The AirTAC GFR20008MLF1T 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 one compact body, so a single 200-size unit does both jobs at the 1/4 in port. This configuration is the low-pressure type with a manual drain bowl, a 40 um standard filtration element, an embedded square pressure gauge scaled in MPa, and NPT threads. The manual drain means an operator opens the bowl drain to discharge collected condensate, which suits installations checked as part of a routine walk-round. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, a 5 um element option (code W), square or round gauges with MPa, psi or bar scales, and G (BSPP), NPT or PT threads. We confirm flow and datasheet figures on request, as flow 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. 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.

A filtered, regulated supply at the panel inlet protects directional valves and I/P components on a packaging or assembly machine, with the square MPa gauge giving the operator a visible setpoint. The low-pressure type suits circuits designed to run below standard line pressure.
On a bottling or food-handling conveyor, this unit feeds air cylinders and cleaning nozzles from a 1/4 in drop leg. The 40 um element catches pipe scale and the manual drain bowl is emptied during the shift changeover check.
Bench rigs and small test stations need clean air trimmed to a stable, lower-than-line pressure. The low-pressure regulator type, compact 200-size body and NPT1/4 connection make this a straightforward drop-in supply unit, with the gauge confirming the set pressure at a glance.
Size and port are the first choice: the 200 size at 1/4 in NPT is the compact step in the GFR range, and the larger 300/400/600 sizes carry bigger ports and more flow, so match the size to the air demand of the circuit rather than only to the pipe. Drain type matters in service: manual drain (this unit) needs someone to open the bowl, automatic drain discharges on its own, and differential-pressure drain is the default behaviour. Filtration is 40 um standard; choose the 5 um W option where downstream equipment needs finer protection. Gauge scale (MPa, psi or bar), thread (PT standard, G and NPT to order) and bracket are the remaining decodable choices.
Flow for this family is published as curves, not a single rated figure, so we do not quote a number here. Ask us to confirm sizing against your application and we will read the datasheet curve for the GFR200 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 the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and required flow, and we will confirm the correct size from the GFR200 datasheet curve on request before you order.
The M in the code selects a manual drain bowl: collected condensate is released by opening the drain when checked, rather than discharging automatically. It suits installations visited regularly. If nobody will open the drain, choose the automatic (A) or differential-pressure (blank) drain variant of the same GFR200 size.
