The AirTAC GFR600C25MNT AirTAC Filter Regulator 1 in NPT, Manual Drain is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR600C25MNT is an AirTAC GFR-series filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air and holds a steady downstream pressure, with no lubricator in this family. This 600-size unit is specified with a 1 in NPT port, a manual drain (code M), and the standard 40 um filter element. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi) with manual drain, against a maximum working (inlet) pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing. At size 600 the bowl is aluminium alloy. No gauge is fitted on this variant (code N) and no reverse/check valve is included; a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600, with port sizes stepping from 1/8 in up to 1 in, a choice of 40 um (standard) or 5 um (code W) filtration, differential-pressure, automatic or manual drains, gauge options, and PT (standard), G or NPT threads to order. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 0.15 - 0.9 MPa (20 - 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.

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.

Point-of-use water and particulate removal with regulated pressure feeding spray guns and air-assisted equipment on a paint line, where clean, steady air protects finish quality.
Filtering and regulating the compressed air supply to quarter-turn pneumatic actuators on a treatment-plant skid, keeping actuator supply pressure stable and free of condensate carryover.
Conditioning and regulating air to the pick-and-place and clamp cylinders on a packaging cartoning line, where a manual-drain bowl suits a station checked each shift.
Work from the port step first: the 600 size with a 1 in port is the largest step in the GFR range (200/300/400/600), so match it to your line size and the flow curve rather than to a single rating. Choose the drain next: this unit is manual (M), meaning the bowl is drained by hand, while automatic (A) and differential-pressure (blank) drains are available in the same family. Filtration is 40 um standard; specify the W option if you need 5 um. Gauge, scale and thread are order choices: this variant ships without a gauge (N), and PT is the standard thread with G and NPT as catalogue options - this unit is the NPT version. A bracket is included. Because flow is published as curves, not 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, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, downstream set pressure and expected air demand, and we will confirm the sizing against the datasheet on request before you order.
The M code means condensate collected in the aluminium alloy bowl is drained by hand rather than automatically, so the bowl should be checked and drained as part of routine maintenance. Note that with a manual drain the regulator adjustment range is 0.05-0.9 MPa (7-130 psi); automatic and differential-pressure drain variants are available in the same family if you prefer unattended drainage.
