The AirTAC GFR200-08 AirTAC Filter Regulator 1/4 in PT, 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: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is the 200 size with a PT1/4 (1/4 in) port, a fine 5 um filter element, and a differential-pressure drain that bleeds collected condensate automatically as pressure differential builds. The standard regulator covers 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the embedded square gauge reads in psi so setpoints can be checked at a glance. A reverse/check valve is fitted, and the polycarbonate bowl suits sizes 200-400 (size 600 uses an aluminium alloy bowl). No mounting bracket is included in this configuration.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, choice of PT, G (BSPP) or NPT thread, differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, gauge scale options, and an optional check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet figures against 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.

On a packaging-line robot cell, clean 5 um air and a stable regulated supply keep gripper and clamp cylinders repeating their stroke consistently shift after shift, while the check valve holds the circuit if upstream pressure dips.
Air-prep at each valve manifold on a bottling line: the filter-regulator strips water and fine particles before pneumatic valves and the psi gauge lets line technicians verify setpoints without extra instruments.
Feeding tool-changer and clamping circuits on a CNC machining centre, the 5 um element protects sensitive directional valves and the regulator holds the pressure the machine builder specifies.
Size and port step up together: 200 with 1/4 in here, then 300, 400 and 600 as required flow grows - match the size to the air demand of the circuit rather than the pipe alone. Drain type is a real choice: differential-pressure (as fitted here) and automatic drains look after condensate for you, while manual drain suits supervised installations; note the regulation range differs by drain type (0.15-0.9 MPa for differential-pressure and automatic, 0.05-0.9 MPa for manual). Filter grade is 40 um standard or 5 um (W) for finer protection - this unit carries the 5 um element. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) are selected at ordering, and a bracket is optional - this configuration ships without one. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing before you order.
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 a rated flow, Cv or SCFM number. Send us your application details and we will confirm the flow and datasheet figures for this 200-size, 1/4 in unit on request before you order.
This unit has a differential-pressure drain: condensate collected in the polycarbonate bowl is bled off automatically as the pressure differential across the drain builds, with no operator action. The GFR family also offers automatic (code A) and manual (code M) drains. Note the regulator adjustment range depends on drain type: 0.15-0.9 MPa (20-130 psi) for differential-pressure and automatic drains, and 0.05-0.9 MPa (7-130 psi) for manual drain.
