The AirTAC GFR600C25MLF2TK 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 See datasheet 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 AirTAC GFR600C25MLF2TK is a size-600 filter regulator: water and particulate filtration plus pressure regulation in a single body, sized for a 1 in (NPT1) port. This configuration carries the standard 40 um filter element, a manual drain on the bowl, a low-pressure regulator type, an embedded square gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure when the upstream supply is lost. The bowl on size-600 units is aluminium alloy, and the mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing); the medium is compressed air only.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in. Across the family you can order manual, automatic or differential-pressure drains, a 5 um (code W) element instead of the 40 um standard, square or external 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 and we will confirm the datasheet figures for your application on request.

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 0.15 - 0.9 MPa (20 - 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.

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.

Feeding the low-pressure circuits that operate mould-closing and take-out mechanisms on an IS machine, where a 1 in supply serves several large actuators and the check valve holds settings during brief supply interruptions.
Regulating and filtering the air to heavy log clamps and hold-down cylinders on a saw line, with the manual drain bled at shift start and the 40 um element protecting the large valve spools.
Conditioning the supply to vacuum-assist and hold-down actuators along a corrugator transfer section, where the psi square gauge lets operators verify set pressure at the machine and the aluminium bowl suits a warm, dry compressor room.
Start with the port step: this unit is the size-600, 1 in (NPT1) member of the range, the largest in the family - step down to 300/400 (3/8 to 3/4 in) if your line diameter and flow demand are smaller. Drain choice matters in duty terms: the manual drain fitted here means an operator bleeds the bowl, so choose automatic or differential-pressure drainage if the installation is unattended. The 40 um element is the standard grade; specify code W for 5 um if downstream equipment needs finer filtration. This is the low-pressure regulator type, so confirm the control band suits your circuit - the exact range for this variant is not published and we will confirm it on request. The square gauge here reads psi; MPa and bar scales and an external round gauge are alternatives. Thread is NPT on this code; PT is the catalogue standard and G (BSPP) is also orderable. A bracket is included.
One honest note before you order: AirTAC publishes flow as curves, not a single rated number, so we do not quote a flow figure here. Send us your application and we will confirm sizing against the datasheet curves before you commit.
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 this family as curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number here. Send us your line size and demand and we will confirm the flow from the datasheet curves for your application on request before you order.
The M in the code specifies a manual drain: condensate collected in the aluminium bowl is released by an operator, which suits attended installations on a maintenance round. If the unit will run unattended, order the same size with an automatic (A) or differential-pressure (blank) drain; note that the regulator adjustment range differs by drain type, and for this low-pressure variant we will confirm the exact range on request.
