The AirTAC GFR600-25 G AirTAC Filter Regulator 1 in, 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: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is fitted with a G1 (1 in) BSPP port, a 5 um filter element (code W, finer than the 40 um standard), a manual drain on the aluminium alloy bowl, a low-pressure regulator, and an embedded square gauge scaled in psi. No reverse/check valve is fitted and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge scale options, G or NPT thread variants and optional brackets. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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)). |
| L | Low-pressure 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. |
| G | G (BSPP) 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.

Filtering and regulating the 1 in main that feeds pneumatic clamps and press cylinders on a foundry forming line, where air is cleaned to 5 um and held at a low regulated setting.
Conditioning the air feeding conveyor diverters and case-packing cylinders on a bottling line, with the embedded square psi gauge giving operators a local setpoint readout.
Supplying a low-pressure blow-off station on a plastics thermoforming line, where a manually drained aluminium bowl suits a shift-maintained cell and the 5 um element protects the nozzles.
Choose the size and port against the flow your line needs - this 600-size unit carries a 1 in G port, the largest step in the range. The 5 um element suits air prep ahead of sensitive valves and instruments; the 40 um standard element is available if finer filtration is not required. The manual drain needs an operator to bleed the bowl, unlike the automatic or differential-pressure drain options. The low-pressure regulator is intended where downstream settings sit below the standard range - the exact regulation range for the low-pressure type is not published in our data, so confirm it with us. The embedded square gauge reads in psi (MPa and bar scales are options), and G or NPT thread variants can be ordered. Because flow is published as curves rather than a single rating, 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. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the flow and datasheet figures for this 1 in unit on request.
The manual drain needs an operator to open it and bleed collected water, unlike the automatic or differential-pressure drain options that suit unattended installations. The L code also makes this a low-pressure regulator: its exact regulation range is not published in our data, so confirm the setpoint you need with us before ordering.
