The AirTAC GFR600C25JC1TK AirTAC Filter Regulator 1 in NPT 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 GFR600C25JC1TK is a size 600 filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This configuration is built around a 1 in NPT port, carries the standard 40 um filter element, and drains condensate by differential pressure, so the bowl purges as the pressure drop across the element builds. Because this is the 600 size, the bowl is aluminium alloy. A round external gauge on an MPa scale lets you read the regulated outlet directly, and the fitted reverse (check) valve holds the downstream setting if upstream supply is interrupted. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in to 1 in, and options include a 5 um element (code W), automatic or manual drains, the embedded square gauge with MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the standard regulation range for this configuration is 0.15-0.9 MPa (20-130 psi). Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application.

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.

Drops off a 1 in compressed-air header feeding filler and capper actuators. The unit strips line water and scale at the 40 um grade and holds a steady regulated pressure to the machines, with the differential-pressure drain clearing condensate as the element loads.
Feeds tool-clamp and chip-clearing cylinders on a machining centre from the shop header. The regulator keeps clamp force consistent between cycles, the check valve holds the downstream setting during supply dips, and the MPa gauge gives the setter a direct reading.
Supplies pneumatic quarter-turn actuators on a process skid. Clean, regulated air protects actuator seals and positioner components, and the aluminium 600-size bowl with differential-pressure drain suits a continuously pressurised line that cannot be opened for manual draining.
Start with the port step: this code is the 1 in NPT version of the size 600 body, the largest in the GFR range, so match it to a main-line or high-consumption drop and verify the flow against the published curve before ordering. Drain choice is a real decision: differential-pressure (this code) purges automatically as the element loads, automatic (A) dumps on a cycle, and manual (M) needs an operator - if compressed air runs continuously, differential-pressure or automatic is the safer pick. The 40 um element here is the standard grade; specify the W code if you need 5 um. The round MPa gauge fitted to this unit reads in MPa; square embedded gauges and psi or bar scales are orderable alternatives. G (BSPP) and NPT threads are catalogue options against the PT standard, and a bracket can be added on codes that carry it. Flow is published as curves, not a single rated figure, so send us your application details and we will confirm sizing from the datasheet 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 the GFR600 series as performance curves, not as a single rated number, so we do not quote a figure that could mislead your sizing. Tell us your inlet pressure, set pressure and expected air consumption, and we will confirm the right size from the datasheet curves on request before you order.
This code uses the differential-pressure drain, the GFR default: condensate is discharged automatically when the pressure drop across the 40 um element builds to a set level, with no operator input. If your line cycles or runs at low differential, the automatic drain (code A) is the alternative; the manual drain (code M) suits intermittent duty where an operator can bleed the bowl. All three are orderable on this family.
