AirTAC GFC300-08 Combination Unit (GFC30008LC1W)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008LC1W) 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 (GFC30008LC1W)
GFC30008LC1W is a two-piece AirTAC G-series air-treatment set: a filter-regulator paired with a lubricator, delivering filtered, regulated and oil-mist-lubricated compressed air through PT1/4 (1/4 inch) ports. The W suffix specifies the finer 5 um filter element, the regulator is the low-pressure type for circuits set below standard line pressure, the bowl drains by the differential-pressure default, and an external round pressure gauge scaled in MPa is fitted.
This is a genuine AirTAC part. The G series spans 200, 300, 400 and 600 sizes with 1/8 to 1 inch ports; options across the family include automatic or manual drains, the standard 40 um element, square gauges, psi or bar scales, and G (BSPP) or NPT threads. Maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet 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. 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 GFC300-08 Combination Unit (GFC30008LC1W)
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 (GFC30008LC1W) Is Used
Laboratory actuated valves
Operating small pneumatic valves on lab benchtop and pilot-scale apparatus that run at low pressure, where the 5 um element protects fine valve seats and the lubricator keeps spools moving smoothly.
Pneumatic clamps on machining fixtures
Supplying precision clamping fixtures on a CNC fixture plate with low-pressure lubricated air, keeping the 5 um element between the shop air and the clamp's metering components.
Print head air assist on a label line
Providing filtered, regulated and lubricated low-pressure air assist to print heads and registration actuators on a label printing line, where fine filtration guards the sensitive air paths.
Is the AirTAC GFC300-08 Combination Unit (GFC30008LC1W) the Right Set?
Both units are size 300 with PT1/4 (1/4 inch) ports; move to 200, 400 or 600 if the port step should differ. The key choice here is filter grade: the W code gives the 5 um element instead of the 40 um standard - specify 5 um where downstream equipment needs finer filtration, and note the differential-pressure bowl drain, with automatic (A) or manual (M) available to order. The regulator is the low-pressure type; confirm its adjustment range against your setpoint with us. The gauge is external and round on the MPa scale; square-gauge and psi/bar variants exist. PT is the standard thread, with G (BSPP) and NPT available to order. Flow is published as curves, not a single rating, so ask us to confirm sizing against the 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 (GFC30008LC1W) FAQ
AirTAC publishes flow for this size as performance curves, not as a single rated figure, so there is no one number to quote. Tell us your working pressure and required demand and we will confirm the flow from the datasheet and verify the sizing before you order.
The only decode difference is the filter grade: W specifies the 5 um element instead of the 40 um standard, for finer protection of downstream components. Everything else matches - PT1/4 ports, low-pressure regulator, differential-pressure drain and the external round MPa gauge - and we can confirm element choice against your application on request.
