The AirTAC GFR600-25T AirTAC Filter Regulator 1 in NPT 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-25T is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration is fitted with a 1 in NPT port, a manual drain bowl in aluminium alloy, a fine 5 um filter element (the W grade, tighter than the 40 um standard), an embedded square gauge scaled in bar, and no mounting bracket. The manual drain means an operator opens the bowl drain to expel collected condensate, which suits installations checked on a regular service round.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Rated flow for this unit is published as curves rather than a single figure, so ask us and we will confirm the datasheet and sizing figures on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Installed at a 1 in header take-off feeding a production hall, it cleans water and scale from the plant supply and holds a steady regulated pressure for the downstream distribution legs.
Feeding the air lines of machining centres and their pneumatic clamps, the 5 um element protects spool valves and chucks from fine particulate while the regulator keeps clamp pressure consistent.
On the air feed to a blast or coating booth, water and 5 um-level dirt are stripped out before the media or coating equipment, and the manual drain is emptied during the end-of-shift check.
Step up or down through the GFR sizes (200, 300, 400, 600) to match the port and the flow your line needs; this 600 unit carries the 1 in port at the top of the range. Drain type is a real choice: manual (this unit) for attended service rounds, automatic for unattended condensate removal, or the differential-pressure default. Filter grade is 40 um standard or 5 um with the W code - this unit carries the 5 um element for finer protection. Gauge scale is selectable (MPa, psi or bar), thread is PT as standard with G and NPT as orderable options (this unit is NPT), and a bracket can be added or omitted (omitted here). Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the datasheet flow curves and check the sizing for you on request.
The M code in GFR600-25MJF3WT specifies a manual drain: an operator opens the bowl drain to release collected condensate, which suits installations visited on a regular service round. The automatic-drain option expels condensate on its own for unattended lines, and the differential-pressure drain is the catalogue default.
