The AirTAC GFR20006LNWT AirTAC Filter Regulator, 1/8 in NPT is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/8" 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 GFR20006LNWT is a size 200 GFR filter regulator: a single body that first removes water and particulate from compressed air, then holds the downstream pressure at your setpoint. This configuration is built with a 1/8 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and the low-pressure regulator type for circuits that run at reduced setpoints. No gauge is fitted on this variant, and the polycarbonate bowl suits the non-freezing -5 to 70 C operating range with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes stepping up from 1/8 in to 1 in, and options including 40 um or 5 um elements, differential-pressure, automatic or manual drains, gauges with MPa, psi or bar scales, and PT, G or NPT threads. Published flow data for this series is given as curves rather than a single rating, so we confirm the datasheet figures for your application 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.

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 milling cell, this unit cleans the shop air feeding the clamping fixtures and holds a steady reduced pressure so workpieces are gripped consistently without over-pressuring small-bore cylinders.
On a carton packaging line with vacuum and gripper cylinders, the 5 um element keeps moisture and fine particles out of the directional valves, while the regulator holds the low setpoint the grippers were designed for.
At a spray-painting booth, this unit strips water and 5 um-scale particulates from the supply and regulates a gentle, stable pressure to the atomising circuit, protecting finish quality on each panel.
Start with the port and size: the 200 frame with a 1/8 in NPT port is the smallest step in the GFR range, so match it against the air consumption of the circuit it feeds - and because flow is published as curves rather than a single rating, ask us to confirm sizing before ordering. The 5 um element here is the finer choice; the standard grade is 40 um, so pick 5 um where downstream valves or instruments need cleaner air. Drain choice is differential-pressure on this unit, with automatic and manual drains available as alternatives in the series. Gauges (square embedded or external round, in MPa, psi or bar scales) are options you can add to other GFR variants; this code specifies none. Threads come as PT (standard), G or NPT, and a mounting bracket is included with this unit.
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. Send us your application details and we will confirm the flow and datasheet figures for this exact configuration on request.
The W in the code GFR20006LNWT selects the 5 um element, the finer of the two catalogue grades, suited to circuits with sensitive valves or instruments. The standard grade is 40 um, which is the usual choice for general plant air where finer filtration is not required.
