The AirTAC GFR600C20LC1WT AirTAC Filter Regulator NPT3/4 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 GFR600C20LC1WT is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 unit is built for 3/4 in NPT ports, carries the 5 um filter element (code W) in place of the 40 um standard, and clears condensate with its differential-pressure drain. It is the low-pressure (L) regulator type; the exact adjustment range for this variant is not published in the material we hold, and we confirm it from the datasheet on request. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The size-600 bowl is aluminium alloy, and this configuration includes a round MPa gauge and a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, filter grades of 40 um standard or 5 um, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so send us your application details and we will confirm the datasheet figures 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.

Feeds filtered, regulated air to the low-pressure clamping cylinders on a CNC fixture: the 5 um element protects the valve stack, the single-body layout saves panel space, and the included bracket simplifies mounting.
Conditions the air feeding spray guns in a coating booth: water and particles are drained out, pressure is held steady at the low settings the low-pressure type is built for, and the aluminium bowl suits the shop environment.
Supplies regulated low-pressure air to air knives that blow moisture off bottles or parts on a conveyor, with the differential-pressure drain clearing condensate as the compressor cycles.
The real, decodable choices start with size: 200, 300, 400 and 600 set the port step and the flow envelope, so step up a size when your line draws more air than the smaller ports pass. Flow is published as curves, not a single rating, so ask us to check the curve against your demand before ordering. Filter grade is 40 um standard or 5 um (the W code on this unit); choose 5 um where downstream valves and cylinders need finer protection. Drain is differential-pressure here, with automatic (A) and manual (M) versions available. Gauge scale is MPa, psi or bar, and thread is PT as standard with G and NPT as order options - this unit is NPT. The bracket is included on this version; J-coded versions omit it.
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 as curves, not as a single rated number, so we do not quote a figure here. Send us your required flow and working pressure and we will confirm the datasheet curve for this 3/4 in NPT unit before you order.
It marks the low-pressure regulator type. The exact adjustment range for this variant is not published in our current data, so we confirm it on request rather than quoting a figure. Everything else in the code decodes normally: 5 um filter element, differential-pressure drain, round MPa gauge, NPT thread and included bracket.
