The AirTAC GFR600C25MLC2T AirTAC Filter Regulator 1 in NPT 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 AirTAC GFR600C25MLC2T is a filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure at your setpoint. This size 600 unit is built for 1 in (NPT1) ports, carries a manual drain on its aluminium alloy bowl, and uses the 40 um standard filter element. The regulator is the low-pressure type, and the unit is supplied with an external round pressure gauge scaled in psi plus a mounting bracket.
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, PT as the standard thread and G (BSPP) or NPT as order options, a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) filter elements, and gauge or no-gauge variants. 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 the datasheet and sizing 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 0.15 - 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.

On a workshop pneumatic press, this unit filters shop-air moisture and particles out of the 1 in supply line and holds the reduced pressure feeding the press cylinder circuit, with the psi gauge giving the operator a direct read of the set pressure.
Packaging machines with carton-sealing and case-erecting cylinders need clean, regulated air at the machine header. This filter regulator conditions the main 1 in drop to the machine and its manual drain allows collected water to be bled at each shift check.
Sorting and diverting gates on conveyor lines run from air cylinders that need steady, filtered supply pressure to sequence reliably. Mounted at the line take-off with its included bracket, this unit cleans the air and regulates the circuit feeding the diverter valves.
Size and port are the first decision: GFR units step through sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, so match the size step to the air demand of the line - this unit is the largest of the range, at 1 in NPT. Drain type matters in service: manual (this unit) needs periodic bleeding by an operator, automatic drains continuously, and the differential-pressure default drains on a pressure drop. Filter grade is 40 um standard or 5 um with the W code, and gauges are available as the embedded square type or an external round gauge scaled in MPa, psi or bar. Thread is NPT here, with PT as the catalogue standard and G (BSPP) orderable. Flow is published as curves, not a single rating, so send us your supply pressure, set pressure and air demand and we will confirm sizing against the datasheet before you order.
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 GFR flow as curves, not as a single rated figure, so we do not quote a number here. Send us your supply pressure, set pressure and air demand and we will confirm the flow curve and sizing from the datasheet on request.
The M code means a manual drain: an operator opens it to discharge the water collected in the bowl, which suits installations that are visited regularly. If the unit sits in an inaccessible spot or runs unattended, order the automatic-drain variant instead; the catalogue default is the differential-pressure drain. All three drain types are order options on the same GFR600 body.
