AirTAC GFC300-08 Combination Unit (GFC30008C3W)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008C3W) 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 5 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008C3W)
The GFC30008C3W is a two-piece air-treatment set from AirTAC's G series: a size 300 filter regulator paired with a size 300 lubricator on 1/4 in PT ports. The W code fits the finer 5 um filter element, which traps smaller particulate than the standard 40 um grade - useful ahead of pilot valves, gauges and close-tolerance tooling. Condensate collects in a polycarbonate bowl with a differential-pressure drain, the regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the lubricator meters oil mist downstream. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing. This configuration includes an external round gauge reading in bar.
This is a genuine AirTAC part. The G two-piece sets span sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in; options include manual or automatic drains, the 40 um standard element, gauge scales in MPa, psi or bar, and G (BSPP) or NPT threads instead of PT. 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.

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 (GFC30008C3W) Is Used
Air supply to lab analyser enclosures
Conditions the purge and actuation air feeding sample valves and pneumatic conveyors inside an on-line process analyser shelter. The 5 um element keeps fine pilot passages clear where the standard 40 um grade would let smaller particles through.
Pick-and-place heads on an electronics assembly cell
Feeds the vacuum ejectors and air cylinders on a PCB pick-and-place gantry. Finer 5 um filtration protects the small ejector nozzles, the regulator holds consistent placement pressure, and the lubricator services the slide cylinders.
Instrument-air backup for pneumatic transmitters on a batching plant
Conditions the supply to pneumatic transmitters and I-to-P pilot valves on a batching and dosing plant. The 5 um grade suits the tight internal clearances of instrument-grade devices, with regulated and lubricated air downstream.
Is the AirTAC GFC300-08 Combination Unit (GFC30008C3W) the Right Set?
Choose this code when the job needs the 5 um element (code W) rather than the 40 um standard grade - for example ahead of pneumatic instrumentation or fine pilot valves. Size 300 with 1/4 in PT ports is the mid step of the range; step to size 400 if demand runs high. Drain: differential-pressure here (standard), automatic (A) or manual (M) as codes - manual drain widens the regulator range to 0.05-0.9 MPa (7-130 psi). This code carries a round gauge in bar; psi and square-MPa variants exist as separate codes. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options; a mounting bracket is optional. Because flow is published as curves and not a single rating, send us your demand figures and we will confirm sizing before you order.
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 (GFC30008C3W) FAQ
AirTAC publishes G-series flow as performance curves, not as a single rated figure, so we do not state one number here. Tell us your operating pressure and air consumption and we will check the datasheet curve and confirm the sizing on request before you order.
Use the 5 um grade when the equipment downstream has fine passages that 40 um particles could foul - pilot valves, instrumentation, small ejectors and close-tolerance air tools. For general cylinder and valve service, the 40 um standard grade is usually sufficient; the two grades are ordered under their own codes.
