The AirTAC GFR20008MJC2WT AirTAC Filter Regulator NPT1/4 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 PT1/4" 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 GFR series combines filtration and pressure regulation in a single body: air passes through a drain bowl that removes water and particulate, then through a pressure-reducing valve, so one 1/4 in unit does both jobs. This configuration, GFR20008MJC2WT, is the size 200 body with a 1/4 in NPT port, a fine 5 um filter element (the W option; 40 um is standard), a manual drain on the polycarbonate bowl, a round pressure gauge reading in psi, the standard regulator type, and no mounting bracket or reverse/check valve. With the manual drain you periodically open the drain at the bottom of the bowl to expel collected condensate, which suits supervised installations where someone checks the bowl as part of routine rounds. The regulator adjusts from 0.05 to 0.9 MPa (7 to 130 psi), 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 filter-regulator family is available in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as orderable options, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, and gauge options with MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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.

Mounted at the air-preparation point of a cartoning or case-packing machine, this unit filters the shop air to 5 um and holds a fixed regulated pressure to the machine's pneumatic cylinders, with the psi gauge giving operators a quick visual check and the manual drain emptied during shift start-up rounds.
On a bench or panel feeding pneumatic lab apparatus, transducers and small actuators, the 5 um element keeps fine debris out of sensitive devices while the regulator sets the low working pressure the equipment needs, read directly off the round psi gauge.
Feeding the clamp and fixture actuators on a CNC or manual machining cell, this 1/4 in unit regulates clamping pressure to a repeatable setpoint, filters chips-laden shop air down to 5 um before the directional valves, and its manual drain is bled at the start of each shift as part of normal machine checks.
Start with the port step: this unit is the size 200 body on a 1/4 in NPT port; if your line needs more flow capacity, step up to size 300, 400 or 600 with the matching larger port. Choose the drain to match supervision: manual (this unit) for attended cells, automatic or differential-pressure for unattended duty. Choose the filter grade to match the downstream equipment: 40 um for general cylinders and valves, 5 um (this unit's W element) for finer instrumentation and pilot-air circuits. The round gauge fitted here reads in psi; embedded square gauges and MPa or bar scales are the other options. Thread is NPT on this unit; PT is the catalogue standard and G (BSPP) is also available. A mounting bracket can be specified instead of the no-bracket J option on this unit. For sizing, note that flow is published as curves, not a single rating, so send us your application and we will confirm the figures against the datasheet 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 number, so we do not quote a rated flow, Cv or SCFM figure for this unit. Send us your application details and we will confirm the relevant flow figures from the datasheet so you can size the unit against your demand before ordering.
The M in the code selects the manual drain on the filter bowl: instead of an automatic or differential-pressure drain, someone opens the drain at the bottom of the bowl to expel collected water. It suits attended installations on a maintenance round. If your installation runs unattended, ask us about the same GFR200-08 configuration with an automatic or differential-pressure drain instead.
