The AirTAC GFR600C20MC2GK 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 See datasheet 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 GFR600C20MC2GK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit carries a G3/4 (BSPP) port, the largest port step in the GFR range, and is built for high-flow supply headers and main-line air preparation. It is fitted with a manual drain (code M), so accumulated condensate is released by opening the drain at the base of the bowl during routine checks. The 40 um standard filter element handles general-purpose particulate removal, and the manual-drain construction gives a wider regulation window of 0.05-0.9 MPa (7-130 psi). Per the code, this configuration includes a round psi-scale gauge, a reverse (check) valve (code K), and a mounting bracket. The maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C, non-freezing. Because this is the 600 size, the bowl is aluminium alloy rather than the polycarbonate used on the 200/300/400 sizes.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, thread options PT (standard), G and NPT, drain choices of differential-pressure, automatic or manual, a 5 um fine-filtration option (code W), and gauge, bracket and check-valve options. Flow for GFR units is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow figures for your application on request.

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 0.15 - 0.9 MPa (20 - 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.

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.

Conditioning and regulating the compressed air feeding a paint-shop distribution header, where water and particulate must be stripped before air reaches spray equipment and the 3/4 in G-thread port matches the main-line pipework.
Supplying filtered, regulated air to the pneumatic cylinders and grippers that index and stop bottles on a filling-line conveyor, with the manual drain opened during scheduled line sanitation rounds.
Feeding a stamping-press clamping and fixture circuit where a stable regulated supply holds workpieces, and the fitted check valve and bracket suit a fixed panel-mounted installation point.
Choose the size and port step against the air demand of the circuit: this GFR600 unit is the 3/4 in G-thread step, intended where a smaller 300/400 unit would restrict flow - size up rather than guess, and we will confirm flow against the published curves before you order. Drain type is a real choice: manual (as here) suits installations with scheduled maintenance visits and gives the wider 0.05-0.9 MPa (7-130 psi) regulation range, while the differential-pressure default drains automatically across a pressure band and the automatic option drains continuously. The 40 um element fitted here is the standard grade; specify 5 um (code W) only where downstream equipment needs finer filtration. Gauge scale is selectable (MPa, psi or bar) - this unit carries the round psi-scale gauge - and the fitted check valve (K) and included bracket complete the configuration. Thread is G (BSPP) here; PT is the catalogue standard with G and NPT as order options, so match the thread to your pipework, not to delivery expectations.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for GFR filter regulators as performance curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the flow figures from the datasheet on request, so you can size the 3/4 in G-thread unit against your actual air demand before ordering.
The M code in GFR600C20MC2GK specifies a manual drain: condensate collected in the aluminium alloy bowl is released by opening the drain fitting during routine checks, rather than automatically. Manual-drain GFR units carry a regulation range of 0.05-0.9 MPa (7-130 psi), wider than the 0.15-0.9 MPa (20-130 psi) window of the differential-pressure-drain versions, so choose manual drain where scheduled maintenance is practical and the lower setpoints matter.
