The AirTAC GFR200-08 NPT AirTAC Filter Regulator, 1/4 in, Manual Drain 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 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: one body that removes water and particulate from compressed air and regulates downstream pressure. This 200-size unit is threaded 1/4 in NPT, has a manual drain on the polycarbonate bowl, a 40 um standard filter element, an embedded square gauge scaled in MPa, a built-in check valve that blocks reverse flow, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, an optional 5 um element (code W), automatic or manual drain choices, G/NPT thread options, and gauge variants. Flow is published as curves rather than a single rating, 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 0.05 - 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.

Filtering and regulating the 1/4 in supply to a pick-and-place robot's gripper circuit at a single workstation, with the embedded gauge giving a local pressure check.
Conditioning air at the drop feeding a carton-sealing machine's cylinders and directional valves, where one compact body handles both filtration and regulation.
Supplying regulated air to the clamps on a machining fixture, with the built-in check valve blocking backflow toward the supply side.
Size the unit by port and expected flow: 200 is the smallest GFR size, here with a 1/4 in NPT port; step up to 300, 400 or 600 for larger ports. This code specifies a manual drain, so bleed the bowl by hand during routine checks; the same size is available with an automatic drain (code A) or the default differential-pressure drain. The 40 um element is standard; specify W for 5 um. The embedded square gauge is scaled in MPa, with psi and bar scales and an external round gauge as order options. NPT is the thread on this code; G (BSPP) and PT are catalogue alternatives. Flow is published as curves, not a single rated figure - 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the datasheet curve for this 1/4 in unit before you order.
This code has a manual drain: open the bowl drain by hand as part of routine maintenance. If you prefer unattended condensate removal, the same size is available with an automatic drain (code A) or the default differential-pressure drain - just ask for the alternative code.
