Airtac GF Filter GF300C08W
The AirTAC Airtac GF Filter GF300C08W 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 GF300C08W
The AirTAC GF300C08W is a G-series air filter: it removes water and particulate from compressed air only, with no pressure regulation and no lubrication. This configuration is the size 300 body with a 1/4 in PT threaded port, the fine 5 um filter element (the W option instead of the standard 40 um), and the default differential-pressure drain, which bleeds condensate when the pressure drop across the element rises.
This is a genuine AirTAC part. The GF family is offered in sizes 200, 300, 400 and 600 with a choice of ports, thread options (PT standard, G and NPT as catalogue options), 40 um or 5 um elements, and differential-pressure, automatic or manual drains. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and the full datasheet against your application.

| Temperature range | -5 to +70 °C (unfreeze) |
| Bowl material | PC |
| Feature | Low pressure loss |
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 GF Filter GF300C08W
| 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 GF300C08W Is Used
CNC machining centre air supply
Fitted on the 1/4 in air feed to a CNC machining centre, the GF300C08W strips water and fine particles before they reach solenoid valves and spindle-seal air, using the 5 um element for finer protection than the standard grade.
Laboratory pneumatic fixtures
On bench-mounted pneumatic clamps and test fixtures in a lab, this filter cleans the compressed air feeding precision cylinders, with the differential-pressure drain keeping condensate off the work.
Control-panel instrument air
Installed ahead of pneumatic control components in a machine panel, the 5 um element and 1/4 in PT connection give a clean, compact air supply point for pilot valves and sensors.
Is the Airtac GF Filter GF300C08W the Right Filter?
Start by matching the port to your line: this unit is 1/4 in PT; step up to the size 400 or 600 GF bodies if your flow demand outgrows a 1/4 in line. Choose the 5 um element (this model) when downstream equipment needs finer filtration than the standard 40 um. The differential-pressure drain is the default; pick automatic (A) or manual (M) variants if you want hands-free or supervised draining. Thread is PT as standard, with G (BSPP) and NPT available to order, and a bracket is included on this variant. Because flow is published as curves and not a single rating, ask us to confirm sizing 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 GF300C08W FAQ
AirTAC publishes flow for the GF series as curves, not as a single rated figure, so we do not quote a number. Tell us your line pressure and air demand and we will confirm the flow curves and datasheet for this exact model on request before you order.
The W code on this model means the fine 5 um element instead of the standard 40 um. Use it when downstream valves, cylinders or instruments need finer filtration; choose the 40 um version for general-duty protection where finer grading is not required.
