The AirTAC GFR200-08 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 GFR200-08 is a size-200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the low-pressure type with a 1/4 in NPT port, a 40 um standard filter element, and a differential-pressure drain that bleeds condensate automatically as flow passes through. A square pressure gauge (psi scale) is fitted so you can set and monitor the outlet setting, and a reverse/check valve is fitted to hold the downstream setting if upstream supply is interrupted. No mounting bracket is included with this code.
This is a genuine AirTAC part from the GFR200 series, one of four sizes (200/300/400/600) with port options from 1/8 in to 1 in and PT, G or NPT threads. The low-pressure type is intended for circuits that run below standard regulator settings; its exact adjustment range is not published in the material we hold, so ask us to confirm it against your setpoint. Flow is published as curves rather than a single rating - we confirm datasheet figures 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.

Supplying filtered, low-pressure regulated air to pneumatic clamps and workholding fixtures on a machining centre, with the psi gauge letting the setter verify the clamp circuit setting at the panel.
Conditioning and regulating the air feeding seal bars and low-pressure actuator circuits on a packaging line, with the check valve holding the downstream setting during brief supply dips.
Providing water- and particulate-filtered air at a reduced, stable setting to spray and coating test benches, where the low-pressure type suits circuits running below standard regulator ranges.
Start with the port: this code is the 1/4 in NPT version of the GFR200. If your line needs more flow than the size-200 curve supports at your allowable pressure drop, step up to GFR300/400/600 rather than oversizing the regulator setting. Drain choice matters: the differential-pressure drain fitted here is the fit-and-forget option; choose automatic (code A) for intermittent-flow circuits where the differential bleed will not act, or manual (code M) where you want controlled draining. The 40 um element suits general pneumatic supply; specify the W code for a 5 um element where finer particulate protection is needed. The square psi gauge is fitted here; external round gauges and MPa/bar scales are order options. Thread: PT is the standard, G and NPT are order options - this code carries NPT. No bracket is included; add one if the unit will not be mounted on a manifold or wall plate.
Because flow is published as curves, not a single rated figure, ask us to confirm 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 flow for the GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your operating pressure, allowable pressure drop and expected air demand, and we will confirm the sizing from the datasheet curves on request before you order.
The L code makes this a low-pressure type, intended for circuits that run below standard regulator settings; its exact adjustment range is not published in the material we hold, so confirm it with us against your setpoint. The differential-pressure drain (the default, no drain code) bleeds collected condensate automatically as air flows through, which suits continuously flowing lines. For circuits with long idle periods, the automatic-drain version (code A) is the better choice.
