The AirTAC GFR200-08 AirTAC Filter Regulator NPT1/4 with Gauge 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 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 sets downstream pressure in a single body. This 200-size unit is threaded 1/4 in NPT, carries the standard 40 um filter element, and drains condensate by differential pressure, so the bowl empties itself whenever the pressure differential across the element is high enough. Outlet pressure is set anywhere in the 0.15-0.9 MPa (20-130 psi) range and read on the fitted round MPa gauge, and the built-in check valve lets downstream air exhaust back through the unit when the supply is shut off. The polycarbonate bowl is protected by a metal bowl guard, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch and a choice of PT, G or NPT threads, manual or automatic drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and a low-pressure regulator type. We confirm flow and datasheet figures on request, as flow for this series is published as curves rather than a single rating.

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.

Clean, regulated air feeding the tool-change clamps and chip-sweep nozzles on a CNC machining centre, with the check valve holding the clamp circuit if the shop air drops.
Setting a stable supply pressure for the vacuum generators and sealing cylinders on a carton-forming and wrapping line, with the 40 um element keeping debris out of the valve bank.
Regulated air to the filler-head and capper cylinders on a beverage bottling line, with the differential-pressure drain clearing condensate that collects during long production runs.
Start by stepping the size to the flow your line needs: 200 is the smallest of the four GFR sizes, and moving up to 300, 400 or 600 buys larger ports and more flow, so it is worth checking the flow curve against your worst-case air demand before settling on 200. Then choose the drain: differential-pressure (this unit, no action needed), automatic for continuous condensate rejection, or manual where an operator drains the bowl on a schedule. Pick the 40 um standard element for general supply air, or the 5 um W element where finer filtration matters; add a gauge in the scale your team reads (MPa, psi or bar); and order the thread your pipework uses - PT is the standard, with G and NPT as order options. Brackets are included unless you specify J for none.
Because flow for the GFR series is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering - we will pull the datasheet for the exact size and port you are considering.
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 number, so there is no one figure we can quote. Tell us your line pressure, set pressure and air demand, and we will confirm from the datasheet whether the 200 size at 1/4 in NPT covers your application before you order.
This unit drains automatically whenever the pressure drop across the 40 um element builds high enough, so no operator action is needed. Choose the M (manual) version if you want the bowl emptied only on a maintenance schedule, or the A (automatic float) version if condensate loads are heavy and continuous.
