The AirTAC GFR200-08 AirTAC Filter Regulator, PT1/4, 5 um, Manual Drain 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 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 GFR-series filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is the size 200 unit with a 1/4 in PT port, 5 um filtration (the finer W grade), a manual drain for emptying the bowl, an embedded square gauge reading in psi, a fitted reverse/check valve, and a mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range with manual drain is 0.05-0.9 MPa (7-130 psi), and the operating temperature is -5 to 70 C (non-freezing). The polycarbonate bowl lets you see condensate level at a glance.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, thread options PT (standard), G and NPT, drain choices of differential-pressure, automatic or manual, filter grades of 40 um standard or 5 um, and gauge scale options. Flow is published in the catalogue as curves rather than a single rated figure, 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 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.

Installed at the drop to a machining centre's pneumatic circuit, the GFR200-08 cleans the shop air to 5 um and holds a steady regulated pressure to the tool changer, clamps and air blast, with the psi gauge giving the operator a direct reading at the machine.
Mounted ahead of the valve manifold on a packaging conveyor, this unit filters water and fine particulate out of the supply and regulates pressure to the sealing and diverting cylinders, with the check valve holding the downstream setting if supply pressure dips.
Feeding purge air or actuation air to lab analysers and enclosed instruments, the 5 um element protects sensitive pneumatic components, the manual drain suits a supervised lab environment, and the bracket allows clean panel-adjacent mounting.
Start with the size and port: this is size 200 with a 1/4 in PT port, the right step when your line pressure supply and downstream piping are 1/4 in and your air demand sits in the smaller size class. Sizing against required flow matters most, and because AirTAC publishes flow as curves rather than a single rating, ask us to confirm the curve against your application before ordering. This unit carries the 5 um (W) element instead of the 40 um standard - choose 5 um where downstream valves, cylinders or instruments need finer particulate removal. The manual drain means an operator opens the drain to expel collected condensate, which suits periodically attended installations; if the unit is hard to reach, ask about the automatic or differential-pressure drain versions. The fitted square gauge reads in psi; MPa and bar scales are alternatives. Thread is PT as standard, with G and NPT available as order options, and the mounting bracket is included.
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 flow data from the datasheet and check the sizing against your demand before you order.
The M in the code selects the manual drain: condensate collected in the polycarbonate bowl is released by opening the drain by hand. That suits installations someone visits regularly. If the unit will be mounted where it cannot be checked often, ask us about the automatic or differential-pressure drain variants of the same GFR200 size.
