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 AirTAC GFR200-08 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 1/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. No gauge is fitted with this configuration, and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl lets you see the condensate level at a glance.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, optional gauge, and PT (standard), G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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. 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.

Point-of-use conditioning for the clean, dry, regulated air feeding tool changers, clamps and pneumatic actuators on a machining centre, where the 5 um element protects fine pilot valves.
Filter and regulate the air feeding cylinders and diverters on a carton or bottle packaging line, with automatic condensate bleeding so the line runs without daily drain checks.
Condition the compressed air feeding lab analysers, sample-handling pneumatics and test rigs, where the 5 um grade and stable regulated pressure protect sensitive instruments.
Start with the port and size: this is the smallest GFR size (200) with a 1/4 in NPT port, so step up to GFR300/400/600 if your line runs larger ports or higher air demand. The 5 um element in this code suits air that feeds sensitive components; choose the standard 40 um grade for general plant air. The differential-pressure drain needs no day-to-day attention, but a manual-drain version is available if you prefer controlled draining. No gauge is fitted here, so add a gauge-equipped variant if you need to set and verify the downstream pressure. Thread is NPT on this code; PT (standard) and G are catalogue options. No mounting bracket is included with the J code.
Sizing note: AirTAC publishes flow for this series as curves, not as a single rated number, so we cannot quote a flow figure here. Send us your application details and we will confirm the datasheet curve and sizing before you order.
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 performance curves rather than a single rated figure, so we do not quote a flow number. Send us your application details and we will confirm the datasheet curve and check the sizing for you before you order.
The W in the code GFR20008JNWT selects the optional 5 um filter element instead of the standard 40 um grade, which suits air feeding sensitive valves and instruments. The N selects the no-gauge configuration, so no pressure gauge is supplied; gauge-equipped variants are available in the same series if you need to read the regulated pressure.
