The AirTAC GFR600C25MLC2WT AirTAC Filter Regulator NPT1 Low-Pressure 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 GFR600C25MLC2WT is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This 600-size unit has a 1 in NPT port, the low-pressure regulator type, a 5 um filter element (code W), and a manual drain on the aluminium alloy bowl. A round gauge scaled in psi is fitted, the mounting bracket is included, and no reverse (check) valve is fitted.
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, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um filtration, and gauge and thread options. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. AirTAC publishes flow only as curves rather than a single rating, so we confirm flow and datasheet figures on request.

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 an automotive weld line, filtered and regulated low-pressure air feeds the clamp cylinders. The 5 um element keeps spool valves and clamp cylinders clean, the manual drain clears accumulated condensate at shift checks, and the psi gauge lets the setter read line pressure directly.
In a paint or coating booth, atomizing air to the spray guns must be clean and held at a steady low setting. This unit filters the shop air to 5 um, regulates it with the low-pressure type regulator, and the round psi gauge gives the operator a direct reading at the booth.
On a carton packaging conveyor, vacuum and gripper circuits need dry, regulated air to hold parts consistently. The 1 in NPT port suits a main drop feeding several stations, the manual-drain aluminium bowl is emptied during planned stops, and the bracket simplifies mounting at the line frame.
Size and port step up from 200 through 600 as flow demand grows; this is the 600 size with a 1 in NPT port, so match the step to your line's flow requirement - we can check the published flow curve against your application before you order. Drain type is a real choice: differential-pressure (default), automatic (A) or manual (M, as here); manual suits points where an operator drains the bowl on a schedule. Filter grade is 40 um standard or 5 um (W) for finer protection of downstream valves and cylinders - this unit carries 5 um. Gauge scale can be MPa, psi or bar, and thread is PT as standard with G (BSPP) and NPT as order options. The low-pressure (L) type has a different regulation range from the standard type; the exact range is not published, so confirm it with us 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 as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and the full datasheet figures for this model on request.
M means a manual drain: condensate collected in the aluminium alloy bowl is released by hand on a schedule you set. If you prefer unattended drainage, the same unit is available with an automatic drain (code A) or the differential-pressure drain (blank), which are the other catalogue drain choices for this family.
