The AirTAC AirTAC GFR200-08 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 has a 1/4 in PT port, the standard 40 um filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. It is the low-pressure type, and the embedded square gauge is fitted with a psi scale so the set pressure can be read directly. A mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator range, which spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, manual or automatic drain options, a 5 um (W) filter grade, and MPa, psi or bar gauge scales. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Clean, regulated air feeding solenoid valves and air bearings on a machining centre, with the 40 um element catching pipe scale and the psi gauge giving the setter a direct reading.
A filter regulator ahead of the cylinder bank on a carton-sealing conveyor, keeping moisture and debris out of the valves while holding a gentle, low set pressure for the gripper cylinders.
Conditioning the air supply to a lab analyser cabinet, where the low-pressure type regulator trims the feed down to a mild purge pressure and the drain keeps condensate out of the instrument.
Start with the port step: the 200 size carries 1/4 in PT threading here, and larger sizes (300/400/600) step up in port and flow capacity, so match the size to the air demand of the circuit. The 40 um standard element suits general plant air; choose the 5 um (W) grade where finer particulate removal is needed. Drain choice matters: this unit uses the differential-pressure drain (default); automatic (A) and manual (M) drains are available in the family. The fitted square gauge here reads in psi; MPa and bar scales, and an external round gauge, are the other options. PT is the standard thread; G (BSPP) and NPT are catalogue options to order, and a no-bracket (J) variant exists. 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. Without the K option, air cannot flow back 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 here. Tell us your application and we will confirm the flow and datasheet figures for the GFR200-08 on request before you order.
L is the low-pressure type regulator, F is the embedded square gauge, and 2 is the psi gauge scale. The 08 gives the 1/4 in PT port, the 200 is the size, and with no drain letter the unit carries the differential-pressure drain and the standard 40 um filter element.
