Airtac GF Filter GF300C08JW
The AirTAC Airtac GF Filter GF300C08JW 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 GF300C08JW
The GF300C08JW is a genuine AirTAC G-series air filter for compressed air. Its job is filtration only - removing water and particulate, with no pressure regulation and no lubrication. This configuration is a size 300 unit with a 1/4 inch PT port, the optional fine 5 um (W) element instead of the standard 40 um grade, the default differential-pressure drain, and no mounting bracket (J). Maximum working pressure is 1.0 MPa (145 psi) and the operating range is -5 to 70 C, non-freezing.
The 300 frame carries a PC (polycarbonate) bowl. Across the GF range you can choose sizes 200 to 600, ports from 1/8 to 1 inch, automatic or manual drains instead of the differential-pressure default, 40 um or 5 um elements, a bracket, and G (BSPP) or NPT threads in place of PT. AirTAC publishes filter capacity as flow curves rather than a single rated figure, so we confirm flow and other datasheet numbers 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 GF300C08JW Is Used
Electronics assembly cells
Fine 5 um filtration at electronics assembly cells, guarding pick-and-place and electric-screwdriver air feeds from fine contamination.
Process valve actuation
Conditioning air to pneumatic valve actuation packages, where the differential-pressure drain keeps condensate away from actuator internals.
Pneumatic test rigs
Clean supply filtration on pneumatic test rigs, paired with the 1/4 inch PT port for compact rig plumbing.
Is the Airtac GF Filter GF300C08JW the Right Filter?
Choose size 300 with the 1/4 inch PT port for mid-range machine supply; step up to size 400 or 600 where port size and air demand grow, or down to size 200 for compact points. The 5 um element is the finer catalogue grade for cleaner-air duties; the standard 40 um element remains available in the same size. This unit keeps the default differential-pressure drain - specify A for automatic or M for manual draining if your installation prefers it. PT is the standard thread, with G (BSPP) and NPT as catalogue options, and the J code means no bracket. Flow is published as curves, not a single rating, so 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 GF300C08JW FAQ
AirTAC publishes GF300 capacity as flow curves across the pressure range rather than a single rated figure, so no flow number is quoted here. Tell us your working pressure and air demand and we will confirm the sizing and datasheet figures on request.
PT is the standard thread on this GF300 unit, as shown in the port code. G (BSPP) and NPT are catalogue options you can order instead - they are a specification choice made at ordering, not a delivery promise.
