The AirTAC GFR600C20C2TK AirTAC Filter Regulator NPT3/4 with Gauge 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 GFR600C20C2TK is a size 600 filter regulator that removes water and particulate from compressed air and holds downstream pressure in one body. This configuration has a 3/4 in NPT port, 40 um standard filtration, a differential-pressure drain that bleeds condensate automatically whenever the pressure drop across the element is high enough, a fitted round gauge reading in psi, a reverse/check valve, and a mounting bracket. The size 600 bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um (W) filtration, embedded square or external round gauges with MPa, psi or bar scales, PT (standard), G or NPT threads, and bracket options. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet 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.

Hung on the main drop feeding a packaging hall, the GFR600C20C2TK strips water and pipe scale from the compressed air and holds a steady regulated pressure to the hall's distribution manifold, with the psi gauge giving operators a local reading at the drop.
On a bottling or food line where conveyor stoppers, pushers and diverters run off plant air, this filter regulator cleans the supply and keeps actuator pressure stable so cylinders cycle consistently shift after shift; the reverse/check valve holds the setting if upstream supply dips.
Feeding chip conveyors, clamping fixtures and air blast nozzles around a CNC cell, this unit protects the peripherals from condensate and particulate at 40 um and lets the machinist set and read the working pressure in psi right at the machine.
Step up through sizes 200, 300, 400 and 600 to match the port and the flow your line needs; this unit is the 600 frame with a 3/4 in NPT thread. Where a bowl is fitted you choose the drain: differential-pressure (this unit, self-bleeding on pressure drop), automatic, or manual for periodic draining. Filtration is 40 um standard or 5 um with the W code if downstream equipment needs finer protection. Gauges: an embedded square gauge is standard and an external round gauge is optional, with MPa, psi or bar scales - this unit carries a round gauge reading psi. Thread is PT as standard with G and NPT as order options; this one is NPT. A mounting bracket is included, and the K code adds a reverse/check valve.
One honest note on sizing: AirTAC publishes flow as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the datasheet curve and sizing 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 GFR600 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and the flow your equipment needs and we will confirm the datasheet curve and check the sizing for you on request.
The blank drain position on this code selects the differential-pressure drain, which automatically bleeds collected condensate whenever the pressure drop across the filter element rises - no timer or manual draining needed. The C2 code selects the optional external round gauge with a psi scale; the embedded square gauge is the standard fitting and MPa or bar scales are also available.
