AirTAC GF300-08 Filter (GF30008AJW)
The AirTAC AirTAC GF300-08 Filter (GF30008AJW) is a genuine G-series air filter. It separates condensed water and filters particulate from the compressed-air line through a 5 µm element, with PT1/4" ports and a automatic 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 GF300-08 Filter (GF30008AJW)
The AirTAC GF30008AJW is a G-series compressed-air filter: filtration only, with no regulator and no lubricator in the unit. The W suffix selects the fine 5 um element instead of the standard 40 um, the A gives automatic condensate draining, and J omits the mounting bracket. It is a size 300 unit with a 1/4 in PT port, a polycarbonate bowl, a working pressure of 1.0 MPa (145 psi) and a -5 to 70 C operating range.
This is a genuine AirTAC part. The GF family runs in sizes 200, 300, 400 and 600 with 40 um or 5 um elements, differential-pressure, automatic or manual drain, bracket included or omitted, and G (BSPP) or NPT threads in addition to the PT standard. Flow is published as curves rather than a single rating, so we confirm datasheet and flow figures for your application on request.
AirTAC GF300-08 Filter (GF30008AJW) Technical Specifications

| Fluid | Compressed air |
|---|---|
| Inlet pressure | 0.15 - 1.0 MPa (22 - 145 psi) |
| Max. working pressure | 1.0 MPa (145 psi) |
| Temperature range | -5 to +70 °C (unfreeze) |

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.
Model Code: AirTAC GF300-08 Filter (GF30008AJW)
| GF300 | G-series air filter, 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. Options are differential (blank), automatic (A) or manual (M). |
| J | Supplied without bracket. A bracket ships by default; J orders it without. |
| W | Filtering grade 5 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.
Size Class

- GF400PT3/8" - PT1/2"
- GF600PT3/4" - PT1"
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 GF300-08 Filter (GF30008AJW) Is Used
Paint-spray booth air take-off
Placed at the air take-off feeding spray guns in a paint booth, the 5 um element cuts finer particulate reaching the gun than a standard element, while the automatic drain clears condensed moisture between coating runs.
Process pilot-valve air supply
Installed upstream of pilot-operated control valves on a process skid, it filters actuation air to 5 um so valve pilots stay free of fines, with the automatic drain keeping the bowl clear around the clock.
Electronics assembly air tools
Fitted on the air drop serving torque drivers and pick-and-place actuators at an electronics assembly bench, it supplies cleaner 5 um-filtered air for sensitive tooling, draining itself automatically between shifts.
Is the AirTAC GF300-08 Filter (GF30008AJW) the Right Filter?
Choose this code when the line needs finer pre-filtration: the 5 um W element protects downstream components more tightly than the standard 40 um grade, at the cost of ordering the W suffix. Bracket is omitted (J) for in-line or panel mounting. Drain is automatic, which suits unattended equipment; manual and differential-pressure alternatives exist in the same family.
Thread is PT as the standard for this code, with G (BSPP) and NPT available to order. If your demand sits near the top of what a size 300 body passes, consider size 400 or 600 - flow is published only as curves, not a single rated figure, 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: 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 5 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 GF300-08 Filter (GF30008AJW) FAQ
AirTAC publishes filter flow as curves rather than a single rated number, and we do not quote flow figures we cannot verify. If your application is sensitive to the difference the W element can make, send us your pressure and demand and we will confirm the datasheet flow data on request.
The W suffix selects the fine 5 um element, chosen when downstream equipment or the process tolerates less particulate than the standard 40 um grade allows; the standard grade suits general plant air. Both grades are orderable across the GF family, along with drain type, bracket or no bracket, and PT, G or NPT threads.
