The AirTAC GFR60025LC2K AirTAC Filter Regulator PT1 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 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 AirTAC GFR60025LC2K is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at a set point, in one body. This size-600 unit is built for 1 inch PT threaded ports and is the low-pressure (L) regulator type. It carries the 40 um standard filter element with a differential-pressure drain, which bleeds collected condensate automatically as air flows through, so no manual draining is needed in normal operation. The aluminium alloy bowl suits this larger size, the fitted round gauge reads in psi so the set point can be checked at a glance, a reverse (check) valve is fitted to hold downstream pressure, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 inch up to 1 inch, in PT, G (BSPP) or NPT thread, with differential-pressure, automatic or manual drains, and 40 um standard or 5 um (W) filtration. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Because rated flow is published as curves rather than a single figure, we confirm the datasheet and flow 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. 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.

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.

Pneumatic clamp cylinders on a CNC fixture often hold workpieces at a deliberately low set pressure to avoid distorting the part. This filter regulator cleans the shop air, holds that low set point, and the check valve helps the circuit hold position if supply pressure dips.
Carton-forming and sealing machines run many air cylinders from a single 1 inch drop. A filter regulator at the drop removes water and pipe scale, keeps actuator speed consistent under a stable set pressure, and the psi gauge lets a technician verify settings without extra tooling.
Large diaphragm and quarter-turn valve actuators on a process skid need clean, dry air at a steady, often low, pressure to stroke smoothly and seat fully. This unit filters the supply, regulates it to the actuator's rated set point, and the bracket allows panel or frame mounting beside the valve manifold.
Size and port set the capacity: within GFR, sizes 200/300/400/600 step up in port and flow, and this unit sits at the top of the range with a 1 inch PT port, so match it against the air demand of your line. The L code makes this the low-pressure regulator type, intended where set points sit below the standard range; the exact adjustment range for this variant is not published, so ask us to confirm it against your set point before ordering. Drain is differential-pressure as coded here, with automatic (A) and manual (M) versions available in the family. Filtration is the 40 um standard element; specify W for 5 um where finer particulate removal matters. The round gauge on this unit reads in psi; the embedded square gauge and MPa or bar scales are the other catalogue options. Thread is PT as standard, with G (BSPP) and NPT available to order, and the bracket is included. Flow is published as curves, not a single rating - send us your flow and pressure requirements and we will confirm sizing from 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and air demand, and we will confirm the flow and datasheet figures for this exact model against your application before you order.
L marks the low-pressure regulator type: this unit is built for applications whose set points sit below the standard version's range. The exact adjustment range for the low-pressure variant is not published in the material we hold, so please ask us to confirm it against your required set point. The rest of the code reads as: 600 size with PT1 (1 inch) PT thread, 40 um filter, differential-pressure drain, round gauge with psi scale, fitted check valve, bracket included.
