The AirTAC GFR20008LF2W AirTAC Filter Regulator 1/4 in, Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR20008LF2W is an AirTAC GFR200 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air down to 5 um (the finer W-grade element, versus the 40 um standard) and regulates downstream pressure in a low-pressure configuration. This unit is built with a 1/4 in PT port, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, a fitted embedded square gauge scaled in psi, and a mounting bracket included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and choices of drain type, filter grade, gauge scale and thread (PT standard, with G and NPT available as order options). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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. 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 fixture-clamping circuit that runs at reduced pressure, this unit filters the supply to 5 um and holds the regulated setpoint, with the psi square gauge giving the operator a direct readout at the station.
A lab bench running pneumatic test rigs benefits from the 5 um element protecting fine instrumentation and the low-pressure regulator trimming supply pressure, while the differential-pressure drain keeps condensate off the bench.
On a packaging line where sealing bars or low-pressure actuators need gentler regulated air than the main supply, this 1/4 in filter regulator drops and cleans the feed at the point of use.
Start with the port step: this unit is size 200 with a 1/4 in PT port, the smallest GFR size - step up to 300, 400 or 600 if your line needs larger ports and flow capacity. The 5 um W-grade element suits air that feeds sensitive components; the 40 um standard grade is enough for general circuits. Drain options are the differential-pressure drain fitted here, an automatic drain (code A) or a manual drain (code M). The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and the bracket is included. Note this is the low-pressure (L) type - its regulation range is not published in the standard table, so flow is published as curves rather than a single rating: ask us to confirm sizing and the regulation range against your application before ordering.
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 G-series flow as curves, not as a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the relevant flow and datasheet figures for this 1/4 in unit on request before you order.
L marks the low-pressure regulator type - its exact regulation range is not published in the standard table, so ask us to confirm it for your setpoint. W marks the 5 um filter element, the finer option versus the 40 um standard grade. The unit also carries a differential-pressure drain, a psi square gauge, and a mounting bracket.
