The AirTAC GFR600C25MC1TK AirTAC Filter Regulator NPT 1 in 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 GFR600C25MC1TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 1 in NPT port, a 40 um standard filtration element, a manual drain bowl, and a fitted check valve so downstream pressure is held if the supply drops. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the fitted round gauge reads in MPa. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and in PT, G (BSPP) or NPT thread, with a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and check-valve or low-pressure variants. 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.

Installed at the drop from a plant air main to a packaging line, it strips water and pipe scale from the supply and holds a steady regulated pressure to the line's air cylinders and valves. The check valve keeps the set pressure in place during brief supply dips.
Mounted ahead of a conveyor system's air-operated clamps and diverters, it filters the incoming air and regulates it to the pressure the clamp cylinders were designed for, protecting seals and giving repeatable clamping force. The manual drain is emptied during scheduled line checks.
Fitted on the air supply panel of a process skid, it conditions and regulates the air feeding solenoid valves and positioners, with the MPa gauge giving operators a visible set-point. The aluminium bowl and bracket mounting suit a fixed panel installation.
Size 600 with a 1 in NPT port is the largest step in the GFR range, so start there when the line and expected flow demand it, then work down to 400, 300 or 200 if the application is smaller. Drain type is a real choice: manual drain (this unit) needs someone to open the bowl drain, while automatic and differential-pressure drains discharge condensate without attention. Filtration is 40 um standard; choose the W code for 5 um where finer pre-filtration matters. Gauges can be the embedded square type or an external round gauge, in MPa, psi or bar scales, and the body can be ordered in PT, G (BSPP) or NPT thread with or without a mounting bracket. Flow for this series is published as curves, not a single rating, so 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 flow number. Tell us your line pressure, set pressure and expected air demand and we will confirm the sizing from the datasheet on request.
The M code in GFR600C25MC1TK specifies a manual drain bowl, which is emptied by hand during maintenance. GFR units can also be ordered with an automatic drain or the default differential-pressure drain, which discharge condensate without operator attention. All three share the same filtration and regulation function, with a manual-drain regulator adjusting from 0.05-0.9 MPa (7-130 psi).
