The AirTAC GFR600C25MJC2GK AirTAC Filter Regulator 1 in G-Thread 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 GFR600C25MJC2GK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body, so one unit does the job of a filter and a regulator without a separate joining kit. This configuration is the size 600 (largest) unit with a G1 (1 in) G-thread port, a manual drain bowl in aluminium alloy, a 40 um standard filter element, a round pressure gauge reading in psi, a built-in reverse/check valve, and no mounting bracket. The manual drain means an operator opens the bowl drain to expel collected condensate, which suits installations that are checked as part of a routine walk-round. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range on this manual-drain version is 0.05-0.9 MPa (7-130 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, and options include automatic or differential-pressure drains, a 5 um element (code W), embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and check sizing against 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. 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.

Installed at the take-off point of a factory compressed-air ring main to deliver clean, regulated air to a production cell, with the 1 in port matching the header drop and the manual drain cleared during daily checks.
Fitted ahead of a CNC machine's air service inlet to remove water and chips-carried particulate and hold a stable set pressure for tool-change and clamping circuits, with the psi gauge giving the operator a direct reading.
Used on a heavy-truck fleet's service-bay air drops to condition and regulate shop air for tyre inflation and air-tool circuits, with the check valve holding the downstream circuit if supply pressure dips.
Start with the port and size step: GFR units run from size 200 (1/8-1/4 in ports) up to size 600 (1 in), and the larger the size the larger the port and the greater the flow capacity - match the step to the air demand of the circuit rather than oversizing on guesswork. Choose the drain to suit how the unit is attended: manual (this model) for checked installations, automatic where condensate must be expelled without operator action, or the differential-pressure default. Filter grade is 40 um as standard for general protection, with the 5 um W element for finer pre-filtration. Gauge scale is selectable (MPa, psi or bar) and the gauge can be the embedded square type or an external round gauge. Thread is PT as the catalogue standard, with G and NPT as order options; a mounting bracket is optional (this model is supplied without one). Flow is published as curves, not a single rating, so send us your application details 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 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. Tell us your application and required flow, and we will confirm the correct figure from the datasheet and check the sizing with you before you order.
The M in the code GFR600C25MJC2GK specifies a manual drain: condensate collected in the bowl is expelled by opening the drain by hand, which suits installations checked on a regular routine. If the unit will be left unattended, the same GFR600 body is available with an automatic drain (code A) or the differential-pressure drain (the default, no code) - just ask and we will quote the variant.
