Airtac GF Filter GF300C10MJ
The AirTAC Airtac GF Filter GF300C10MJ 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 GF300C10MJ
The AirTAC GF300C10MJ is a G-series air filter only: it strips water and particulate from compressed air - no regulation, no lubrication. This size 300 configuration has PT3/8 ports, the standard 40 um element and a manual drain, and the J suffix means it is supplied without a mounting bracket, keeping the body compact where it will be piped directly into a manifold or existing prep stack. With a manual drain the inlet pressure range is 0-0.9 MPa (0-130 psi).
This is a genuine AirTAC part. GF filters come in sizes 200, 300, 400 and 600, with a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) elements, and PT thread as standard with G (BSPP) and NPT catalogue options. Flow is published as curves rather than a single rating, so we confirm datasheet and sizing 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 GF300C10MJ
| 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 GF300C10MJ Is Used
Machine-built prep stacks
Dropped straight into a builder's existing filter-regulator-lubricator stack on CNC or assembly machinery, adding filtration on the 3/8" inlet without needing a separate bracket.
Truck and trailer air prep bays
A compact filter on 3/8" airline feeds in a commercial-vehicle service bay, keeping moisture and debris out of pneumatic test rigs and tyre-cage circuits, drained by hand between jobs.
Pneumatic press panel plumbing
Mounted directly on the air-prep panel of a pneumatic press, filtering the 3/8" supply to the counterbalance and clamping circuits where the manifold itself carries the mounting.
Is the Airtac GF Filter GF300C10MJ the Right Filter?
Size the unit by demand: this 300 frame carries 3/8" ports; move to 200 for smaller circuits or 400/600 for higher flow. Drain style is the practical choice: manual here, automatic (A) or differential-pressure (blank) where unattended drainage matters. Element is the standard 40 um for general plant air; add the W suffix for 5 um fine filtration. PT is the standard thread - order G or NPT variants if your installation needs them - and pick this J version when a bracket is not required.
Because flow appears only as curves in the catalogue, ask us to confirm sizing from the datasheet for 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 GF300C10MJ FAQ
No single rated number is published - AirTAC provides flow as curves. Send us your operating pressure and air demand and we will confirm the correct size and the datasheet flow information on request before you order.
Functionally they are identical: both are size 300, PT3/8, manual-drain filters with the 40 um element. The J suffix simply means no mounting bracket is supplied - choose this when the filter is panel- or manifold-mounted, and the version without J when you want the bracket included.
