The AirTAC AirTAC GFR20006LC3WTK Filter Regulator NPT 1/8 in 5 um 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 GFR20006LC3WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This size 200 unit is ordered with a 1/8 in NPT port, a 5 um filter element (code W, finer than the 40 um standard), a low-pressure regulator type, a differential-pressure drain, a round pressure gauge with bar scale, a reverse/check valve, and a mounting bracket. The polycarbonate bowl lets you see accumulated condensate at a glance, and the differential-pressure drain discharges it automatically when the pressure differential calls for it. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT as catalogue options), low-pressure type, reverse valve and bracket. Flow is published as curves rather than a single rating, so we confirm flow and datasheet figures on request - just ask before ordering.

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.

| 06 | Port size PT1/8". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |

| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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.

Point-of-use conditioning ahead of a directional control valve: the 5 um element keeps fine particulate out of the valve spool while the low-pressure regulator holds a gentle, stable supply pressure to the actuator.
Feeding light-duty screwdrivers, riveters and air cylinders at a compact assembly station, where the 1/8 in NPT port matches short drop lines and the round bar gauge gives the operator a visible set point.
Conditioning and trimming supply pressure on a bench-top test rig or lab apparatus, where the fine 5 um grade protects sensitive instrumentation and the reverse/check valve holds the line if upstream supply dips.
Start with the port step: size 200 with a 1/8 in NPT port suits the smallest branch lines; step up through sizes 300, 400 and 600 as your line size and air demand grow. This unit carries the 5 um element (code W) - choose it where finer particulate removal matters, or order the 40 um standard grade for general-duty protection. The low-pressure regulator type is intended for lower set-point work; its exact adjustment range is not published, so confirm it against your set pressure before ordering.
Other decodable choices: the differential-pressure drain here discharges condensate automatically as the pressure differential builds, with manual-drain and automatic-drain variants available in the family; the round gauge is fitted with a bar scale, and square embedded gauges with MPa, psi or bar scales are the catalogue alternatives; thread is NPT here, with PT as the standard and G (BSPP) as an option; and the bracket is included. Flow is published as curves, not a single rated figure, so ask us to confirm sizing against your application 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 curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet curves and check the sizing against your application before you order.
The C in the code orders the optional external round pressure gauge, and the 3 sets its scale to bar. The embedded square gauge is the catalogue standard, with MPa, psi or bar scales available. If you prefer a different gauge style or scale on the GFR200, we can quote the matching catalogue variant.
