The AirTAC GFR600-20 AirTAC Filter Regulator PT3/4, 5 um, Manual Drain 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 PT3/4" 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 GFR600-20 is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size-600 unit carries a 3/4 in PT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain on the bowl, and a reverse/check valve. Because it is the 600 size, the bowl is aluminium alloy rather than polycarbonate. The regulator is the low-pressure type and the unit is fitted with an external round gauge reading in psi; a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is published 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 form and bracket. 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. 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.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| 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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeding the pneumatic cylinders and clamps on a cartoning or case-packing line: the 5 um element catches water and fine particulate before the actuators, and the low-pressure regulator holds a gentle, stable supply pressure for delicate sealing and folding motions.
Supplying spray guns and air-assist lines in a furniture finishing shop, where clean, dry, finely regulated low-pressure air keeps finish quality consistent and the manual drain fits the end-of-shift blowdown routine.
On weaving and spinning frames that use air jets and pneumatic thread guides, this unit filters the mill's compressed air to 5 um and regulates it to the low pressures those delicate mechanisms need, with the psi gauge giving operators a familiar readout.
Step through the decodable choices in this order. First size and port: 200/300/400/600 step up in port and flow capacity, and this unit is the largest, 3/4 in PT. Second, drain: manual drain means someone opens the drain at the bowl, versus automatic or differential-pressure drain; manual is often chosen where a scheduled check fits the maintenance routine. Third, filter grade: 40 um is standard and 5 um (code W, as here) is the finer option for sensitive downstream equipment. Fourth, gauge: this unit has an external round gauge on a psi scale; square embedded gauges and MPa or bar scales are the other catalogue options. Thread is PT as standard, with G (BSPP) and NPT available to order. A bracket is included. The regulator here is the low-pressure type; its exact adjustment range is not published in the material we hold, so ask us to confirm it from the datasheet. Because flow is published as curves and not a single rating, send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. 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 rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your required flow and working pressure and we will confirm the sizing from the datasheet for your application before you order.
The M in the code GFR600-20MLC2WK selects a manual drain: condensate collected in the bowl is released by hand, which suits installations with a scheduled maintenance check. The catalogue also offers automatic drain (code A) and differential-pressure drain (the default, no code) if you would rather not rely on manual operation.
