The AirTAC GFR600-25 AirTAC Filter Regulator G1, 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 holds downstream pressure steady. This size 600 unit is built around a G1 (1 in) port, carries a 5 um filter element (the finer of the two published grades), a manual drain on the aluminium alloy bowl, and an embedded square gauge reading in psi. The regulating spring covers 0.05-0.9 MPa (7-130 psi), and the unit is rated for a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
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, in PT (standard), G or NPT thread, with 40 um or 5 um filtration, differential-pressure, automatic or manual drains, and square or optional external round gauges in MPa, psi or bar scales. Flow for this series is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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. |
| 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.

Feeding clean, regulated air to a machine tool's pneumatic valves and workholding clamps: the 5 um element catches fine particulate before it reaches the control valves, the regulator holds a steady setting for consistent clamping force, and the manual drain is opened during shift checks to clear collected water from the aluminium bowl.
Supplying carton-sealing and case-packing cylinders on a packaging conveyor: the regulator keeps the pressure setting stable so sealing force does not drift between cycles, while water and pipe-scale are stripped out ahead of the cylinders and drained by hand at the start of each shift.
Conditioning the air drop that feeds spray guns in a paint booth: the 5 um grade removes fine particulate that would otherwise show in the finish, the regulator holds the gun supply pressure at the set point, and the manual drain lets the operator bleed off accumulated moisture between batches.
Size and port set the capacity: the 600 frame with its G1 (1 in) port is the largest step in the GFR range, so match it against the air demand of the circuit. Drain type is a real choice - this unit has a manual drain that needs someone to open it, while automatic and differential-pressure drains are available in the same frame. Filtration is 5 um here; the standard grade is 40 um if the downstream equipment tolerates coarser air. The gauge is the embedded square type reading psi (MPa and bar scales are options), and an external round gauge can be fitted. Thread is G; PT is the standard and NPT is also an order option. A mounting bracket is not included with this code but is available. 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 application details and we will confirm the datasheet flow curve and sizing for this G1 (1 in) filter regulator before you order.
This code carries M - a manual drain you open by hand to release collected water from the bowl. The same GFR600 frame is available with automatic or differential-pressure drains if you prefer drainage without operator attention; ask us to quote the variant.
