AirTAC GF400-15 Filter (GF40015JW)
The AirTAC AirTAC GF400-15 Filter (GF40015JW) 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 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 GF400-15 Filter (GF40015JW)
The GF40015JW is an AirTAC G-series air filter: it removes water and particulate from compressed air only - it carries no regulator and no lubricator. It is built on the 400 frame with a 1/2 in PT port and fitted with the finer 5 um (W) element instead of the standard 40 um grade, for applications where downstream valves, cylinders or instruments need cleaner air. Condensate is handled by the differential-pressure drain, the family default, and the J suffix means no mounting bracket, so the body is mounted directly in the line. 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 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 (GF40015JW)
| 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". |
| (blank) | Drain: Differential-pressure 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.

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 (GF40015JW) Is Used
Lab Instrument Air Feed
Fitted on the supply line to analytical lab instruments that use air actuation, the 5 um element filters out particulate and water that the standard grade could pass, with direct inline mounting at the bench drop.
Textile Machine Jet Circuits
Installed on the feed to jet and nozzle circuits on a textile machine, the 5 um grade helps keep fine orifices clear of debris and moisture, with the differential-pressure drain clearing the bowl as drop builds.
Process Valve Actuator Supply
Placed ahead of pneumatic actuated process valves on a plant skid, the filter delivers 5 um air to positioners and pilot valves, mounting directly in the 1/2 in line without a bracket.
Is the AirTAC GF400-15 Filter (GF40015JW) the Right Filter?
Match the frame to the pipe: the 400 size with a 1/2 in PT port is the mid-range GF choice, and the 600 size is the step up in port and flow when a line demands more. This code keeps the differential-pressure drain - the self-acting family default - and upgrades the filtration to the 5 um W element, the right call when the standard 40 um grade is too coarse for the downstream components. Thread is PT as standard with G (BSPP) and NPT available as catalogue options, and J means this version comes without a mounting bracket for direct inline mounting. Because AirTAC publishes flow as curves rather than a single rating, ask us to confirm sizing against your actual demand 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 (GF40015JW) FAQ
AirTAC publishes filter flow as performance curves rather than a single rated figure, so there is no one number to quote. Send us your line pressure, port size and air consumption and we will confirm the datasheet flow curve for this 400-size, 1/2 in PT unit against your application on request.
The blank code is the standard 40 um grade, which suits general protection for cylinders, tools and valves. The W suffix in this model fits the optional 5 um element, chosen when the downstream equipment - pilot valves, positioners, instruments or fine nozzles - needs finer particulate and better water removal than the standard grade provides.
