The AirTAC GFR600-25 AirTAC Filter Regulator 1 in PT 5 um Manual Drain 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 GFR600-25 is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This 600-size unit is configured with a 1 in PT (BSPT-type standard) port, a 5 um filter element (the finer of the two catalogue grades), a manual drain on the bowl, an embedded square gauge reading in psi, and a reverse/check valve fitted. The manual drain means an operator opens the drain at the bottom of the bowl to expel collected condensate, which suits installations visited on a routine round. The aluminium alloy bowl on this 600 size gives a robust metal pressure vessel where a polycarbonate bowl is not wanted.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, PT / G / NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um elements, gauge scales in MPa, psi or bar, and an optional reverse/check valve. A maximum working pressure of 1.0 MPa (145 psi), a regulation range of 0.05-0.9 MPa (7-130 psi) for this manual-drain version, and a temperature range of -5 to 70 C (non-freezing) are the published figures. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Clean, regulated air to the main cylinder and clutch valve circuit of a stamping press, with the check valve holding the set pressure if the shop supply dips mid-stroke.
Conditioning the air feeding conveyor stopper cylinders, gating actuators and bagger clamps on a high-cycle packaging line, where the 5 um element protects the valve spools.
A 1 in main-line air drop serving an assembly cell, filtering water and pipe scale out of the plant supply and setting a stable working pressure for the cell's tools and fixtures.
Size 600 with a 1 in port is the largest step in the GFR range, so start here when the pipeline and the air demand are at the top of the family's span - and step down to 200/300/400 if your porting and flow curve allow. Choose the drain with the maintenance pattern in mind: manual drain (this unit) needs someone to bleed the bowl, automatic drain bleeds itself, and the differential-pressure default sits in between. The 5 um element (code W) is the finer choice over the 40 um standard - pick it when downstream valves, cylinders or instruments want cleaner air. The square gauge is fitted here reading psi; MPa and bar scales and an external round gauge are the other catalogue options. Thread is PT as standard, with G (BSPP) and NPT available to order; the reverse/check valve (K) holds downstream pressure if the upstream supply drops, and no mounting bracket is included on this code.
Because flow is published as curves and not a single rated figure, we cannot honestly quote one number here - send us your application's air demand and we will confirm the sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as performance curves, not as a single rated number, so we will not quote a figure that is not on the datasheet. Tell us your port size, upstream pressure and required downstream flow, and we will confirm the curve data and sizing for your application on request before you order.
The M in the code selects a manual drain: an operator opens the bowl drain to expel collected condensate, which suits lines on a regular maintenance round; automatic and differential-pressure drains are the other catalogue choices. The W selects the 5 um element instead of the 40 um standard, giving finer particulate removal for downstream valves and instruments on this same 1 in PT body.
