges in MPa, psi or bar scales, and a reverse/check valve. Flow for the G series is published as curves rather than a single rated figure, so we confirm the datasheet numbers 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: GFR300-08 filter regulator and GL300-08 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 GFC300-08 Combination Unit (GFC30008AC1) Is Used
Carton-sealing line actuator supply
Feeds the flap-fold and tape-head cylinders on a carton sealing conveyor: filtered, regulated and lubricated air from one set, with the automatic drain clearing condensate from the bowl through the shift.
Assembly-bench air tools
A regulated, oiled supply for nutrunners and impact drivers at an assembly bench, with the round MPa gauge giving the operator a visible set pressure at the point of use.
Compressor drop-leg point-of-use set
Installed at the take-off on a plant air ring main feeding a production cell, combining water and particle removal, pressure regulation and oil mist for everything connected downstream.
Is the AirTAC GFC300-08 Combination Unit (GFC30008AC1) the Right Set?
Decodable choices: step frame size (200/300/400/600) and port (1/8 to 1 in) against the air your circuit actually uses; drain type - A here is the automatic drain, against the default differential-pressure drain and the M manual drain; element grade - 40 um standard or W for 5 um; gauge - C1 here is the external round gauge with MPa scale, with psi (2) and bar (3) scales and square gauges as further options; and thread - PT is standard, with G (BSPP) and NPT as catalogue options. Flow is published as curves, not one rated number, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" 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 GFR300-08 filter regulator on its own.
AirTAC GFC300-08 Combination Unit (GFC30008AC1) FAQ
AirTAC publishes G-series flow capacity as curves rather than a single rated figure, so we do not quote a number here. Send us your working pressure and the air your circuit consumes, and we will confirm the sizing from the datasheet on request.
A is the automatic drain code: the filter bowl discharges collected condensate by itself, instead of the default differential-pressure drain or the M manual-drain option. It applies to the filter stage of the set.
