AirTAC GF400-15 Filter (GF40015AW)
The AirTAC AirTAC GF400-15 Filter (GF40015AW) 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 PT1/2" 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 GF400-15 Filter (GF40015AW)
The GF40015AW is an AirTAC G-series air filter: it removes water and particulate from compressed air only - no pressure regulation, no lubrication. It is built on the 400 frame with a 1/2 in PT port, carries the finer 5 um (W) element in place of the standard 40 um grade, and drains condensate automatically, so the bowl looks after itself on lines that run unattended. The 400-size polycarbonate bowl is rated for a maximum inlet pressure of 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and since no J appears in the code a mounting bracket is included. AirTAC lists the GF filter as having low pressure drop.
This is a genuine AirTAC G-series part. The GF family spans the 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, differential-pressure, automatic or manual drain choices, 40 um standard or 5 um elements, and G (BSPP) or NPT thread options to order. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow figures 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 GF400-15 Filter (GF40015AW)
| GF400 | G-series air filter, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain. Options are differential (blank), automatic (A) or manual (M). |
| (blank) | Mounting bracket included. 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

- GF300PT1/4" - PT1/2"
- 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 GF400-15 Filter (GF40015AW) Is Used
Bottling Line Valve Stand
Installed on the supply to a bottling line's valve manifold, the 5 um element keeps water and fines out of the pilot valves, and the automatic drain plus included bracket make it a fit-and-forget point-of-use station.
Assembly Robot Pneumatic Feed
Mounted on the frame of a pick-and-place robot cell with the supplied bracket, the filter feeds the gripper circuit with 5 um-filtered air while the automatic drain handles condensate through long production runs.
Air-Knife Drying Station
Placed ahead of air-knife nozzles on a washdown drying station, the 5 um grade and automatic condensate drain help keep the nozzle array clear of water and particulate carryover from the shop main.
Is the AirTAC GF400-15 Filter (GF40015AW) the Right Filter?
Size the unit to the pipe and duty: the 400 frame with its 1/2 in PT port sits mid-range, and the 600 size steps up to a larger port and more flow if the line needs it. This code pairs the automatic drain - best where nobody is routinely checking the bowl - with the 5 um (W) element for finer filtration than the standard 40 um grade. The thread is PT as standard, with G (BSPP) and NPT available as catalogue options, and the included bracket gives you a clean wall or machine-frame mounting instead of stressing the pipework. AirTAC publishes flow 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 (PT1/2" 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 GF400-15 Filter (GF40015AW) FAQ
There is no single rated flow to quote - AirTAC publishes this filter's performance as flow curves only. Tell us your working pressure and air consumption and we will confirm the datasheet curve for this 400-size, 1/2 in PT unit against your application on request.
The A selects the automatic drain instead of the differential-pressure default, so condensate is expelled without an operator. The W fits the optional 5 um element in place of the standard 40 um grade, and the absence of a J code means the mounting bracket is included. The 1/2 in PT port, 400 frame and 1.0 MPa (145 psi) maximum inlet pressure stay the same.
