The AirTAC AirTAC GFR200-08 Filter Regulator, G1/4, 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 AirTAC GFR200-08 is a genuine AirTAC filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This 200-size unit is fitted with a G1/4 (BSPP) port, a manual drain bowl in polycarbonate, a standard 40 um filter element, and an embedded square gauge reading in psi. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR200 series. The G-series spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, drain choices (manual, automatic or differential-pressure), an optional 5 um element (code W), gauge scales in MPa, psi or bar, and G or NPT thread variants. Flow is published as curves rather than a single rating, so ask us to confirm 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.

On a CNC machining cell with air-actuated clamps and vises, this unit filters plant air to 40 um and holds a steady regulated pressure to the clamp cylinders, with the psi gauge letting the setter verify setpoint at the panel and the manual drain bled at shift start.
Filling, sealing and cartoning machines run banks of small air cylinders and valves that behave inconsistently on unregulated supply. A GFR200-08 at each machine's air inlet cleans the air and gives the machine its own set pressure, readable on the square psi gauge without opening the enclosure.
Sorting lines using air-jet diverters and pop-up stops depend on stable supply pressure to act at the right moment. Mounted at the station drop with its included bracket, this filter regulator keeps water and debris out of the jets while the regulator holds the pressure the diverter valves were set up for.
Start with the port step: the 200 size takes a 1/4 in port, and stepping up to GFR300, GFR400 or GFR600 buys larger ports and higher flow capacity - match the size to the air demand of the circuit rather than oversizing on guesswork. Because this unit has a manual drain, plan for someone to bleed the bowl periodically; if unattended drainage matters, the automatic (code A) or differential-pressure (blank) drain variants are the alternatives. The standard 40 um element suits general plant air; specify the W code for a 5 um element where finer filtration is needed. The fitted square gauge reads in psi (scales 1/2/3 give MPa, psi or bar), and the mounting bracket is included. Thread here is G (BSPP); PT is the catalogue standard and G/NPT are order options. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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 this series as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and air consumption, and we will confirm the flow from the datasheet and check the 200 size is right for your application before you order.
The M in the code means the polycarbonate bowl is drained by hand: open the drain valve periodically to expel collected water. If you cannot guarantee that routine, the same GFR200-08 body is available with an automatic drain (code A) or a differential-pressure drain (no letter), which discharge condensate without operator intervention.
