Airtac GF Filter GF300C15MJW
The AirTAC Airtac GF Filter GF300C15MJW 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 GF300C15MJW
GF300C15MJW is an AirTAC G-series air filter for compressed air only - it removes water and particulate; there is no regulator and no lubricator in this family. The W suffix selects the finer 5 um element instead of the 40 um standard, and the J suffix deletes the mounting bracket, so the unit is supported by its pipework or panel. The 300 size carries a 1/2 in PT (standard) port, the M suffix gives a manual drain on the PC (polycarbonate) bowl, maximum inlet pressure is 0-0.9 MPa for this manual-drain filter, and the operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part, available across the G-series 200/300/400/600 sizes with a choice of ports and threads (PT standard, G and NPT as catalogue options) and drain types. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm datasheet and flow 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 GF Filter GF300C15MJW
| 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.

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 GF300C15MJW Is Used
Pneumatic logic and instrument air
Finer 5 um particle capture ahead of air-operated instrumentation and pneumatic logic devices on process lines, with condensate drained manually at checks.
Valve-matrix protection
Protecting closely-tolerated solenoid valves on an automated valve matrix from grit and slugged water, mounted in-line without a bracket.
Machine tool pneumatic circuits
Pre-filtration for clamping and tool-change circuits on CNC machine tools where the 5 um element reduces particle carry-over to the valves.
Is the Airtac GF Filter GF300C15MJW the Right Filter?
The W in this code is the key choice: the 5 um element captures finer particles than the 40 um standard, which suits more sensitive downstream equipment - note it loads faster, so manual draining and element checks matter more. The J suffix omits the bracket (order GF300C15MW if you want the bracket included with the same 5 um element). Drain is manual (M) on the PC bowl; automatic (A) and differential-pressure variants exist for unattended lines. Port is 1/2 in PT as the standard; G (BSPP) and NPT are ordered options.
Flow for sizing is published as curves, not a single rating, so ask us to confirm datasheet figures against your 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 GF300C15MJW FAQ
AirTAC publishes filter performance as curves rather than a single rated-flow figure, so there is no one number to quote. Share your line pressure and demand and we will confirm the correct size and the datasheet figures on request before you order.
W selects the 5 um filter element in place of the 40 um standard grade - a finer particle capture for more sensitive downstream equipment. Everything else in the code stays the same: 300 size, 1/2 in PT port, manual drain, no bracket.
