Airtac GF Filter GF300C15AJW
The AirTAC Airtac GF Filter GF300C15AJW 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 GF300C15AJW
The AirTAC GF series is a straight air filter: it removes water and particulate from compressed air and does nothing else - no pressure regulation and no lubrication. The GF300C15AJW is a size 300 unit with a 1/2 inch PT port, the fine 5 um element (the W option), and an automatic drain that ejects collected condensate without anyone opening the bowl. The J option means the mounting bracket is not supplied. Because the drain is automatic, the maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C. The size 300 bowl is polycarbonate (PC).
This is a genuine AirTAC part from the G-series line, which spans sizes 200, 300, 400 and 600 with a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, and PT, G (BSPP) or NPT threads. Rated flow for this series is published as curves rather than a single figure, so ask us and we will confirm the datasheet numbers for your application 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.
Model Code: Airtac GF Filter GF300C15AJW
| GF300 | G-series air filter, 300 body — sets the port range. |
|---|---|
| C1 | 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.

- 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 GF Filter GF300C15AJW Is Used
Paint spray gun air supply
Mounted at the drop leg feeding spray guns in a finishing booth, this 5 um filter strips water and fine particles from the shop air line so moisture does not mar the paint finish. The automatic drain handles condensate even when the booth runs all shift without an operator at the filter.
Laboratory analyser air prep
Upstream of pneumatic lab instruments and sample-handling actuators, the fine 5 um element keeps particulates out of sensitive pilot circuits and the polycarbonate bowl gives a clear view of the water level, with the automatic drain keeping the bowl emptied.
Valve island inlet protection
Fitted ahead of a bank of solenoid valves on an automation line, this filter removes water and fine debris that would otherwise cause valve sticking. The 1/2 inch PT port suits the manifold supply line and the bracketless J version slots into existing panel hardware.
Is the Airtac GF Filter GF300C15AJW the Right Filter?
Start with the port: this unit is 1/2 inch PT, one step up from the 3/8 inch ports of smaller size-300 variants and below the 3/4 inch ports of the size-400 family - pick the size whose flow curve covers your consumption. Choose the 5 um element here if downstream valves, cylinders or instruments need finer air than the standard 40 um grade; the 40 um grade remains available on other GF300 codes. The automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives. Thread is PT as standard, with G (BSPP) and NPT as orderable catalogue options. If you need the bracket, order a code without the J suffix.
Flow for the GF series is published as curves, not a single rated number, so send us your air consumption and we will confirm the sizing against the datasheet before you order.
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 GF300C15AJW FAQ
AirTAC publishes flow for the GF series as performance curves rather than a single rated figure, so we do not quote one number here. Tell us your working pressure and air consumption and we will confirm the matching datasheet curve and sizing for you on request before you order.
The standard GF300 element is 40 um, which is fine for general shop-air protection of cylinders and hand tools. The W option on this code gives the 5 um element for applications with finer pneumatic components such as precision valves or instruments. If you need coarser economy filtration, order the equivalent GF300 code without the W suffix.
