The AirTAC GFR600-25ALC1TK AirTAC Filter Regulator NPT1 Low Pressure 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 automatic 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 GFR600-25ALC1TK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one body. This 600-size unit is built with a 1 in NPT port, an automatic drain that ejects collected condensate without manual attention, and the standard 40 um filter element. It is the low-pressure type, so its regulation range differs from the standard unit - the exact figures are on the datasheet, which we confirm on request. A round MPa gauge is fitted, a reverse/check valve is included, and the aluminium alloy bowl suits this largest frame. 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 family spans sizes 200 to 600 with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of automatic, manual or differential-pressure drain, 40 um or 5 um (W) filtration, and square or round gauges with MPa, psi or bar scales. Flow for this size is published as curves rather than a single rated figure; ask us to confirm the datasheet figures against 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |

| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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.

Installed on the 1 in main air feed of a bottling hall, it strips water and particulate from the plant air and holds a steady low-pressure setting for the drop network serving cappers, labelers and check-weigh actuators, while the automatic drain clears condensate on its own.
Mounted upstream of a large pneumatic press or clamp-cylinder manifold, it delivers clean, regulated air to the cylinders; the low-pressure type suits circuits run below standard plant pressure, and the fitted gauge gives the operator a direct reading of the set point.
Feeding the stopper, gate and divert cylinders along a packaging conveyor line, it keeps the actuation air filtered and held at the set pressure; the reverse/check valve holds the downstream circuit if upstream supply dips, and the automatic drain suits an unattended line.
Size and port step up with air demand: the 200, 300, 400 and 600 frames carry ports from 1/8 in to 1 in, and this unit sits at the top of the range with a 1 in NPT port - match the frame to the demand of the line, then confirm the match against the published flow curves with us before ordering. The real, decodable choices on this family are: drain type (automatic as fitted here, or manual, or the differential-pressure default), filter grade (40 um standard, 5 um with code W), gauge (embedded square as standard, external round optional, scales MPa, psi or bar), thread (PT standard; G and NPT are order options) and mounting bracket. This unit is the low-pressure type (L), so its regulation range should be quoted from the datasheet rather than from the standard-type figures. Flow is published as curves, not a single rating - ask us to confirm sizing against your application.
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 this family as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet flow figures for this 600-size, 1 in NPT unit against your demand before you order.
The A in the code fits the automatic drain, which ejects collected condensate without anyone opening the bowl - useful on unattended or high-humidity installations. The GFR family is also available with a manual drain or the differential-pressure default, and the bowl on this 600 size is aluminium alloy.
