The AirTAC AirTAC GF300-08 Filter (GF30008MW) is a genuine G-series air filter. It separates condensed water and filters particulate from the compressed-air line through a 5 µm element, with PT1/4" 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.
The GF30008MW is an AirTAC G-series air filter: it removes water and particulate from compressed air, with no regulation and no lubrication. Built in the 300 size with a 1/4 in PT port, it carries the finer 5 um element (the W code) and a manual drain, so an operator bleeds condensate from the polycarbonate bowl by hand. Unlike the J-coded versions, this unit includes the mounting bracket for secure fixing to a machine frame or panel. Working inlet range for this manual-drain configuration is 0-0.9 MPa.
This is a genuine AirTAC part, not an imitation. The GF family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, 40 um or 5 um (W) filtration, a choice of drain type, and PT as the standard thread with G (BSPP) and NPT as catalogue options. AirTAC publishes flow as performance curves rather than a single rating, so we confirm datasheet 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.
| GF300 | G-series air filter, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 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. |
| W | Filtering grade 5 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.

Bracket-mounted inside a CNC machine's electrical cabinet, it cleans the 1/4 in supply feeding tool-changer actuation and air-blast chip clearing, with the 5 um element guarding fine pilot valves; the manual drain is bled during scheduled maintenance.
Fixed to the frame of a benchtop pick-and-place station, it removes moisture and fine particulate before they reach the vacuum generator and X-Y air cylinders, and the bracket keeps the bowl vertical for correct drainage.
Mounted beside a bank of pneumatically actuated process valves, it conditions the 1/4 in pilot line so positioners and solenoid pilots stay free of condensate and 5 um-level debris, drained manually each round.
The 300 size is the mid-range GF step with a 1/4 in PT port; drop to 200 or rise to 400/600 if porting or air demand requires. This is the 5 um (W) variant for air feeding finer equipment; the 40 um standard element suits general cylinder supply. The drain is manual, rated 0-0.9 MPa inlet - pick automatic or differential-pressure drain where no operator is available to bleed the bowl. PT thread is standard with G (BSPP) and NPT as catalogue options, and the included bracket simplifies panel or frame mounting.
Flow is published as curves, not a single rating, so ask us to confirm sizing against the datasheet before ordering.
Quick checklist
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 publishes GF-series flow as performance curves, not as a single rated figure, so we avoid quoting one here. Send us your line pressure and air consumption and we will confirm the sizing against the datasheet curves on request.
Yes. The absence of a J code in this model means the bracket is included, which keeps the unit fixed and the bowl vertical so condensate collects correctly. The J-coded GF30008MJW is the same filter without the bracket.
