Airtac GF Filter GF400C10MJ
The AirTAC Airtac GF Filter GF400C10MJ 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 GF400C10MJ
GF400C10MJ 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, the standard 40 um filter element, a manual drain for operator-dumped condensate, and the J option meaning no mounting bracket is fitted - useful where the body pipes directly into a manifold or existing panel work. The polycarbonate bowl on the 400 size shows the collected water level clearly.
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.
Model Code: Airtac GF Filter GF400C10MJ
| 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.

Where the Airtac GF Filter GF400C10MJ Is Used
Pneumatic valve manifold pre-filter
Piped directly into the supply manifold ahead of a bank of directional control valves on a machine tool, this bracketless filter body cleans the air feeding the valve pilot ports, with the manual drain emptied during scheduled stops.
Bottling line actuator supply
Installed in the pipework feeding gripper and capper cylinders on a bottling line, the GF400C10MJ removes condensed water from the header air, and its bracketless body fits the tight spacing between existing pipe runs.
OEM machine builder panel air
Built into an OEM control panel's air preparation section, this 3/8in filter with 40 um element protects panel-mounted components, with the manual drain routed so service technicians can water out during preventive maintenance.
Is the Airtac GF Filter GF400C10MJ the Right Filter?
Choose the G size (200/300/400/600) to match the port and flow path your line needs - here the 400 size gives a 3/8in PT connection. The J code omits the mounting bracket; select the standard version if you need bracket-secured wall or panel mounting. Drain choice is manual (this M version), automatic, or the default differential-pressure type. The standard 40 um element suits general plant air, with a 5 um W option available, and PT is the standard thread with G and NPT 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
- ✓ 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 GF400C10MJ FAQ
AirTAC publishes filter flow as performance curves rather than a single rated number, so we do not quote one figure here. Share your operating pressure and consumption and we will confirm the datasheet curve and correct sizing for your application on request.
The J code means this GF400C10MJ ships without the mounting bracket, suiting installations where the body is piped in-line or panel-mounted by other means. Everything else is the same 400 size, 3/8in PT port, standard 40 um element and manual drain; order the version without J if you want the bracket included.
