The AirTAC GFR20008LC1TK AirTAC Filter Regulator NPT1/4 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 PT1/4" 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 GFR20008LC1TK is an AirTAC GFR200 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is built for 1/4 in NPT ports and carries the standard 40 um filter element, with condensate discharged by the differential-pressure drain. The L in the code marks the low-pressure regulator type, C1 fits the external round gauge with an MPa scale, K adds a reverse (check) valve, and a mounting bracket is included. The bowl on this size is PC (polycarbonate).
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with ports from 1/8 in to 1 in and PT, G or NPT thread options, and other variants are available with manual or automatic drain, the finer 5 um element (code W) and alternative gauge choices. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Rated flow is published only as curves, so ask us to confirm the datasheet figures for 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. 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.

Filtered, regulated air at a reduced downstream setting for pneumatic clamps that must not crush delicate workpieces, with the check valve holding the set pressure against upstream fluctuation.
Water and particulate removed ahead of sealing actuators that run at reduced pressure, protecting seals and valves from condensate carryover on a continuous packaging line.
Clean, moisture-reduced air regulated down to the low pressures atomizing nozzles need, with the MPa gauge giving the operator a direct reading at the booth.
Size 200 with 1/4 in NPT ports suits circuits plumbed at that port; step up to size 300, 400 or 600 when the line needs a larger port and more flow - we will check the flow curve against your demand on request. The 40 um element is the standard grade; specify code W for 5 um where finer filtration is needed. Drain choices are differential-pressure (this unit), automatic (A) or manual (M). The round gauge fitted here reads in MPa, with psi and bar scales as options and the embedded square gauge as the standard alternative. Threads are PT as standard, with G (BSPP) and NPT (this unit, code T) as order options; a bracket is included and can be ordered without (J).
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. 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 rather than a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the datasheet curve and sizing for this unit before you order.
It marks the low-pressure type of the GFR regulator. The exact adjustment range for this variant is not published in the material we hold, so confirm it with us on request. The rest of the code decodes as: size 200, 1/4 in NPT ports, 40 um element, differential-pressure drain, round MPa gauge, check valve fitted, bracket included.
