The AirTAC GFR600C20JC1WT AirTAC Filter Regulator NPT3/4, 5 um 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 GFR600C20JC1WT is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration carries a 3/4 in NPT port, a fine 5 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an aluminium alloy bowl suited to the largest frame in the series. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the optional external round gauge with MPa scale is fitted so downstream pressure can be read and set directly. No 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 port sizes from 1/8 in to 1 in, a choice of 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

Point-of-use conditioning for a machining centre's pneumatic clamps and tool-change cylinders: the 5 um element strips water and fine particulate from the shop-air drop, and the regulator holds a steady set pressure so clamping force stays repeatable across the shift.
Filtered, regulated air for the diverters, pushers and seal cylinders on a carton packaging conveyor. The differential-pressure drain keeps condensate moving out of the aluminium bowl without operator attention, and the round MPa gauge lets the line technician verify set pressure at a glance.
Clean, regulated pilot supply for pneumatically actuated process valves on a plant skid. The 3/4 in NPT port matches typical skid piping, the 5 um grade protects positioner and pilot internals, and the fitted gauge documents the pilot pressure the control loop depends on.
Size 600 with a 3/4 in NPT port sits at the top of the GFR range, so step up to it when your line's flow demand outgrows a 1/2 in unit - and ask us to check the published flow curve against your consumption, since no single rated figure is quoted. Drain choice matters: this unit uses the differential-pressure drain (no code letter); choose automatic (A) for unattended condensate purge or manual (M) where you want controlled draining and the wider 0.05-0.9 MPa adjustment range. The 5 um element (code W) is the finer option over the 40 um standard - keep 40 um for general shop air and specify 5 um where downstream equipment needs cleaner air. The fitted round gauge reads in MPa; psi and bar scales are also available. Thread: PT is the AirTAC standard; this unit is ordered with NPT, and G (BSPP) is the other catalogue option. Brackets are optional - this configuration omits one.
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 GFR flow as curves rather than a single rated figure, so we do not quote a l/min or SCFM number. Tell us your operating pressure and air consumption and we will confirm the flow from the datasheet curve for this exact model before you order.
PT is the standard thread on the GFR series, but G (BSPP) and NPT are catalogue order options. The trailing T in GFR600C20JC1WT specifies the NPT 3/4 in port, which suits US piping. It is a specification choice made at ordering, not a stock or delivery promise.
