The AirTAC AirTAC GF300-08 Filter (GF30008A) 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 PT1/4" ports and a automatic 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 AirTAC GF30008A is a G-series compressed-air filter: it removes water and particulate from the air line and does nothing else - no pressure regulation and no lubrication. This size 300 unit carries a 1/4 in PT port, a 40 um standard filter element, and an automatic drain, so the bowl empties collected condensate on its own without an operator having to bleed it by hand. The polycarbonate bowl suits this non-600 size, and the working pressure is 1.0 MPa (145 psi) with a -5 to 70 C temperature range.
This is a genuine AirTAC part. The G series spans sizes 200, 300, 400 and 600, with differential-pressure, automatic or manual drain options, a 5 um element option, and G (BSPP) or NPT thread options besides the PT standard. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. |
|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic 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.

Installed at the drop feeding a pneumatic stamping press, the filter strips water and pipe-scale carried up from the compressor room before the air reaches the press valves, with the automatic drain emptying the bowl during unattended shifts.
Mounted ahead of the solenoid valves on a carton-packaging conveyor line, it keeps condensate and particulate out of the valve seats, protecting the cylinders that index boxes down the belt.
Fitted at the air inlet of a CNC machining centre's pneumatic cabinet, it conditions the supply air feeding tool-change clamps and air-blast nozzles, with the automatic drain handling condensate between cycle stops.
Size 300 with a 1/4 in PT port is a mid-range step in the G series; if your line draws more air, step up to size 400 or 600 rather than guessing, and we can check the flow curves against your demand. The automatic drain on this model suits unmanned or hard-to-reach installations; choose manual drain if an operator is on site and you want positive control, or the default differential-pressure drain otherwise. The 40 um element is standard; specify W for the 5 um grade where finer pre-filtration is needed.
PT is the standard thread on this code; G (BSPP) and NPT versions are catalogue options you can order instead. A mounting bracket is included on this code, and flow is published as curves, not a single rated figure - ask us to confirm sizing against the application 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 filter flow as performance curves, not as a single rated number, so we do not quote a figure here. Send us your line pressure and air demand and we will confirm the flow data from the datasheet for this exact model on request.
The A in the code means the bowl drains itself automatically, which suits unmanned cells and hard-to-reach points. If an operator is on site you can order the same size 300 filter with manual drain, or take the default differential-pressure drain; the thread (PT, G or NPT) and the 5 um W element option are also orderable choices.
