The AirTAC GFR200-08 AirTAC Filter Regulator PT1/4, 40 um, Round 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 compact filter regulator that removes water and particulate from compressed air and holds downstream pressure steady in a single body. This 200-size unit is fitted with a 1/4 in PT port, the standard 40 um filter element, and a differential-pressure drain that automatically bleeds collected condensate when the pressure differential across the element rises. The built-in regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and this configuration carries an external round gauge reading in psi plus a reverse/check valve that helps hold the set pressure if upstream supply drops. The polycarbonate bowl suits the 200 frame, and the unit is ordered without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, optional 5 um filtration, automatic or manual drains, and G or NPT thread variants. 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.

Filtered, regulated air to clamping cylinders on a production fixture, with the check valve helping hold the set clamp pressure if the main supply dips mid-cycle.
Clean, pressure-stable air for diverters, sealers and pusher cylinders on a packaging conveyor, with the differential-pressure drain handling condensate without operator attention.
Point-of-use filtration and regulation ahead of grippers and auxiliary actuators in a robot cell, with the round psi gauge giving operators a clear local setpoint reading.
Start with the port step: the 200 size takes a 1/4 in PT connection, and larger GFR sizes (300/400/600) step up in port and flow capacity, so size the frame against the air demand of the circuit rather than the pipe alone. Choose the drain to match access: this unit's differential-pressure drain needs no attention, while automatic (code A) and manual (code M) versions are catalogue options. The standard element is 40 um; specify W for 5 um where finer filtration is needed. Gauge style and scale are decodable - this code's C2 gives an external round gauge in psi, and MPa or bar scales are alternatives. Thread is PT as standard; G (BSPP) and NPT are order options, as are bracket (J omits it) and the reverse/check valve (K, fitted here).
Flow for the GFR series is published as curves, not a single rated figure, 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. 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 figure, so we do not quote one number. Tell us your application's air demand and we will confirm the correct size and flow from the datasheet on request.
C is the external round gauge, 2 sets its scale to psi, and K means a reverse/check valve is fitted. The blank drain position is the differential-pressure drain, and J means the unit is supplied without a mounting bracket.
