The AirTAC GFR200-08 AirTAC Filter Regulator, NPT1/4, Low-Pressure 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 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 1/4 in NPT ports, a manual drain on the polycarbonate bowl, a 40 um standard filter element, and a low-pressure regulator type for circuits that run below standard working pressures. It comes with an embedded square gauge scaled in bar, a built-in reverse/check valve, and a mounting bracket, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the G-series range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so we confirm the datasheet and sizing figures 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Feeds and regulates the air supply to clamp cylinders on a CNC fixture, where the low-pressure regulator type holds a gentle, repeatable clamp force and the 40 um element keeps water and chips-carried debris out of the valve stack.
Conditions the supply to a bench-top test rig or pilot rig that runs at reduced pressure, with the bar-scaled square gauge giving a clear local reading and the manual drain letting the technician bleed the bowl at the end of each session.
Sits ahead of the directional valves on a packaging machine's low-pressure actuator circuit, filtering the shop air and regulating it to the setting the cylinders were designed for, with the check valve holding the downstream setting if the supply dips.
Size the unit by the port and body step: 200 is the compact entry size with a 1/4 in port here, and the series steps up through 300, 400 and 600 as flow demand grows. This configuration carries a manual drain, which suits installations where an operator can bleed the bowl on a routine basis; automatic and differential-pressure drains are available if the unit will be left unattended. The 40 um element is the standard grade, with a 5 um (W) element offered where finer particulate removal is needed. The embedded square gauge is scaled in bar here, with MPa and psi scales available, and an external round gauge is an option. Thread is NPT on this unit; PT is the catalogue standard and G (BSPP) is also orderable. A mounting bracket is included.
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. The low-pressure regulator range for this type is not published in the standard table, so we will confirm the exact adjustment range on request as well.
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 G-series as curves rather than a single rated figure, so there is no one rated flow number we can honestly quote for this unit. Tell us your application and we will confirm the flow and sizing figures from the datasheet on request before you order.
The M in the code selects a manual drain: an operator opens the bowl drain to expel collected water, which suits attended installations; automatic and differential-pressure drains are catalogue alternatives for unattended duty. The L in the code selects the low-pressure regulator type, intended for circuits running below standard working pressures; its exact adjustment range is not published in the standard table, so we confirm it on request.
