The AirTAC GFR600C25AJF2K AirTAC Filter Regulator 1 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 AirTAC GFR600C25AJF2K is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit is fitted with a 1 in PT port, the standard 40 um filter element, and an automatic drain that expels collected condensate without anyone opening the bowl. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, read on the embedded square gauge supplied in the psi scale. A reverse/check valve is fitted to hold the downstream setting if upstream supply is lost, and the aluminium alloy bowl suits this large frame. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as standard and G or NPT threads as order options, manual or differential-pressure drains, a 5 um element (code W), gauge scales in MPa, psi or bar, and bracket variants. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Feeding spray-booth and paint-line air drops where water and pipe scale must be stripped out and the atomising pressure held steady at the gun manifold, with the automatic drain handling condensate between shifts.
Conditioning the shop-air feed to a machining center's pneumatic tool changer and clamping circuit, filtering particulate and regulating a stable pressure so clamps and tool-release cylinders behave consistently.
Supplying the cylinder and air-blow circuits on a bottling or canning conveyor run, where the check valve holds the set pressure through upstream dips and the automatic drain copes with a humid plant air supply.
Size 600 with a 1 in PT port is the largest step in the GFR range, so start there when the line diameter and the air demand of the machines downstream call for the top of the family. Choose the drain to match attendance: the automatic drain on this code suits unattended or hard-to-reach installations, while manual and differential-pressure drains are available on other codes. The 40 um element is the standard grade; specify the 5 um W variant if finer particulate removal is needed. The square gauge here reads in psi; MPa and bar scales are alternatives, and an external round gauge is optional. PT is the standard thread, with G and NPT available to order; brackets are optional on other codes but not fitted here.
Because flow is published as curves and not as a single rated figure, we do not quote a number here. Ask us to confirm sizing from the datasheet against your actual air demand 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 state a number here. Tell us your line size and the air demand of the equipment downstream, and we will confirm the flow and other datasheet figures for this 1 in PT unit on request before you order.
The A in the code selects the automatic drain: condensate collected in the aluminium alloy bowl is expelled on its own, which suits installations that are not checked daily. The K adds a reverse/check valve, so if the upstream supply drops, the regulated downstream pressure is held instead of bleeding back. Both are decode choices - manual and differential-pressure drains, and units without the check valve, exist in the same family.
