The AirTAC AirTAC GFR600-20 Filter Regulator PT3/4, 5 um, psi gauge is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" 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 GFR600-20 is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single 3/4 in body. This configuration carries the 5 um element (code W) for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, an external round gauge reading in psi, and a built-in reverse/check valve that holds the downstream setting when upstream supply is lost. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and a working temperature range of -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and each size can be ordered with a different drain type, filter grade, gauge style and scale, thread option (PT standard, G or NPT to order) and check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Mounted at the 3/4 in take-off feeding a packaging hall's distribution header, it strips water and fine particulate from the main supply and holds a steady regulated pressure to the downstream drops. The check valve keeps the setting during compressor cycling, and the differential-pressure drain clears condensate as flow varies through the shift.
On a pneumatic press or clamp station fed from a shared header, this unit filters the incoming air to 5 um and regulates the working pressure the cylinders and valves actually see. The psi gauge gives the setter a direct local reading, and the check valve holds the circuit's pressure if the upstream supply is interrupted mid-cycle.
Fitted where a conveyor line's air cylinders, gate diverters and blow-off nozzles branch off the main ring main, it delivers clean, regulated air at the point of use. The 5 um element protects the directional valves and cylinders from fine contamination, and the differential-pressure drain keeps moisture out of the branch without daily manual draining.
Step up or down in size (200/300/400/600) to match the port and flow path your line needs; this unit is the 600 size on a PT3/4 thread, with G or NPT available as order options. Choose the drain to suit access: differential-pressure (this unit) drains itself with flow, automatic drains on a cycle, and manual suits attended installations. Pick the 40 um standard element for general protection or the 5 um grade (this unit) where finer filtration matters, and select the gauge style and scale - embedded square or external round, in MPa, psi or bar; this unit has an external round psi gauge. The K code adds a reverse/check valve, and a bracket is included.
One honest note on sizing: AirTAC publishes flow as curves, not a single rated number, so we do not quote a flow figure here. Send us your required flow and pressure and we will confirm against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so we do not state a flow number here. Tell us your required flow and working pressure and we will confirm the sizing against the datasheet for your application before you order.
The W in the code GFR60020C2WK specifies the 5 um filter element instead of the 40 um standard grade, giving finer protection for downstream valves and cylinders. The K specifies a built-in reverse/check valve, which holds the regulated downstream pressure if the upstream supply drops. Both are standard catalogue options on the GFR family.
