The AirTAC GFR600C25MLJF1TK 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 GFR600C25MLJF1TK is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This 600-size unit is threaded 1 in NPT and carries the standard 40 um filter element with a manual drain bowl in aluminium alloy. The regulator is the low-pressure type, selected for circuits that hold a reduced set pressure, and an embedded square gauge scaled in MPa is fitted. A reverse (check) valve is included and no mounting bracket is supplied with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of drain (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scale choices and G/NPT thread options. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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.

| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Clean, regulated air ahead of the directional valves on a stamping or forming press, with the low-pressure regulator holding the circuit at a reduced set pressure.
Point-of-use air preparation for carton-sealer and case-packer cylinders, removing water and pipe scale before it reaches the valve bank.
Filtered, regulated supply to pneumatic clamps and workholding fixtures on a CNC cell, with the fitted check valve protecting the downstream circuit.
Size and port: 600 is the largest G-series size, here with a 1 in NPT port; step down through 200/300/400 when your flow curve allows a smaller port. Drain: this unit is manual drain, so the bowl is drained by hand at intervals; automatic and differential-pressure drains are available if you prefer unattended draining. Filter grade: the 40 um element is standard; choose code W for 5 um where finer particulate removal is needed. Gauge: the embedded square gauge is scaled in MPa; psi or bar scales and an external round gauge can be ordered. Thread: PT is the AirTAC standard and G (BSPP) and NPT are order options - this unit is NPT. No mounting bracket is supplied (code J).
Flow for the GFR series is published as curves, not a single rating, so send us your application details 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 flow for the GFR series as curves rather than a single rated figure, so no rated flow number is quoted here. Send us your line pressure, set pressure and downstream demand and we will confirm the sizing from the datasheet on request.
The M in this code selects a manual drain: the bowl is drained by hand at intervals. If the installation runs unattended, the same unit can be ordered with an automatic or differential-pressure drain instead. The filter element stays 40 um as standard, or 5 um with code W.
