AirTAC GF300-10 Filter (GF30010AT)
The AirTAC AirTAC GF300-10 Filter (GF30010AT) 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 PT3/8" 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.

About the AirTAC GF300-10 Filter (GF30010AT)
The AirTAC GF30010AT is a G-series compressed-air filter: it removes water and particulate from the air line and does nothing else - there is no pressure regulation and no lubrication in this unit. This configuration is size 300 with a 3/8 in PT port, a 40 um standard filter element, and an automatic drain that ejects collected condensate from the PC bowl without anyone opening it, which suits unattended installations. Maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GF family is offered in sizes 200, 300, 400 and 600, with automatic, manual or differential-pressure drains, a 5 um element option (suffix W), and G (BSPP) or NPT thread options alongside the standard PT port. Flow data is published as curves rather than a single rating - we 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.
Model Code: AirTAC GF300-10 Filter (GF30010AT)
| GF300 | G-series air filter, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". 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. |
| T | NPT 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 GF300-10 Filter (GF30010AT) Is Used
CNC machine air supply
Installed on the compressed-air feed to a CNC machining centre, the GF30010AT removes water and particles before the air reaches tool-clamp and pallet-change actuators, with the automatic drain keeping the bowl clear during unattended shifts.
Pneumatic impact-tool loop
Fitted ahead of the drop lines feeding impact wrenches and grinders on an assembly floor, it strips condensate carried over from the compressor so the tools run on drier air; the 3/8 in PT port suits a workshop distribution line.
Truck air-prep feed
Placed in the air preparation line of a commercial-vehicle service bay, it filters the shop air before it reaches brake-testing and tyre equipment, with the automatic drain coping between jobs without manual blowdown.
Is the AirTAC GF300-10 Filter (GF30010AT) the Right Filter?
Size 300 with a 3/8 in PT port is the mid step in the GF range; step up to 400 or 600 for larger ports and higher flow, or down to 200 for compact lines. The automatic drain on this AT version is the right choice where the filter sits where nobody regularly walks past; choose manual drain for supervised positions or differential-pressure drain for the lowest-cost default. The standard element is 40 um; add W to the code for the 5 um grade if downstream equipment needs finer particle removal.
Thread is standard PT; G (BSPP) and NPT versions are catalogue options to order. Bracket is included on this version (J code deletes it). Flow is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GF300-10 Filter (GF30010AT) FAQ
AirTAC publishes filter flow as curves rather than one rated figure, so there is no single number we can honestly quote. Tell us your line conditions and we will confirm the relevant flow data from the GF300 datasheet on request before you order.
This AT version carries an automatic drain, so collected condensate is expelled without an operator. The GF300 is also available with manual drain or the differential-pressure default - pick automatic for out-of-the-way or unattended positions where manual blowdown would be forgotten.
