Airtac GF Filter GF300C15AW
The AirTAC Airtac GF Filter GF300C15AW 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 GF300C15AW
The AirTAC GF series is a straight air filter: it removes water and particulate from compressed air only - no pressure regulation and no lubrication. The GF300C15AW is a size 300 unit with a 1/2 inch PT port, the standard 40 um element, and an automatic drain that discharges collected condensate on its own, with the mounting bracket included. With the automatic drain, the maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C. The size 300 bowl is polycarbonate (PC).
This is a genuine AirTAC part from the G-series line, which spans sizes 200, 300, 400 and 600 with a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, and PT, G (BSPP) or NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the 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.

| GF300 | G-series air filter, 300 body — sets the port range. |
|---|---|
| C1 | Port size See datasheet. This body offers 08 = PT1/4", 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.

- 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 GF Filter GF300C15AW Is Used
Assembly-line drop leg filtration
Installed at each drop leg on an assembly line's ring main, this filter collects water condensed in the distribution piping before it reaches cylinders and air tools. The automatic drain empties the bowl continuously along the line so maintenance crews are not walking the floor to bleed bowls.
Conveyor drive cylinder protection
Feeding the pneumatic cylinders that index and stop a conveyor system, the standard 40 um element keeps pipe scale and rust particles out of seals while the automatic drain protects the drive during unattended production shifts. The included bracket simplifies mounting beside the drive frame.
Workshop impact-wrench air feed
At the wall outlet feeding impact wrenches and air ratchets in a maintenance workshop, this filter removes water that would otherwise blow out of the tool exhaust and contaminate finished work. The 1/2 inch PT port matches heavy-duty hose reels and the automatic drain keeps the bowl clear.
Is the Airtac GF Filter GF300C15AW the Right Filter?
Match the port to your line: this unit is 1/2 inch PT on the size-300 body, with size 200 (up to 3/8 inch), 400 (up to 3/4 inch) and 600 (up to 1 inch) available if your flow demand sits above or below this step. The standard 40 um element protects cylinders, valves and air tools; if you need finer air, the 5 um W option exists on other GF300 codes. The automatic drain suits unattended compressor rooms and remote drop legs; choose manual or differential-pressure drain codes where you prefer operator-controlled draining. Thread is PT as standard, with G (BSPP) and NPT as orderable catalogue options, and the bracket is supplied in this configuration.
Because flow for the GF series is published as curves rather than a single rating, send us your air demand and we will confirm the sizing from the datasheet before you order.
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 GF300C15AW FAQ
AirTAC publishes flow for the GF series as curves, not a single rated number, so we do not state a figure here. Give us your line pressure and consumption and we will confirm the correct datasheet curve and whether size 300 is the right step for you, on request.
The automatic drain on this code ejects condensate by itself whenever it accumulates, which suits unattended or hard-to-access installations and allows the full 1.0 MPa inlet pressure. The manual drain option is opened by hand to dump collected water and carries a 0-0.9 MPa inlet rating, suiting installations an operator visits regularly.
