The AirTAC Airtac GF Filter GF300C08MW 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.
The GF300C08MW is a genuine AirTAC G-series air filter for compressed air only - filtration of water and particulate, with no regulation and no lubrication. This 300-size unit has a 1/4" PT port, a manual drain so the polycarbonate bowl can be blown down as part of a scheduled routine, and the W suffix fits the finer 5 um element in place of the 40 um standard grade. The inlet pressure range for this manual-drain filter is 0-0.9 MPa (0-130 psi), and the unit comes with a mounting bracket included.
AirTAC offers the GF300 series in sizes 200, 300, 400 and 600 with ports from 1/8" to 1", a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) elements, and optional G (BSPP) or NPT threads instead of the PT standard. Flow figures appear only as curves in the catalogue - we confirm the datasheet and sizing 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. |
|---|---|
| C0 | 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 photoelectric or air-permeation sensors on a production line use a continuous clean-air purge, the GF300C08MW brackets beside the sensor junction box and filters the 1/4" PT purge feed, with the 5 um element protecting the fine purge orifices.
On a food-packaging conveyor, the cylinders that divert trays need water- and particle-free air to keep seals and spools working; this bracketed 1/4" filter sits at the head of each drop leg and is drained at the end of every run.
On a skid with small pneumatic ball and butterfly valve actuators, the GF300C08MW filters the 1/4" instrument-air branch upstream of the solenoid valves, and the manual-drain bowl is opened during the weekly maintenance walk.
Size the unit to the line: 200, 300, 400 or 600, with the port following - this one is 300 size on a 1/4" PT connection. The manual drain fits attended installations with a set drain schedule; specify A for automatic draining or blank for the differential-pressure default otherwise. Grade matters: 40 um is standard, and the W suffix fitted here selects 5 um. Thread is PT as standard, with G and NPT as catalogue options; the bracket is included on this version (order J to delete it).
Flow is published as curves, not a single rated figure, so ask us to confirm sizing against your application from 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 flow for the G series as curves across the pressure range rather than as a single rated figure, and the 5 um element is part of that flow path - so we do not quote a number here. Give us your working pressure and demand and we will confirm the datasheet figures and correct size on request.
PT is the standard thread on the GF300C08MW. G (BSPP) and NPT are catalogue thread options on the same filter, ordered as suffix variants of the code. They are specification choices on the order, and we will confirm the exact ordering code and datasheet details on request.
