Airtac GF Filter GF400C15A
The AirTAC Airtac GF Filter GF400C15A 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 GF400C15A
GF400C15A is an AirTAC G-series air filter: it removes water and particulate from compressed air only, with no pressure regulation and no lubrication. This 400-size unit has a 1/2 in PT port, the standard 40 um element, and an automatic drain on the polycarbonate bowl, so condensate is discharged without an operator opening the bowl - useful where the unit runs unattended. A mounting bracket is included; maximum inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GF filter family is available in sizes 200, 300, 400 and 600, with 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, and PT as the standard thread with G (BSPP) and NPT as catalogue options. Filter flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing on request.
Airtac GF Filter GF400C15A Technical Specifications
| Model | Airtac GF Filter GF400C15A |

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 GF400C15A
| 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 GF400C15A Is Used
Bottling line solenoid valve supply
Conditioning air to the solenoid valve stacks on a bottling line, where the automatic drain keeps condensate out of a unit mounted above the machine and out of easy reach.
Automated press cell air feed
Filtering the supply to pneumatic clamps and ejection cylinders in an automated press cell that runs unattended between maintenance windows.
Sorting conveyor diverter air
Supplying clean air to diverter gates and stoppers along a sorting conveyor, with the 40 um element catching debris carried in from the main line.
Is the Airtac GF Filter GF400C15A the Right Filter?
Choose the size and port step to match your supply - 400 with a 1/2 in PT port here, with 200/300 and 600 either side. This code specifies the A automatic drain; pick M (manual) or the default differential-pressure drain on the same body if your maintenance routine suits them better. The standard 40 um element covers general machine air; select the W code for the 5 um element where finer filtration is needed. Thread is PT as standard, G and NPT are orderable options, and a bracket is included. Since flow is published as curves, not a single rating, ask us to confirm sizing against the application before ordering.
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 GF400C15A FAQ
Not as a single number: AirTAC publishes filter flow as performance curves rather than one rated figure. Ask us for the datasheet and we will confirm the curve for this 1/2 in, 400-size filter and check it against your application before ordering.
The A in this code selects the automatic drain: condensate is discharged without operator attention, which suits enclosed or unattended installations. Choose M (manual) if someone is already at the unit at service intervals, or the default differential-pressure drain for the standard catalogue configuration.
