The AirTAC GFR60025ALC1T 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 GFR60025ALC1T is a size-600 GFR filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air at a 40 um grade, then regulates downstream pressure, with an automatic drain discharging collected condensate from the bowl without manual attention. This configuration is fitted with 1 in NPT ports, the low-pressure regulator type, a round pressure gauge reading in MPa, and an aluminium alloy bowl. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with manual, automatic or differential-pressure draining, a 5 um (W) filter grade instead of the 40 um standard, square or round gauges with MPa, psi or bar scales, a reverse/check valve, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and 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. 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. |

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 at the head of a large packaging-hall air drop, this unit cleans the shop supply of water and scale and holds a steady regulated pressure to the hall's distribution legs, while the automatic drain keeps the aluminium bowl clear of condensate on a line nobody visits daily.
Mounted at the machine inlet on a CNC machining centre, it filters incoming compressed air before it reaches tool-clamp and actuator circuits and regulates the supply to the machine's own pressure requirement, with the round MPa gauge giving the setter a direct reading at the panel.
Fitted where a conveyor line branches off the main header, it removes moisture and particulate before the diverters and stopper cylinders and regulates their supply pressure, the 1 in NPT ports matching the branch line and the automatic drain suiting an unmanned section of the plant.
Start with the port step: size 600 with 1 in ports is the largest GFR frame, so match it against the air demand of the circuit - if your consumption sits below what a 1 in line carries, a smaller 200/300/400 size may be the more economical choice. Choose the drain to suit access: automatic (this unit) for installations where nobody passes by to drain, manual for supervised points, or the differential-pressure default. Filter grade is 40 um as standard; specify 5 um (code W) only where finer particulate control is genuinely needed. Gauge options are the embedded square gauge or an external round gauge (fitted here) with MPa, psi or bar scales. Thread is PT as the AirTAC standard, with G (BSPP) and NPT as order options - this unit carries NPT. A mounting bracket is included; the J suffix removes it.
Two honest routing notes: flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. This is the low-pressure type (code L); its exact regulation range is not published in the material we hold, so confirm the regulated band with us before ordering if your circuit runs at reduced pressure.
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 rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your operating conditions and required consumption and we will confirm the flow from the datasheet curves for your application before you order.
The L in the code makes this the low-pressure regulator type, intended for circuits regulated below the standard unit's band; its exact regulation range is not published in our material, so confirm it with us before ordering. The A gives an automatic drain, which discharges condensate from the bowl without manual intervention - the alternative codes are M (manual) and blank (differential-pressure). The C1 adds a round gauge reading in MPa; psi and bar scales are available.
