The AirTAC GFR200-08C2K AirTAC Filter Regulator PT1/4 40 um 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 GFR200-08C2K is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-200 unit has a PT1/4 (1/4 in) PT thread, 40 um standard filtration, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential is high enough, so no manual draining routine is needed. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, a round external gauge reading in psi is fitted, and a reverse (check) valve is built in, so downstream pressure is held if the upstream supply drops.
This is a genuine AirTAC part. The GFR series is made in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include a 5 um filter element (code W), automatic or manual drains, alternative gauge scales in MPa or bar, G (BSPP) or NPT threads, and low-pressure or no-bracket variants. 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

Filter and regulate the shop-air feed to a CNC machining centre's pneumatic clamps and tool-change cylinders, with the check valve holding the clamp circuit if the main supply dips.
Condition the air feeding conveyor stoppers, diverters and case-erector cylinders on a packaging line, keeping water and debris out of the valves while holding a set working pressure.
Supply filtered, regulated air to laboratory automation equipment such as plate handlers and pneumatic pipette drives, where the psi gauge gives a readable setpoint for the instrument's air circuit.
Start with the port step: this unit is size 200 with a PT1/4 (1/4 in) PT thread; if your line needs more flow, the GFR300/400/600 sizes step up in port and body size. The 40 um element suits general-purpose air; specify the W variant if you need 5 um. Drain choice matters: differential-pressure (this unit) drains itself with the flow, automatic drains on a timer-free principle, and manual drain suits infrequently visited installations. The fitted round gauge reads psi; MPa or bar scales are available, and the embedded square gauge is the standard alternative. G (BSPP) and NPT threads are order options alongside the PT standard, and a bracket can be omitted with the J code. Because flow is published as curves, not 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 number, so we do not quote a figure here. Tell us your application and we will confirm the relevant flow and datasheet figures for this exact model on request before you order.
C is the gauge code: a round external gauge with a psi scale is fitted on this unit (the embedded square gauge is the standard alternative, with MPa or bar scales available). K means a reverse (check) valve is built in, so downstream pressure is retained if the upstream supply is lost. The blank drain position is the differential-pressure type, and the blank filter position is the 40 um standard element.
