AirTAC GF400-15 Filter (GF40015M)
The AirTAC AirTAC GF400-15 Filter (GF40015M) 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 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 (GF40015M)
The AirTAC GF40015M is a G-series air filter for compressed air: it removes water and particulate from the supply line and provides no pressure regulation and no lubrication. This 400-size unit carries a 1/2 in PT port and uses the 40 um standard element, which suits general plant air protection. The manual drain means moisture collected in the PC bowl is released by opening the drain by hand, so it fits points where an operator passes during routine checks. 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 in the 400 size of the G series, which spans sizes 200 to 600 with ports from 1/8 in to 1 in. Drain types (differential-pressure, automatic, manual), a 5 um element option, G or NPT thread options and bracket choices are available across the range. Flow for this size is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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 (GF40015M)
| 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. |
| (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 GF400-15 Filter (GF40015M) Is Used
Pneumatic press drop
Point-of-use water and particle removal on the air drop feeding a pneumatic press station, keeping the manual drain where the operator can bleed it at shift start.
Packaging machine supply
Line-side filtration ahead of the valves and cylinders on a carton packaging machine, protecting the actuators from condensed water and pipe scale on a 1/2 in supply.
Truck air bay supply
Prefiltering the shop-air feed in a commercial-vehicle service bay before it reaches impact wrenches and inflation equipment, with moisture dumped manually at the end of each job.
Is the AirTAC GF400-15 Filter (GF40015M) the Right Filter?
Start with the port step: this GF40015M gives you a 1/2 in PT connection in the 400 size; if your line is smaller or your air demand is modest, the 200/300 sizes with 1/8 to 3/8 in ports may be the better physical fit, while size 600 serves larger supplies. On drainage, manual is the right pick when the bowl is accessible and someone can bleed it regularly; choose automatic or differential-pressure drain where the unit is hard to reach. The standard element is 40 um; specify the W variant for a 5 um grade if downstream valves and cylinders need finer protection. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and the bracket is included on this configuration. Because flow is published as curves and not a single rating, ask us to confirm 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 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 GF400-15 Filter (GF40015M) FAQ
AirTAC publishes filter capacity as flow curves rather than one rated figure, so we do not quote a single l/min or SCFM number. Tell us your line size and air demand and we will confirm the datasheet flow-curve data for this exact model on request before you order.
The M in GF40015M selects the manual drain: condensate is released by hand from the bowl. It suits accessible mounting points with routine checks. If the unit sits in a hard-to-reach spot, choose the A (automatic) variant instead; note that with a manual drain the maximum working pressure is 0.9 MPa (130 psi).
