The AirTAC GFR20008LF2TK 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 AirTAC GFR20008LF2TK is a GFR-series filter regulator: one compact body that removes water and particulate from compressed air and regulates downstream pressure. This unit is built on the 200 size with 1/4 in NPT ports, carries the standard 40 um filter element, and drains condensate by differential pressure. It is the low-pressure type (code L), so it is intended for circuits that run below the standard regulation band - the exact low-pressure range is not published, so confirm it with us. The fitted square gauge reads in psi, the K code adds a reverse (check) valve, and a mounting bracket is included. Max inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing), with a polycarbonate bowl on this 200 size.
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, plus options for automatic or manual drains, a 5 um element (code W), G or NPT threads, and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rating, so ask us to confirm the figures 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. 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.

Filtering and regulating the air feeding a carton-sealer's pneumatic cylinders on a packaging line, with the psi square gauge giving operators a local pressure readout at the machine.
Conditioning the air supply to an automated sampling station in a laboratory, where the low-pressure type and 40 um element suit instruments that need a clean, gently regulated supply.
Serving a robot gripper circuit on an electronics assembly cell: the fitted check valve guards the set circuit against backflow, and the included bracket simplifies mounting beside the cell.
Size and port set the flow path: the 200 size with 1/4 in NPT ports is the entry step of the GFR range, while 300, 400 and 600 sizes carry larger ports and more flow. This unit is the low-pressure type - if your circuit runs at standard shop-air pressures, the standard GFR version may be the better match, and we can confirm the low-pressure range on request. Drain here is differential-pressure; automatic (A) and manual (M) versions exist. The element is the 40 um standard (5 um available as code W), the square gauge reads psi (MPa or bar scales are options), the thread is NPT (PT is the standard thread, G is also a catalogue option), and a bracket is included. Because flow is published as curves, not a single rating, ask us to check sizing against your application before ordering.
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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for this exact model on request.
The L code marks the low-pressure regulator version, intended for circuits that run below the standard regulation band. The exact low-pressure range is not published in our data, so confirm it with us before ordering. Everything else decodes normally: NPT1/4 ports, 40 um element, differential-pressure drain, psi square gauge, fitted check valve and included bracket.
