The AirTAC GFR200C08MJF3WTK AirTAC Filter Regulator NPT1/4, 5 um 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 See datasheet 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 GFR200C08MJF3WTK is a size-200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1/4 in NPT port, a fine 5 um filter element, a manual drain on the metal bowl, an embedded square gauge scaled in bar, and a built-in reverse/check valve, and it ships without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with larger ports and higher flow at each step. Drain, filter grade, gauge style and scale, thread (PT standard, G and NPT as options), bracket and check-valve choices let you match the unit to the line. Flow is published as curves rather than a single rating, so ask us and we will confirm the 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 tool-clamp and chip-clearing cylinders on a machining centre: the 5 um element protects the directional valves from water and fine dirt while the regulator holds a steady set pressure at the clamp circuit, and the check valve backs up the supply if the main air drops.
Point-of-use prep on a cartoning or pouch line: clean, regulated air to the diverters, sealers and reject pushers right at the machine, with the square bar gauge letting an operator verify set pressure at a glance and the manual drain cleared during shift start-up.
Supplying bench-mounted test rigs and analytical instruments that need dry, particle-free air at a fixed pressure: the fine 5 um grade and close regulation protect sensitive pneumatic controls, and the compact size-200 frame fits a crowded bench without a bracket.
Start with the port step: this unit is the 1/4 in NPT version of the size-200 frame; step up to 300, 400 or 600 when the line needs a larger port and more flow. Because the drain here is manual, plan a routine blow-down of the bowl - an automatic or differential-pressure drain version removes that task if nobody is at the machine. The 5 um element (code W) suits air that feeds sensitive valves and instruments; the standard grade is 40 um if coarse protection is enough. The square gauge reads in bar; MPa and psi scales and an external round gauge are alternatives. Thread is NPT on this unit - PT is the standard and G is also an order option - and the bracket is omitted (code J), so add mounting separately if the unit will not hang on the port. Flow for this family is published as curves, not a single rating, so 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. 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 curves, not as a single rated number, so we do not quote a figure that could mislead your sizing. Tell us your line pressure, set pressure and expected air demand and we will confirm the flow data from the datasheet for this exact model on request.
M in the code is the manual drain: someone opens the bowl drain to expel collected water, which suits machines that are attended regularly. The trailing K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply is lost. Automatic and differential-pressure drains are available on other GFR codes if you prefer unattended drainage.
