Airtac GF Filter GF300C08
The AirTAC Airtac GF Filter GF300C08 is a genuine G-series air filter. It separates condensed water and filters particulate from the compressed-air line through a 40 µm element, with See datasheet ports and a differential-pressure drain. A filter does not set downstream pressure — pair it with a GR regulator, or use a GFR filter regulator, when pressure control is needed.

About the Airtac GF Filter GF300C08
GF300C08 is an AirTAC G-series compressed air filter - filtration only, with no regulator and no lubricator. It is the size 300 body with a 1/4 in PT (code 08) port and the standard 40 um element, fitted with the default differential-pressure drain and a mounting bracket. Condensate and particles collect in the polycarbonate bowl; maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. Around this configuration the GF family offers sizes 200/300/400/600, ports from 1/8 to 1 in, 40 um or 5 um elements, differential-pressure, automatic or manual drains, and the J option to delete the bracket; the size 600 bowl is aluminium alloy while this size 300 bowl is PC. Flow data is published as curves rather than a single rating, so we confirm the figures and the datasheet on request.

Specifications follow the official AirTAC G-series air-preparation data. The inlet-pressure band is set by the drain type: automatic and differential-pressure drains run 0.15 - 1.0 MPa, a manual drain runs 0 - 0.9 MPa. Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| GF300 | G-series air filter, 300 body — sets the port range. |
|---|---|
| C0 | Port size See datasheet. This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain. Options are differential (blank), automatic (A) or manual (M). |
| (blank) | Mounting bracket included. A bracket ships by default; J orders it without. |
| (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. |
Field order is size, port, drain, bracket, grade, thread — a blank position takes the default. Example: GF300-10AJW is a 300 body, PT3/8", automatic drain, no bracket, 5 µm element, PT thread.

A larger body carries a larger port and passes more air at the same pressure drop. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom rather than from a single rated figure. The GF600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Where the Airtac GF Filter GF300C08 Is Used
Assembly bench air tools
Filters the line feeding impact drivers and ratchets at a small assembly bench, catching water and pipe scale before they reach the tools.
Valve manifold cabinet feed
Protects the solenoid manifold inside a machine control cabinet, sitting immediately upstream of the 1/4 in valves it supplies.
Carton sealer cylinders
Cleans air for the fold-and-tape cylinders on a carton sealing conveyor, a duty where the 40 um element and differential-pressure drain are sufficient.
Is the Airtac GF Filter GF300C08 the Right Filter?
At 1/4 in PT, this size 300 unit is the common choice for machine-level air drops. Step to size 200 for compact 1/8-1/4 in circuits or to 400/600 for larger ports and flow. The 40 um element is standard; order the W suffix for 5 um. Drainage options are the differential-pressure drain fitted here, automatic (A) or manual (M). Thread is PT as standard, with G (BSPP) and NPT available as catalogue options, and a bracket is included unless J is specified. Because flow is shown as curves, not a single number, ask us to check the size against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (See datasheet here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain: differential, automatic or manual
- ✓ Manual drain caps inlet at 0.9 MPa
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Bracket needed, or order with J
Installation & Maintenance Notes
- check Mount vertically, bowl down, and follow the airflow arrow.
- check Put the filter first in the air-preparation line.
- check Keep inlet pressure within 0.15 - 1.0 MPa (22 - 145 psi).
- check Drain condensate before the bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Replace the 40 µm element when pressure loss rises.
The PC bowl must not be cleaned with solvents or exposed to synthetic oils that attack polycarbonate — wipe it with a dry cloth. A filter removes water and particulate only; it does not regulate pressure or add lubrication.
Airtac GF Filter GF300C08 FAQ
AirTAC publishes filter flow as pressure-drop curves rather than a single rated figure, so we do not state a number here. Give us your line pressure and air demand and we will confirm the correct size and provide the datasheet figures on request.
GF300C08 is filtration only - water and particulate removal with a drain bowl, no pressure adjustment. A GFR filter-regulator combines both functions in one body and adds a gauge and an adjustment range; if you also need lubrication, look at the GC three-unit F.R.L. We can confirm the datasheet for any of these on request.
