The AirTAC Airtac GF Filter GF400C10MJW 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.
GF400C10MJW is an AirTAC G-series air filter for compressed air only. It removes water and particulate from the supply line - it does not regulate pressure and does not lubricate. This unit is the 400 size with a PT 3/8in port, fitted with the fine 5 um filter element (the W option instead of the standard 40 um), a manual drain for operator-dumped condensate, and the J option meaning no mounting bracket is fitted. The polycarbonate bowl on the 400 size makes the collected water easy to see.
This is a genuine AirTAC part. The G filter family spans 200, 300, 400 and 600 sizes with ports from 1/8in to 1in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um fine filtration, and PT, G or NPT thread options. With the manual drain fitted, the inlet working pressure range is 0 to 0.9 MPa (0 to 130 psi); working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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.
| GF400 | G-series air filter, 400 body — sets the port range. |
|---|---|
| C1 | Port size See datasheet. This body offers 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.

Installed on the compressed-air feed serving lab benches and pneumatic test rigs, the 5 um element removes fine particulate ahead of precision instruments, with the manual drain emptied as part of the lab's daily checks.
Mounted in the supply line to air-gauge and measuring stations on a quality-control bench, this filter's fine 5 um grade and clean-out bowl help keep measurement air free of water and pipe debris between operator drains.
Piped in-line ahead of a robot cell's sensor and valve instrumentation, this bracketless 3/8in body fits the cell's compact utility spine, delivering finely filtered air to the controls without disturbing existing mounting.
Size the unit through the G range (200/300/400/600) to match the port and flow path your line needs - here the 400 size gives a 3/8in PT connection. This version combines the 5 um W fine element, which protects sensitive downstream equipment better than the standard 40 um grade, with a manual drain and the bracketless J build; choose automatic or differential-pressure drain, the standard grade, or a bracketed body if your duties differ. PT is the standard thread, with G and NPT available as catalogue options.
Flow for the G filters is published as curves, not a single rated figure, so send us your flow and line conditions and we will confirm sizing against the datasheet before you order.
Quick checklist
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 publishes filter flow as performance curves rather than a single rated number, so we do not state one here. Give us your line pressure and required flow and we will confirm the datasheet curve and the right size for your application on request.
The standard 40 um grade handles general plant air, but the 5 um W element fitted here is the choice for pneumatic measuring devices, sensors, pilot circuits and finishing work where fine particles cause trouble. Note that a finer element loads faster, so pair it with the drain strategy - manual on this model - that suits how often your team can service the bowl.
