AirTAC GF400-10 Filter (GF40010)
The AirTAC AirTAC GF400-10 Filter (GF40010) 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 PT3/8" 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 GF400-10 Filter (GF40010)
The AirTAC GF series is a compressed-air filter only: it strips water and particulate out of the air line, with no pressure regulation and no lubrication. This GF40010 is the size 400 unit with 3/8in PT ports, the standard 40 micron element and the family's default differential-pressure drain. The polycarbonate bowl is standard at this size, the maximum working pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part distributed for the US market. The G-series filter line runs from size 200 to 600 with ports from 1/8in to 1in, in PT (standard), G (BSPP) or NPT thread, with differential-pressure, automatic or manual drains and 40 or 5 micron elements. AirTAC publishes filter flow as performance curves rather than a single rated figure, so we confirm sizing and datasheet 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 GF400-10 Filter (GF40010)
| GF400 | G-series air filter, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". 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.
Size Class

- GF300PT1/4" - PT1/2"
- 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 GF400-10 Filter (GF40010) Is Used
Bench pneumatic press supply
Filtering plant air feeding a bench-mounted pneumatic press, dropping condensed water and pipe scale out of the line ahead of the downstream regulator station and press cylinder.
Packaging machine air drops
Point-of-use filtration on the air drops serving a carton-forming and taping machine, catching rust particles and water carried over from the factory distribution main before they reach the machine's valves.
Workshop ring main take-offs
A general-purpose filter at take-off points on a workshop compressed-air ring main, where size 400 with 3/8in ports matches the diameter of the branch line feeding hand tools and small cylinders.
Is the AirTAC GF400-10 Filter (GF40010) the Right Filter?
Size 400 with 3/8in PT ports matches 3/8in branch lines; the step to size 600 (larger ports, higher flow capacity) or down to size 300 is a pure pipe-size and flow decision. The standard element here is 40 micron for general water and particle removal; order the W variant if the application needs the 5 micron grade. Drain choices are the differential-pressure default, automatic (A) or manual (M); threads come as PT (standard), G or NPT, and a mounting bracket is included unless a no-bracket variant is specified. Flow is published as curves rather than a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GF400-10 Filter (GF40010) FAQ
AirTAC publishes filter flow as performance curves rather than a single rated figure, so there is no one number to quote. Send us your line pressure and flow requirement and we will confirm sizing from the datasheet on request.
A blank drain position means the differential-pressure drain, which is the default for the GF family. If you prefer automatic or manual drainage, the same size 400, 3/8in unit is available as GF40010A (automatic) or GF40010M (manual).
