The AirTAC GFR60025MC2WTK AirTAC Filter Regulator 1 in NPT, 5 um 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60025MC2WTK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This configuration is built for a 1 in NPT port, filters to 5 um for finer protection than the standard 40 um element, and uses a manual drain, so an operator opens the drain at the bowl to discharge collected condensate. It ships with a round gauge reading in psi, a reverse/check valve to hold downstream pressure when the supply drops, and a mounting bracket. The aluminium alloy bowl suits this largest size in the range.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge scale in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application before you order.

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 0.05 - 0.9 MPa (7 - 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.

| 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 at the take-off from a 1 in compressed-air ring main, it cleans the supply to 5 um and holds a set header pressure for the whole workshop, with the check valve holding the line up during brief supply dips.
Feeding the cylinder and gripper manifold on a bottling or cartoning line, it keeps regulator pressure steady so conveyor stops, pushers and clamps repeat their stroke consistently shift after shift.
Mounted ahead of a machining centre's air inlet, it strips water and fine particles before they reach the spindle clamp and tool-change circuits, and the psi gauge gives operators a visible set point at the machine.
Start with the port and size: the 600 frame with a 1 in NPT port is the right choice when your main air line is 1 in and your demand sits at the top of the G-series flow range - match the published flow curve to your consumption rather than guessing. Choose the drain to suit access: manual (this unit) needs someone to open the bowl drain periodically; automatic or differential-pressure draining suits unattended installations. This unit carries the 5 um (W) element where downstream equipment needs finer filtration than the 40 um standard. The round gauge here reads in psi; MPa and bar scales are available, and an embedded square gauge is the alternative. Thread is NPT on this code, with PT (standard) and G offered as order options; a bracket is included.
Because flow is published as curves and not a single rating, send us your line size and air 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line size and air demand and we will confirm the flow-curve figures from the datasheet against your application before you order.
The M in the code selects the manual drain: condensate collected in the aluminium bowl is released by opening the drain when you walk the line, rather than automatically. If the installation runs unattended, ask us about the same unit with automatic or differential-pressure drain instead.
