Airtac GFC Combination Unit GFC300C08N
The AirTAC GFC Combination Unit GFC300C08N 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 GFC300C08N
The AirTAC GFC series is a two-unit air preparation set: a filter-regulator and a lubricator mounted together as one assembly. GFC300C08N is the 300 size with PT1/4 ports, the standard 40 um filter element, a differential-pressure drain (the default drain type for this series) and no gauge fitted. It removes water and particulate, holds the downstream pressure you set - adjustable from 0.15 to 0.9 MPa (20 to 130 psi) on this differential-drain version - and meters oil mist to the equipment behind it. Max inlet pressure is 1.0 MPa (145 psi), temperature range is -5 to 70 C, and the 300-size bowls are PC (polycarbonate).
This is a genuine AirTAC part. The G series spans 200, 300, 400 and 600 sizes with ports from 1/8 in. to 1 in., and drain type, filter grade, gauge, reverse-valve and G/NPT thread variants are catalogue choices. AirTAC publishes flow for these units as curves rather than a single rated figure, so ask us and we will confirm the flow and datasheet figures for your application before you order.

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 GFC300C08N Is Used
Assembly line pneumatic screwdrivers
Conditions the air at each screwdriver drop on an assembly line: the 40 um element removes water and coarse particles, the regulator holds the tool's set pressure, and the lubricator mists oil into the driver circuit.
Laboratory automation skid
Prepares the compressed air feeding valve manifolds and small actuators on a laboratory automation skid, where the differential-pressure drain keeps condensate off the lab's schedule and the regulator holds a steady supply pressure.
Bottling line grip cylinders
On a bottling line, the set supplies filtered, regulated, lubricated air to the gripper and stopper cylinders along the conveyor, keeping bottle handling consistent through each shift.
Is the Airtac GFC Combination Unit GFC300C08N the Right Set?
Size the set by port and flow: G series steps 200, 300, 400 and 600 cover ports from 1/8 in. to 1 in., and this 300 set carries PT1/4 as the standard thread, with G (BSPP) and NPT available to order. The 40 um element is the standard grade; choose the W-coded 5 um option where finer prefiltration is needed. The differential-pressure drain avoids a manual drain routine, while automatic and manual drain variants exist. This variant has no gauge and no reverse valve; both are available on other codes. Flow is published as curves, not a single rating - ask us to confirm 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 GFC300C08N FAQ
AirTAC publishes flow for the G series as curves, not as a single rated figure, so we do not quote one number here. Ask us and we will confirm the curve data and datasheet figures for this 300-size, PT1/4 set against your flow requirement before ordering.
N is the no-gauge code, so this set leaves the factory without a pressure gauge. If you want local pressure indication, gauged variants in the family offer an embedded square gauge or an external round gauge with MPa, psi or bar scales - order one of those codes instead.
