The AirTAC GFR20008MLJF2K AirTAC Filter Regulator PT1/4, 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 series combines water and particulate filtration with pressure regulation in a single compact body, so one 1/4 in (PT1/4) connection does both jobs. This configuration, GFR20008MLJF2K, is the low-pressure regulator type with a manual drain bowl in polycarbonate, a 40 um standard filter element, an embedded square gauge scaled in psi, and a built-in reverse/check valve. The manual drain means an operator opens the bowl drain to expel collected condensate, which suits lines that are checked as part of a routine walk-round. It ships without a mounting bracket, so plan to mount it inline or on your own bracketry.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options including automatic or differential-pressure drains, a 5 um (W) element, G or NPT threads, and gauge scale choices. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application before you order.

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.

On a machining cell where pneumatic clamps and swing cylinders run at reduced pressure to protect delicate workpieces, this filter regulator cleans the supply of water and swarf and holds the set pressure, with the psi gauge giving the operator a direct readout at the fixture.
Packaging lines with pneumatic flap folders, case erectors and tape heads benefit from a single-body filter regulator at the machine drop: the 40 um element stops particulate reaching directional valves, the manual drain is emptied during shift changeover, and the check valve holds the setpoint if the main supply dips.
Test benches and laboratory rigs that feed air to instruments or low-pressure actuators need clean, gently regulated air. The low-pressure regulator type, square psi gauge and reverse/check valve let a technician set and watch a stable supply pressure while the polycarbonate bowl shows condensate at a glance.
Start with the port step: size 200 with 1/4 in ports is the entry point of the GFR range, and stepping up to 300, 400 or 600 buys larger ports and more flow capacity. Because this is the low-pressure regulator type, confirm the working pressure of your circuit with us before ordering so the adjustment range matches. Choose the drain to match your maintenance routine: manual (this unit) needs a scheduled bleed, while automatic and differential-pressure drains handle condensate without operator action. The 40 um element is the standard grade; specify the W code for 5 um if finer filtration is needed. The embedded square gauge here reads in psi; MPa and bar scales are available, and an external round gauge is optional. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and brackets can be added if you want panel mounting. Flow is published as curves, not a single rating, so send us your application details 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. 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 performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your line pressure and the air demand of your equipment, and we will confirm the sizing from the datasheet curves on request before you order.
The M in the code GFR20008MLJF2K specifies a manual drain: an operator opens the bowl drain to remove collected condensate, which suits installations visited during routine checks. If you prefer hands-off condensate removal, the same GFR200 body is available with an automatic drain (code A) or the differential-pressure drain that is the series default - just ask for the alternative model code.
