The AirTAC GFR200-08 AirTAC Filter Regulator, PT1/4, 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 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 200-size unit is fitted with a PT1/4 (1/4 in) port, the standard 40 um filter element and a differential-pressure drain, so collected condensate is expelled automatically when the pressure differential across the drain is sufficient. It is the low-pressure (L) type, intended for circuits that run below standard regulation ranges. The polycarbonate bowl (sizes 200/300/400 use PC; only size 600 uses aluminium alloy) carries an embedded square gauge scaled in psi, and a reverse/check valve is fitted to hold downstream pressure if the supply is lost. A mounting bracket is 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, a choice of differential-pressure, automatic or manual drains, an optional 5 um (W) element, gauge scale options and G or NPT thread variants to order. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet details 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.

Air cylinders that clamp workpieces at reduced pressure need clean, regulated air. The GFR200-08 filters water and swarf from the shop line and holds the set pressure, with the check valve maintaining the clamp if the main supply drops.
Spray equipment running at low regulated pressure benefits from filtered, moisture-reduced air. The 40 um element and differential-pressure drain keep water and particulate out of the spray circuit without daily manual draining.
Packaging lines use low-pressure actuation for diverters, pushers and gate cylinders. This unit conditions and regulates the branch feed, and the psi-scaled gauge lets operators verify the set point at a glance.
Start with the port step: 200 size covers PT1/4 here, while 300/400/600 step up to larger ports and higher flow capacity, so match the size to the air demand of the circuit rather than the fitting alone. Choose the drain: differential-pressure (this unit) needs no operator attention, automatic drains continuously, and manual suits infrequent condensate loads. Filter grade is 40 um as standard; specify the W code if the application needs 5 um. The embedded square gauge is supplied scaled in psi (MPa and bar scales are alternatives), and an external round gauge is optional. Thread is PT as standard; G (BSPP) and NPT are order options. A bracket is included with this unit, and the K code means a reverse/check valve is fitted. Because flow is published as curves rather than a single rating, 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 figure, so we do not quote a number. Tell us your application and we will confirm the flow data from the datasheet on request before you order.
The L code makes this a low-pressure regulator type, intended for circuits running below standard regulation ranges; the exact range is not published, so confirm it with us. The K code means a reverse/check valve is fitted, which holds downstream pressure if the supply is interrupted.
