The AirTAC GFR20008LF2G AirTAC Filter Regulator, Low-Pressure, G1/4 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 GFR20008LF2G is an AirTAC GFR200 filter regulator: a single body that removes water and particulate from compressed air and holds downstream pressure at the set point. This 200-size unit carries a 1/4 in (G1/4) port, a 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically as flow passes through. It is the low-pressure type, and the fitted square gauge reads in psi so operators can check and adjust the downstream setting at a glance. The polycarbonate bowl suits the 200 frame, and a mounting bracket is included for panel or frame fixing.
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, optional 5 um elements, automatic or manual drains, and a choice of gauge scales and thread standards (G, NPT or PT). Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

On a carton-sealing or wrapping line running at reduced air pressure, this unit filters the supply and holds a gentle, stable setting so sealing cylinders and vacuum generators behave consistently shift after shift.
At a bench drop feeding air-operated valves or sample-handling actuators, the 40 um element keeps particles and condensed water out of sensitive components while the psi gauge lets technicians verify the set point.
Fixture clamps that must not see full line pressure benefit from the low-pressure regulation: filtered air at a controlled setting keeps clamp force repeatable, and the differential-pressure drain handles condensate without operator attention.
Start with the port step: this unit is 1/4 in (G1/4) on the 200 frame; step up to GFR300/400/600 when the line needs larger ports and more flow. The 40 um element is the standard grade; specify the W suffix for a 5 um element where finer filtration is needed. Drain choice matters: differential-pressure (as fitted here) needs no attention, automatic drains continuously, and manual suits intermittent-duty installations. Gauge options are the embedded square gauge (psi here) or an external round gauge in MPa, psi or bar scales; thread is G here, with PT standard and NPT available to order. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing 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 this family as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, downstream demand and allowable pressure drop, and we will confirm the correct size from the datasheet on request.
The F2 code in GFR20008LF2G specifies the embedded square gauge with a psi scale, which is the fitted standard. An external round gauge is optional, and scales are available in MPa, psi or bar - just ask when ordering. The G thread on this unit is an order option; PT is the catalogue standard and NPT is also available.
