The AirTAC GFR600C25MLJF2TK 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 GFR600C25MLJF2TK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates the pressure delivered downstream. This configuration is built around a 1 in NPT port, a manual drain on the aluminium alloy bowl, the standard 40 um filter element, and the low-pressure regulator type, selected where the required setpoint sits below what the standard type covers. An embedded square gauge with a psi scale is fitted, a reverse (check) valve is included, and no mounting bracket is supplied. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200 to 600 with ports from 1/8 in to 1 in, and options for thread (PT standard; G and NPT to order), drain type, 5 um filtration (code W), gauge style and scale, and bracket. AirTAC publishes flow for this series as curves rather than a single rated figure, so we confirm flow and other datasheet figures on request before you order.

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.

Filter and regulate the supply feeding carton-sealing and wrap cylinders on a packaging line, using the manual drain during scheduled stops to clear water collected in the aluminium bowl.
Feed pilot solenoids and positioners on an actuated valve manifold, where the 40 um element keeps the pilot air clean and the psi-scale square gauge gives operators a readable setpoint.
Supply the pneumatic cylinders that index, stop and clamp product on a conveyor line; the fitted check valve blocks backflow if the upstream supply dips.
The real choices on this series: size 200/300/400/600 sets the port and the flow capacity, so step up a size when demand outgrows the smaller ports. Drain type is manual on this unit; automatic and differential-pressure drains are other codes in the same series. Filter grade is 40 um standard, with 5 um available as code W. The gauge is the embedded square type here, with an external round gauge optional and MPa, psi or bar scales. Thread: PT is the standard and G (BSPP) and NPT are order options - this unit is NPT. Bracket: J codes omit it, as here. The low-pressure regulator type (L) is chosen where setpoints sit below the standard band; its exact range is not published, so confirm it with us. 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 GFR600 series as curves rather than a single rated figure, so we do not quote a number here. Send us your inlet pressure and air demand and we will confirm the sizing against the datasheet on request.
The M in the code specifies a manual drain: water collected in the aluminium alloy bowl is released by operating the drain when you choose, which suits lines with scheduled maintenance stops. Automatic (code A) and differential-pressure (blank) drains are available as other codes in the same series.
