The AirTAC GFR200-08 AirTAC Filter Regulator 1/4 in PT, 40 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 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 regulates downstream pressure in a single body. This size 200 unit is threaded PT1/4 (1/4 in), carries a 40 um standard filter element, and drains condensate by differential pressure, so the bowl purges as the pressure differential across the element builds. The fitted square gauge reads in psi, and the regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range. No mounting bracket is fitted on this configuration.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G or NPT threads. Drain, filter grade, gauge style and scale are selectable. Flow figures for this series are 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.

On a bench or gantry press fed from a shop-air drop, the GFR200-08 cleans the supply at 40 um and lets the operator set a stable working pressure on the psi gauge before it reaches the cylinder valve.
On cartoning or wrapping machinery with 1/4 in PT air drops to actuators and grippers, this unit filters water and debris from the main supply and holds the set pressure so pick-and-place motions stay consistent.
On loom and winding-machine control circuits in a textile mill, the unit conditions the branch line and regulates it to the pressure the solenoid valves were sized for, with the differential-pressure drain handling condensate as the line breathes.
Start with the port step: size 200 with a 1/4 in PT port suits compact branch lines, while larger GFR sizes (300/400/600) step up to bigger ports for higher-demand circuits - match the size to the flow your line needs. Choose the drain: differential-pressure (as here) purges automatically under flow, an automatic drain (code A) empties continuously, and a manual drain (code M) is emptied by hand. Pick the filter grade: 40 um standard for general air, 5 um (code W) for finer protection. Gauge style (square embedded or optional round external) and scale (MPa, psi or bar) are your choice, as is the thread: PT is standard, with G (BSPP) and NPT as orderable options, and a bracket can be added or omitted.
Because flow for this series is published as curves and not as a single rated figure, ask us to confirm sizing against your application before ordering - we will check the datasheet with you.
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 rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the air demand of your equipment, and we will confirm the flow from the datasheet for this exact 1/4 in PT configuration on request.
This unit's bowl drains by differential pressure: as the filter element loads and the pressure difference across it grows, condensate is purged automatically - no daily manual draining. If you prefer, the same GFR200 body can be ordered with an automatic drain (code A) or a manual drain (code M); the manual-drain variant also widens the regulation range down to 0.05 MPa.
