Airtac GF Filter GF400C10J
The AirTAC Airtac GF Filter GF400C10J 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 GF400C10J
GF400C10J is an AirTAC G-series air filter in the 400 size with a 3/8 in. PT threaded port. It is a filtration-only unit, removing water and particulate from compressed air - no regulator and no lubricator. This version uses the default differential-pressure drain, which purges collected water from the polycarbonate bowl using the pressure drop across the standard 40 um element as air flows, and the J suffix means no mounting bracket is supplied.
This is a genuine AirTAC part. The GF filter range runs from size 200 to 600 with 1/8 in. to 1 in. ports, drain choices of differential-pressure (default), automatic or manual, and 40 um standard or 5 um optional elements. Maximum working pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so we confirm sizing and the full datasheet 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.

| 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 GF400C10J Is Used
Press shop air header
Filtering the header air feeding clamps and ejection cylinders on a mechanical press line with steady, continuous demand.
Truck service bay drops
Conditioning shop air at vehicle service bays where impact guns and tire equipment run through regular working shifts.
Maintenance shop outlets
Cleaning the general-purpose air at maintenance shop outlets that feed hand-held pneumatic tools and blowguns.
Is the Airtac GF Filter GF400C10J the Right Filter?
The 400 body with a 3/8 in. PT port is the mid-large step in the GF range; move to 200/300 or 600 if the pipe and air demand call for it. Drain type is the key choice: this model uses the default differential-pressure drain, which clears the bowl on the pressure drop of flowing air and suits lines with steady use, while automatic (A) and manual (M) drains are catalogue alternatives. Element grade is the standard 40 um, with W giving 5 um. Thread is PT as standard and G (BSPP) or NPT are options to order; J codes such as this one come without the optional bracket. Since flow is published as curves and not a single rating, send us your demand and pressure so we can confirm sizing from 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 GF400C10J FAQ
AirTAC publishes filter capacity as flow curves rather than a single rated figure, so there is no one flow number to quote. Share your required flow and working pressure and we will confirm sizing from the datasheet on request.
The differential-pressure drain is the default on GF filters: as air flows through the element it creates a pressure drop that purges collected water from the bowl. It suits lines in steady use. Automatic (A) and manual (M) drain versions are catalogue options if your usage is light or unattended.
