The AirTAC GFR600-25ALJC2W AirTAC Filter Regulator PT1 5um Auto Drain is a genuine G-series filter regulator: water separation, 5 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 GFR600-25ALJC2W is an AirTAC GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is threaded PT1 (1 in), fitted with the 5 um element (code W) for finer filtration than the 40 um standard, and an automatic drain that discharges collected condensate without manual attention. The regulator is the low-pressure type (L); its exact adjustment range is not published, so confirm it with us if your setpoint is critical. It carries a round external gauge scaled in psi and an aluminium alloy bowl; no mounting bracket is fitted and no reverse/check valve is included. 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, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices of differential-pressure, automatic or manual, 40 um or 5 um elements, and gauge and thread options (PT standard, with G and NPT available to order). Flow for this family is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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.

On a bottling line, solenoid and pilot valves need clean, moisture-free air at a steady setpoint. The 5 um element protects valve seats from fine particulate, the automatic drain clears condensate without operator rounds, and the low-pressure regulator holds the pilot circuit at its working pressure.
A machining cell drawing air for clamps, air blasts and chuck actuation needs water and chips kept out of the circuit. This unit filters and regulates at the drop, the round psi gauge gives operators a direct pressure readout, and the 1 in PT port matches a main header feed.
Spray guns and air-driven agitators in a paint booth run at modest pressures where a standard-range regulator overshoots. The low-pressure type suits these setpoints, the 5 um grade keeps finish-ruining particles out of the air stream, and the automatic drain protects the line between shifts.
The real choices on this unit: the 600 size with its PT1 (1 in) port suits lines plumbed at 1 in - step down to the 300 or 400 sizes where the port or air demand is smaller. Drain is automatic here; manual and differential-pressure drains are the other catalogue options. The 5 um element (W) is the finer grade against the 40 um standard - choose it where downstream valves or instruments are sensitive to fine particulate. The round gauge is scaled in psi; an embedded square gauge and MPa or bar scales are the alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and this configuration has no mounting bracket. Flow is published as curves, not a single rating, so send us your demand and we will confirm sizing against the datasheet 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 GFR flow as curves rather than a single rated figure, so we do not quote a flow number for this unit. Send us your line pressure, setpoint and air demand and we will confirm the sizing from the datasheet on request before you order.
It marks the low-pressure regulator type rather than the standard one. Its exact adjustment range is not published in the catalogue, so if your setpoint sits near the bottom or top of the standard range, ask us to confirm suitability against the datasheet before ordering.
