The AirTAC GFR60025LC2WTK AirTAC Filter Regulator 1 in NPT 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 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 GFR60025LC2WTK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is built with a 1 in NPT port, the 5 um filter element (code W), a differential-pressure drain, and the low-pressure regulator type (code L). The code also specifies a round gauge with a psi scale (C2), a reverse/check valve (K), and an included mounting bracket. At size 600 the bowl is aluminium alloy, and the unit handles up to 1.0 MPa (145 psi) inlet pressure between -5 and 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 to 1 inch, a choice of 40 um standard or 5 um filtration, differential-pressure, automatic or manual drains, standard or low-pressure regulation, gauge and thread options, and optional brackets. 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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

| 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. |
| 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 a 1 in NPT supply drop feeding a machining cell, this unit strips water and swarf-carrying particulate from the shop air and sets the header pressure for every valve and cylinder downstream. The aluminium size 600 bowl and included bracket suit a fixed wall-mounted installation point.
On a pallet-clamping or workholding circuit where the regulated setting sits below what a standard-type regulator targets, the low-pressure regulator type (L) in this code is the specified choice. The 5 um element keeps fine particulate out of the clamp cylinders and control valves; confirm the exact adjustment range with us before ordering.
Fitted at the head of a 1 in feed to a bottling or packaging line, this filter regulator cleans the compressed air before it reaches the line's actuators and sets the operating pressure for the conveyor stops, grippers and diverters. The fitted reverse/check valve and round psi gauge give the line a visible, held setpoint.
Work through the decode choices in order. Size 600 with a 1 in port is the largest step in the GFR range; match it to the air demand of the line, and ask us to check the flow curve against your consumption before ordering. The 5 um element (W) suits points where finer particulate removal matters; the 40 um standard element is the default for general supply. Drain here is differential-pressure, which clears the bowl based on the pressure differential; automatic (A) and manual (M) drains are orderable alternatives. This unit is the low-pressure regulator type (L), so confirm its adjustment range with us rather than assuming a standard-type figure. The round psi gauge (C2) is fitted; square-gauge and MPa/bar scale options exist. Thread is NPT on this code; PT is the standard and G (BSPP) is orderable. A mounting bracket is included.
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 the GFR family as curves, not as a single rated number, so we do not quote a figure here. Send us your line pressure, required downstream pressure and air consumption, and we will confirm the sizing from the datasheet on request.
The W in the code selects the 5 um filter element instead of the 40 um standard, and the L selects the low-pressure regulator type. Both are order-time choices on the GFR family. The exact adjustment range of the low-pressure type is not published on the catalogue sheet we work from, so we confirm it on request.
