Airtac GF Filter GF400C10AJW
The AirTAC Airtac GF Filter GF400C10AJW 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 GF400C10AJW
GF400C10AJW 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 - it removes water and particulate from compressed air, with no regulator and no lubricator. The W suffix selects the finer 5 um element instead of the standard 40 um, the automatic drain (A) empties the polycarbonate bowl without operator attention, and the J suffix means no mounting bracket is fitted.
This is a genuine AirTAC part. The GF filter family spans sizes 200 to 600 with ports from 1/8 in. to 1 in., drain choices of default differential-pressure, automatic or manual, and element grades of 40 um standard or 5 um optional. 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 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.
Model Code: Airtac GF Filter GF400C10AJW
| 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 GF400C10AJW Is Used
Spray booth gun feed
Filtering the air line that feeds spray guns in a paint or coating booth, where the 5 um element helps keep fine dirt and water out of finish work.
Case packer vacuum ejectors
Conditioning the air supplied to vacuum ejectors and cups on a carton case packer, where clean air keeps grip consistent.
Electronics pick-and-place
Supplying filtered air to pick-and-place cylinders and small actuators on an electronics assembly bench.
Is the Airtac GF Filter GF400C10AJW the Right Filter?
Choose this 400-size body with its 3/8 in. PT port when the drop needs a finer 5 um element (W); the standard grade is 40 um if general-duty filtration is enough. The automatic drain (A) keeps the bowl clear without daily visits, with the default differential-pressure drain and a manual drain (M) as the other catalogue choices. Thread is PT as standard; G (BSPP) and NPT versions are options to order, and J codes come without the optional mounting bracket. Step sizes of 200/300/400/600 cover smaller and larger ports. Since AirTAC states flow as curves rather than a single rating, send us your air demand and pressure and we will 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 GF400C10AJW FAQ
AirTAC publishes filter flow as curves against pressure, not as a single rated number, so we cannot honestly quote one figure. Give us your flow demand and working pressure and we will confirm sizing from the datasheet on request.
W selects the optional 5 um filtration grade instead of the 40 um standard element, for applications that need finer particle removal. Everything else in the code stays the same: 400 size, 3/8 in. PT port, automatic drain and no mounting bracket (J).
