The AirTAC GFR600C25LF2TK AirTAC Filter Regulator 1 in NPT 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 GFR600C25LF2TK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size-600 unit carries a 1 in NPT port for high-flow lines, filters to the standard 40 um grade, and drains condensate by differential pressure, so the bowl purges itself as the pressure differential across the element builds. It is the low-pressure (L) type, fitted with the embedded square gauge scaled in psi, a reverse/check valve (K) to hold downstream pressure when the supply drops, and a mounting bracket. At size 600 the bowl is aluminium alloy, and the maximum working pressure is 1.0 MPa (145 psi) with a -5 to 70 C (non-freezing) temperature range.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um (W) filter grade option, gauge scale options, G/NPT thread variants and bracket choices. Flow figures are 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.

On a glass plant's forming-section air ring main, a 1 in NPT filter regulator conditions the supply feeding mould-cooling and machine-actuation take-offs, with the check valve holding downstream pressure if the main dips.
At the inlet of a weld-cell valve manifold on an automotive body line, the unit strips water and 40 um particulate before directional valves and cylinders, and the low-pressure type suits circuits regulated well below full line pressure.
On a bottling hall's conveyor air-blow cleaning circuit, the regulator holds a gentle, stable pressure for nozzle bars while the 40 um element and differential-pressure drain keep rust and condensate out of the nozzles.
The real choices on this family are decodable from the code. Step size (200/300/400/600) and port (here 1 in NPT) against the flow your line needs; choose drain type - differential-pressure as fitted here, automatic (A) for unattended purge, or manual (M) where you want hands-on control; pick filter grade 40 um standard or 5 um (W) for finer protection; choose gauge scale MPa, psi or bar and square embedded versus optional external round; order PT (standard), G or NPT thread; and decide on the bracket. The L code marks this as the low-pressure type, and the K code means the reverse/check valve is fitted.
One honest note before you order: AirTAC publishes flow as curves, not a single rated figure, so we cannot quote you a rated flow number here. Tell us your line conditions and we will confirm the sizing against the datasheet on request before you commit.
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 this family as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number here. Send us your line pressure, port size and demand, and we will confirm the sizing against the datasheet on request before you order.
L marks the low-pressure regulator type, chosen where the circuit runs well below full line pressure (the exact adjustment range is not published in our material - confirm on request). K means a reverse/check valve is fitted, holding downstream pressure if the supply drops. The embedded square gauge on this code is scaled in psi; MPa and bar scales and an external round gauge are available as order options.
