The AirTAC GFR200-08 AirTAC Filter Regulator NPT1/4, 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR200-08 is an AirTAC GFR200 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration has 1/4 in NPT ports, the fine 5 um filter element (code W), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a built-in reverse (check) valve so downstream pressure is held if the supply is interrupted. No gauge is fitted (code N), so add a separate gauge if you need a local setpoint readout; a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part, not a copy. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge, thread (PT standard, G and NPT as options) and bracket. Flow is published as curves rather than a single rating, so we confirm the flow and datasheet figures for your application 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. 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.

Feeding clean, regulated air to a machining centre's pneumatic tool-clamp and chip-ejection circuits, where the 5 um element protects precision valves and the check valve holds clamp pressure during supply dips.
Conditioning the air that actuates conveyor diverters, carton sealers and case-packing cylinders, with regulated pressure keeping actuation consistent across the line and the differential drain clearing condensate as product flows.
Supplying filtered, regulated air to lab automation grippers and sample-transfer cylinders, where the fine 5 um grade and stable setpoint protect sensitive motion components and the bracket gives tidy panel mounting.
Start with the port and size step: this unit is size 200 with 1/4 in NPT ports; if your line needs more flow, step up to GFR300/400/600 rather than oversizing elsewhere. The 5 um element (code W) suits instruments, valves and cylinders that need finer air than the standard 40 um grade; keep 40 um in mind for general shop air where finer filtration is not required. The differential-pressure drain is the default and needs no timer or operator; choose automatic drain (A) or manual drain (M) variants if your duty cycle or access calls for it. No gauge is fitted, so specify a separate gauge in the scale you prefer (MPa, psi or bar). NPT is the thread on this code; PT is the AirTAC standard and G (BSPP) is also orderable. A mounting bracket is included. 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 rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the flow your application needs, and we will confirm against the datasheet curves whether the size 200, 1/4 in port unit is correctly sized before you order.
The N in the code means no gauge is fitted, so add a separate gauge in MPa, psi or bar scale if you need a local readout of the setpoint. The K code means a reverse (check) valve is built in: if the upstream supply drops, it holds the regulated downstream pressure instead of letting it vent back, which protects cylinders and clamps on the outlet side.
