The AirTAC GFR600C20ALF2WK AirTAC Filter Regulator 3/4 in PT 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 GFR600C20ALF2WK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates the pressure delivered downstream. This 600-size unit carries a 3/4 in PT port, a 5 um filter element (the finer of the two published grades), and an automatic drain that discharges collected condensate without manual attention. The regulator is the low-pressure type; its exact adjustment range is not published in the catalogue, so we confirm it on request. A square pressure gauge reading in psi is fitted, a reverse/check valve is installed, maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and on this size the metal bowl is aluminium alloy. A mounting bracket is included.
This is a genuine AirTAC part. GFR filter regulators are published in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, MPa, psi or bar gauge scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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.

Conditioning and regulating the 3/4 in air feed to a stamping or forming press, where cylinders and control valves need clean air held at a set low pressure.
Point-of-use preparation on a plant-air drop feeding case sealers, wrappers and cartoners, with the automatic drain handling condensate through long shifts.
Filtered, regulated air for a machining centre's clamping and tool-change circuits, with the 5 um element protecting the downstream pneumatic components.
The decodable choices on this series are real: step size (200/300/400/600) and port (1/8 to 1 in) against the flow your line needs; drain type - automatic as fitted here, manual, or the differential-pressure default; filter grade 40 um standard or 5 um with the W code, as on this unit; gauge scale in MPa, psi or bar; thread PT (the standard) or G/NPT as order options; and the mounting bracket. Flow for the GFR series is published as curves, not a single rating, so send us your flow and pressure conditions and we will confirm the right size 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 series as curves rather than a single rated figure, so there is no one number we can quote. Send us your required flow and working pressure and we will confirm the sizing against the datasheet curves on request.
The L code marks the low-pressure regulator type; its exact adjustment range is not published in the catalogue, so we confirm it on request. The A code is the automatic drain: the bowl discharges collected condensate on its own, so no manual draining is needed.
