The AirTAC GFR20008LJC3TK 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 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 GFR20008LJC3TK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This unit is built on the size-200 frame with 1/4 in NPT ports and is the low-pressure (L) regulator type. It carries the standard 40 um filter element and a differential-pressure drain, which discharges collected condensate when the pressure differential across it calls for it. An external round gauge scaled in bar is fitted, and the K code adds a reverse (check) valve that helps hold downstream pressure if the supply drops. No mounting bracket is included with this configuration.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and can be ordered with automatic or manual drains, a finer 5 um (W) filter element, different gauge styles and scales, G (BSPP) or NPT threads, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application 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.

|---|---|
| 08 | Port size PT1/4". 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Filtered, regulated air to the taping heads and hold-down cylinders on a packaging line, with the fitted check valve holding cylinder position if plant air pressure dips.
Low-pressure clamping circuits on machining and assembly fixtures, where the regulator holds a gentle, repeatable clamp force and the check valve keeps the clamp from relaxing on a supply drop.
Point-of-use air preparation for paint and coating spray guns, where the 40 um element catches pipe scale and water before it can reach the finish.
Choose the size by port and flow: this unit is size 200 with 1/4 in NPT ports, the smallest GFR frame; step up to 300, 400 or 600 for larger ports and higher flow. The L code makes this the low-pressure regulator type, suited to circuits that run below standard working pressures - the exact adjustment range is not published in the data we hold, so confirm it with us. The 40 um element is the standard grade; a 5 um element (code W) is available if finer filtration is needed.
The drain here is differential-pressure; automatic (A) and manual (M) drains can be ordered instead. This configuration has a round gauge scaled in bar and a fitted check valve, and no bracket - a bracket can be added at order. The thread is NPT here; G (BSPP) and PT are the other catalogue options. Flow is published as curves, not a single rating, so send us your flow and pressure requirements 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm the datasheet figures for the GFR20008LJC3TK before you order.
K means a reverse (check) valve is fitted, which helps hold downstream pressure when the upstream supply drops - useful on clamping or holding circuits. L marks the low-pressure regulator type; its exact adjustment range is not published in the data we hold, so confirm it with us.
