The AirTAC GFR600C25LC1T 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 GFR600C25LC1T is a filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This size-600 unit carries a 1 in NPT port for high-capacity air lines, a 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises. The bowl on size-600 units is aluminium alloy, and the low-pressure (L) regulator type is intended for circuits held at reduced working pressure below the standard setting range. A round external pressure gauge scaled in MPa is fitted so the regulated outlet can be read and adjusted directly.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and a choice of PT, G (BSPP) or NPT threads. Other catalogue options include manual or automatic drains, a 5 um element (code W), square embedded or round external gauges in MPa, psi or bar scales, and a reverse/check valve. Rated flow for GFR units is published as curves rather than a single figure, so ask us to confirm the datasheet numbers 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.

Feeding run of pneumatic pushers and stop cylinders on a bottling or carton conveyor line, where the low-pressure regulator type holds the actuator circuit at a reduced, stable setting and the 40 um element keeps packing debris and line water out of the valves.
Supplying quarter-turn pneumatic actuators on a water-treatment or chemical skid, with the 1 in NPT port matching the plant air header, the differential-pressure drain handling condensate in a continuously pressurised header, and the MPa gauge giving operators a local setpoint readout.
Serving as the point-of-use filter regulator on a large-diameter air drop feeding an automotive assembly cell, filtering compressor carryover before it reaches air tools and fixtures while the low-pressure type regulates the cell circuit independently of the main header.
Start with the port: this unit is the 1 in NPT (T) version of the size-600 body, the largest step in the GFR range, so match it to the main-line supply of your circuit. Drain choice is a real decision: the differential-pressure drain fitted here needs no operator attention, while manual (M) and automatic (A) drains are catalogue alternatives. Filter grade is 40 um as built; specify W for the 5 um element if downstream equipment needs finer filtration. The L suffix makes this the low-pressure regulator type rather than the standard type - confirm the exact setting range with us before ordering. Gauge scale (MPa, psi or bar), thread family (PT standard, G or NPT to order) and the included mounting bracket complete the decodable choices. Because flow is published as curves and not a single rating, 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 GFR units as performance curves rather than a single rated figure, so there is no one flow number we can honestly quote. Send us your line pressure, port size and expected air demand and we will confirm the relevant curve and datasheet figures for this exact model on request before you order.
L marks the low-pressure regulator type rather than the standard type; the exact setting range for the low-pressure version is not published in the standard table, so confirm it with us for your application. This unit also carries no drain letter, which means the differential-pressure drain: condensate in the aluminium alloy bowl is expelled automatically when the pressure drop across the 40 um element reaches the discharge threshold, with no operator action needed.
