AirTAC GF400-15 Filter (GF40015AJW)
The AirTAC AirTAC GF400-15 Filter (GF40015AJW) 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 automatic 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 (GF40015AJW)
The GF40015AJW is an AirTAC G-series air filter: it removes water and particulate from compressed air only - it performs no pressure regulation and no lubrication. This unit is built on the 400 frame with a 1/2 in PT port, carries the finer 5 um (W) element instead of the standard 40 um grade, and drains condensate automatically, which suits lines that run without an operator checking the bowl. 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 the J suffix means no mounting bracket, so the body is mounted directly in the line. 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 (GF40015AJW)
| 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". |
| A | Drain: Automatic 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.

- GF600PT3/4" - PT1"
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 (GF40015AJW) Is Used
CNC Machining Cell Air Supply
Mounted at the drop feeding a CNC machining center, the 5 um element strips water and fine particulate before the air reaches solenoid valves and spindle-clamp actuators, while the automatic drain clears condensate between shifts.
Carton Packaging Line Cylinders
Installed upstream of the cylinder bank on a carton-forming conveyor, the automatic-drain bowl keeps moisture out of the pneumatics on an unattended line, protecting sealers and pushers from water carryover.
Workshop Air Drops
Fitted at service-bay and maintenance-shop air drops, the 5 um grade gives cleaner air for air tools and blow guns, and the direct line mounting without a bracket keeps the installation compact.
Is the AirTAC GF400-15 Filter (GF40015AJW) the Right Filter?
Work out the size from the pipe and the duty: the 400 frame with a 1/2 in PT port sits mid-range in the GF family, and stepping up to 600 gives a larger port and more flow. Pick the drain next - this code's automatic drain handles condensate by itself, the differential-pressure default drains on pressure rise, and a manual drain is the lowest-cost choice where someone checks the bowl regularly. Choose the 5 um (W) element where downstream valves and actuators need finer protection than the standard 40 um grade; the thread is PT as standard with G (BSPP) or NPT available as catalogue options, and J means this version ships without a bracket. Because AirTAC publishes flow as curves and not a single rating, ask us to confirm sizing against your actual air 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 (GF40015AJW) FAQ
AirTAC publishes filter flow as performance curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and air demand and we will confirm the datasheet flow curve for this 400-size, 1/2 in unit against your application before you order.
The W suffix fits the finer 5 um element instead of the standard 40 um grade, which suits sensitive downstream valves and actuators. The A suffix selects the automatic drain, which expels collected condensate on its own - a good match for unattended lines - whereas the differential-pressure default drains on pressure rise and a manual drain requires someone to operate it.
