The AirTAC GFR60020MC2GK AirTAC Filter Regulator G3/4, Manual Drain 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 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 GFR60020MC2GK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit carries a G3/4 (BSPP) thread, uses the standard 40 um filter element, and is fitted with a manual drain, a round psi gauge and a reverse (check) valve. The aluminium alloy bowl suits the larger 600 frame, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, plus options for 5 um filtration, automatic or differential-pressure drains, gauge scale and thread type. Maximum inlet pressure is 1.0 MPa (145 psi), working temperature is -5 to 70 C (non-freezing), and the standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet for your application.

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.

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Feeding spray guns and booth air drops on a paint line, where particle-free air held at a set pressure protects finish quality; the 40 um element and steady regulation do that job at the 3/4 in main.
Supplying fixture and clamp cylinders on a machining centre, where the regulator holds consistent clamping force and the check valve helps hold the set pressure if the supply dips.
Powering carton-forming and sealing cylinders on a packaging conveyor, with filtered, regulated air from the 3/4 in header and a manual drain for the daily end-of-shift blowdown.
Size and port set the air capacity: 600 is the largest GFR frame, here with a 3/4 in G thread - step up or down a size if your line needs more or less flow. Choose the drain to match attendance: manual (this unit) needs periodic draining by hand, automatic suits unattended drops, and differential-pressure drains with the pressure drop across the element. The standard element is 40 um; order the W code for 5 um when finer filtration matters. Gauge scale (MPa, psi or bar - this unit is psi, round type), thread (PT is the standard; G or NPT are order options) and the fitted check valve are all decodable choices. Because flow is published as curves, not a single rating, send us your demand 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 GFR600 as curves, not a single rated figure, so we do not quote a number. Tell us your demand and conditions and we will confirm the relevant figure from the datasheet before you order.
The M code means the aluminium alloy bowl is drained by hand: open the drain periodically to purge collected water. If this unit sits where nobody passes, the same GFR600 body is available with an automatic or a differential-pressure drain - just pick that code.
