AirTAC GF400-15 Filter (GF40015MW)
The AirTAC AirTAC GF400-15 Filter (GF40015MW) 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 manual 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 (GF40015MW)
The AirTAC GF40015MW is a G-series air filter for compressed air only: it removes water and particulate, with no pressure regulation and no lubrication. This 400-size unit carries a 1/2 in PT port and the W option, a 5 um element, for finer filtration than the standard 40 um grade - suited to protecting sensitive downstream valves, cylinders and instruments. Condensate collected in the PC bowl is released through the manual drain, best where an operator can bleed it on a routine. With a manual drain, the maximum working pressure is 0.9 MPa (130 psi), and the working temperature range is -5 to 70 C.
This is a genuine AirTAC part from the G series, available in sizes 200 to 600 with ports from 1/8 in to 1 in, with drain types, filter grades, thread options and bracket choices across the range. Flow is published as curves rather than a single rating, so we will confirm the datasheet figures 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 (GF40015MW)
| 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". |
| M | Drain: Manual drain. Options are differential (blank), automatic (A) or manual (M). |
| (blank) | Mounting bracket included. 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.

- GF400PT3/8" - PT1/2"
- 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 (GF40015MW) Is Used
Robot weld-cell pneumatics
Finer 5 um point-of-use filtration for the clamping and tooling air on a robotic welding cell, with the bracket-mounted filter placed for easy manual draining.
Print-press control air
Protecting the register controls and clutch valves on a printing press with 5 um filtration on the 1/2 in main supply, bracketed beside the machine frame.
Conveyor gate actuators
Conditioning the air feeding divert-gate actuators on a parcel conveyor, keeping moisture and fine debris out of the directional valves on a busy sortation line.
Is the AirTAC GF400-15 Filter (GF40015MW) the Right Filter?
This configuration combines a 400-size body, a 1/2 in PT port, a 5 um W element and a bracket included - a good default when you want finer filtration and a ready panel or wall fixing. If coarse protection suffices, drop the W for the 40 um standard; if the bowl is hard to reach, consider the automatic-drain variant instead of manual. Smaller demands may suit the 200/300 sizes with 1/8 to 3/8 in ports, larger supplies the 600. Thread is PT as standard, with G (BSPP) and NPT as orderable options. Flow is only available as catalogue curves, not a single rating, so ask us to confirm datasheet sizing against your application 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 - 0.9 MPa (0 - 131 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 (GF40015MW) FAQ
No single rated flow number is published: AirTAC states filter capacity as flow curves. We do not quote l/min or SCFM values. Send us your pressure and demand details and we will confirm the datasheet flow-curve data for this exact model on request before you order.
Only the filter grade: the W version carries a 5 um element for finer particle removal, while the blank variant uses the standard 40 um element. Both are 400-size filters with a 1/2 in PT port, manual drain, bracket included and a PC bowl, rated to 0.9 MPa (130 psi) with the manual drain.
