AirTAC GFC300-08 Combination Unit (GFC30008AN)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008AN) 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 (GFC30008AN)
AirTAC's GFC family pairs a filter-regulator with a lubricator as a matched two-piece set: the first unit removes water and particulate and holds a set downstream pressure, while the second adds a fine oil mist for cylinders and air tools. This version is size 300 with PT1/4 ports, an automatic drain on the filter bowl, the standard 40 um filter element, standard-pressure regulation, and no gauge fitted. Maximum working pressure is 1.0 MPa (145 psi) and the regulator adjustment range with automatic drain is 0.15-0.9 MPa (20-130 psi); temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. G-series two-unit sets come in sizes 200, 300, 400 and 600, with automatic, manual or differential-pressure drain, a 5 um element option, embedded square or external round gauges in MPa, psi or bar scale, a reverse-flow check valve option, and G (BSPP) or NPT threads as catalogue alternatives to the standard PT. Because published flow appears as curves rather than a single rating, we confirm sizing 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. 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.
Model Code: AirTAC GFC300-08 Combination Unit (GFC30008AN)
| 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". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 (GFC30008AN) Is Used
Packaging line clamp cylinders
Cleaning, regulating and lubricating the air feeding clamp and pusher cylinders on a carton or shrink-wrap line, with the automatic drain handling condensate from a moist compressor room.
Assembly-station impact tools
Conditioning supply air at a bench drop where impact wrenches and nutrunners run continuously and need a steady regulated pressure plus a consistent oil mist.
Air-motor drives on processing equipment
Supplying filtered, regulated, lubricated air to vane air motors driving mixers, feeders or turntables in a plant where lubricated operation of the motor is intended.
Is the AirTAC GFC300-08 Combination Unit (GFC30008AN) the Right Set?
Size 300 with 1/4 in ports sits mid-range in the G series; step to 400 for higher demand or down to 200 for compact circuits, and ask us to check your required flow against the datasheet curves before ordering, since flow is published as curves rather than one rated figure. The automatic drain here clears condensate without daily attention; manual or differential-pressure drains are the alternatives. The standard element is 40 um; specify the W suffix for 5 um filtration. No gauge is fitted on this version, but embedded square or external round gauges in MPa, psi or bar scale can be ordered. PT thread is standard; G (BSPP) and NPT are order options.
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 (GFC30008AN) FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote one number here. Send us your line pressure, downstream demand and cycle duty and we will confirm the sizing against the datasheet curves on request.
A means the filter bowl carries an automatic drain, so condensate is expelled without daily attention. Manual (M) and differential-pressure (blank) drains are catalogue alternatives on the same 300 size if your maintenance routine suits them better.
