The AirTAC GFR20008LF1T AirTAC Low-Pressure Filter Regulator NPT1/4 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 PT1/4" 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 GFR20008LF1T is an AirTAC GFR200 filter regulator: water and particulate filtration plus downstream pressure regulation in one body. This configuration is the low-pressure regulator type (code L) with 1/4 in NPT ports, a 40 um standard filter element, and a differential-pressure drain, which is the standard drain option. A square pressure gauge scaled in MPa is fitted, a mounting bracket is included, the bowl is polycarbonate (PC), maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with ports from 1/8 to 1 in and options including a 5 um element (code W), automatic or manual drains, gauge scales in psi or bar, an external round gauge, and G (BSPP) thread in place of the PT standard. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

On a CNC machining cell, the low-pressure regulator holds a reduced, steady clamp pressure for aluminium fixtures while the 40 um element and differential-pressure drain keep water and grit out of the clamp cylinders.
Feeding the diverters and pusher cylinders on a packaging conveyor, this unit filters condensed water from the header supply and lets an operator set a lower working pressure for handling delicate cartons.
In a small finishing shop, the low-pressure type supplies spray guns at reduced, adjustable pressure, with the 40 um element and differential-pressure drain doing the job of keeping water and particulate out of the air stream.
This unit's choices are fixed by the code: size 200 with 1/4 in NPT ports, low-pressure regulation, 40 um standard filtration, differential-pressure drain, square MPa gauge, bracket included. When sizing, the first decision is the size and port step - GFR bodies run 200, 300, 400 and 600 with ports from 1/8 to 1 in - and the right step depends on the flow your line needs. Other orderable choices: a 5 um element (code W) for finer filtration, an automatic or manual drain instead of the differential-pressure type, gauge scale 2 (psi) or 3 (bar), G (BSPP) thread, or no bracket (code J). Because AirTAC publishes flow as curves rather than a single rating, send us your application details and we will confirm the correct size before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. 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 number here. Send us your inlet pressure, downstream demand and port size, and we will confirm the flow and datasheet figures for this exact model on request.
L marks the low-pressure regulator type. This unit regulates downstream pressure in the low-pressure class rather than the full standard range, and the exact adjustment window for the low-pressure type is not published on our sheet - ask us to confirm it against your setpoint before ordering.
