The AirTAC GFR600C20JC3WT AirTAC Filter Regulator 3/4 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 GFR600C20JC3WT is a size 600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration is built around a 3/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and the fitted round gauge reads in bar so you can set and monitor the working pressure at a glance. Because this is the 600 size, the bowl is aluminium alloy, and the unit ships without a mounting bracket.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in up to 1 in. Across the family you can order different filter grades (40 um standard, 5 um optional), drain types, gauge styles and scales, and thread variants, with or without a bracket. We do not quote a single rated flow figure for this unit because the catalogue publishes flow only as curves - ask us and we will confirm the datasheet and sizing figures for your application 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.

Installed at a 3/4 in plant-air drop, the unit filters water and scale from the header supply and holds a steady regulated pressure to the cells below, with the bar gauge giving operators a visible setpoint.
Packaging machinery with cylinders, air blasts and vacuum assist runs best on clean, stable air; this filter regulator conditions the 3/4 in supply feeding the line's valve manifolds and actuators.
On a skid of air-operated valves or a large process actuator, the 5 um element protects seat and seal surfaces from particulates while the regulator keeps actuator pressure within its rated band.
Size 600 with a 3/4 in NPT port is the largest step in the GFR range, so start there when your line volume points to a 3/4 in connection - and step down to 300 or 400 if your flow sits comfortably lower. On filtration, this unit carries the 5 um element (code W); if your application tolerates coarser air, the 40 um standard grade is the alternative. The differential-pressure drain is the default and suits most continuous-duty installations; automatic and manual drains are available elsewhere in the family. The round bar gauge is fitted here; embedded square gauges and MPa or psi scales are the other catalogue choices. NPT is the ordered thread option on this code (PT is the standard thread; G/BSPP is also available), and the J code means no mounting bracket - add one if the unit will not be piped-supported. Flow for this family is published as curves rather than 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 family as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, downstream pressure target and approximate air demand, and we will confirm the flow and sizing data from the datasheet for your application on request.
The W code in GFR600C20JC3WT selects the 5 um element, the finer of the two catalogue grades (40 um is standard) - a good choice where valves, cylinders or instruments are sensitive to fine particulates. Condensate handling is by the differential-pressure drain, the default option, which discharges collected water automatically as the pressure differential across the element builds.
