The AirTAC AirTAC GFR600-25 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 PT1" 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 GFR600-25 is a filter regulator: one body that removes water and particulate from compressed air and sets downstream pressure, so a single 1 in ported unit does both jobs at the head of a supply line. This 600-size configuration is fitted with the standard 40 um filter element and a differential-pressure drain that bleeds collected condensate automatically as flow passes through, with no manual draining routine to remember. Regulation is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, read on the fitted external round gauge scaled in psi. The bowl on this size is aluminium alloy, and the unit is supplied without a mounting bracket; maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with a 5 um element (code W), automatic or manual drain, a square embedded gauge or a round external gauge in MPa, psi or bar scale, G or NPT thread, and with or without a bracket. We do not quote a single rated flow figure because AirTAC publishes flow as curves; ask us and we will confirm the datasheet figures for your application before you order.

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.

At the head of a paint-line air drop, the GFR600-25 removes water and pipe scale from the shop supply and holds a steady regulated pressure to the spray-booth circuits, with the differential-pressure drain clearing condensate as air passes through.
On a machining-centre air main, this 1 in filter regulator conditions the supply feeding pallet-clamp and tool-changer circuits, giving the maintenance team a psi-scaled round gauge to set and verify setpoint at the drop.
Feeding the valve manifold that drives conveyor stops, gates and pushers on a bottling line, the unit filters the compressed air and regulates it to the pressure the cylinder bank was designed around, with the aluminium alloy bowl suited to the 600-size flow.
Start with the port step: this is the 600 size with a 1 in PT thread, the largest in the GFR range, so choose it when the line demand sits above what 1/2 in and 3/4 in units are sized for - and confirm that against the flow curves with us before ordering, since AirTAC publishes flow as curves rather than a single rating. Next, pick the drain: this unit uses the differential-pressure drain (the default), while automatic (code A) and manual (code M) versions are available if your maintenance routine prefers them. Filtration is the standard 40 um element; specify the W option only if the application needs 5 um. The gauge here is the external round type in psi scale; square embedded gauges and MPa or bar scales are the other decodable choices. Thread is PT as standard - G (BSPP) and NPT are catalogue options to order - and this configuration omits the mounting bracket (code J), so order a bracketed variant if you need panel fixing.
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, not as a single rated figure, so we do not quote a number here. Tell us your line demand and operating pressure and we will confirm the datasheet flow figures for this 1 in unit against your application before you order.
This configuration has the differential-pressure drain (the default): condensate collected in the bowl is discharged automatically as air flows through, with no operator action. If you prefer, the same 600-size unit can be ordered with an automatic drain (code A) or a manual drain (code M); note the regulation range differs by drain type, with manual-drain versions adjusting from 0.05 MPa and this differential-pressure version from 0.15 MPa (20-130 psi).
