The AirTAC GFR600C20MLC2WGK AirTAC Filter Regulator G3/4, 5 um 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 AirTAC GFR600C20MLC2WGK is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in one body, with a G3/4 (BSPP) port. This configuration carries the 5 um filter element (code W) for finer air cleaning than the standard 40 um grade, a manual drain for controlled bowl purging, and the low-pressure regulator type for circuits that run below standard regulating ranges. It is fitted with an external round gauge scaled in psi, a reverse/check valve (code K), and a mounting bracket. As a size-600 unit, the bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um filtration, standard or low-pressure regulation, gauge style and scale options, and G, NPT or PT threads. Because AirTAC publishes flow only as curves rather than a single rating, we confirm the exact flow and datasheet 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.

Feeds filtered, regulated air to the clamp and fold cylinders on a carton-forming and wrapping line, with the 5 um element protecting valve spools from particulate carryover and the round psi gauge giving operators a visible setpoint at the machine.
Serves as the conditioning point for a robotic assembly cell where pick-and-place actuators and air-driven tooling run at reduced pressure, combining filtration and regulation in one body to save panel space on the cell's service manifold.
Installed at a machine-shop air drop serving pneumatic clamping fixtures and air vices, where the manual drain suits a station that is bled down at shift end and the check valve holds the downstream circuit if upstream supply is interrupted.
Size and port are the first decision: the G-series steps through sizes 200, 300, 400 and 600, with larger sizes carrying larger ports and more flow, so match the size to the air demand of the circuit rather than to the pipe alone. This unit is already the top of the range at size 600 with a G3/4 port. Drain type is a real choice: manual drain (as here) means an operator purges the bowl, while automatic and differential-pressure drains discharge condensate without attention - pick manual where visits to the unit are already part of the routine. Filter grade is 40 um standard or 5 um with the W code; this unit carries the finer 5 um element, which suits downstream equipment that tolerates less particulate. Note that the regulator is the low-pressure type, so confirm its exact adjustment range with us before ordering if your setpoint is not clearly a low-pressure one.
Thread is G (BSPP) on this unit; PT is the catalogue standard and G or NPT are order options, so match the thread to your pipework. Gauge style is embedded square as standard with an external round gauge optional, scaled in MPa, psi or bar - this unit has the round gauge in psi. A mounting bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before you order.
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 the GFR series as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
The M in the code specifies a manual drain: condensate is purged by opening the drain when servicing the unit. The GFR family also offers automatic (code A) and differential-pressure (blank) drains that discharge condensate without operator attention, so if the unit will be installed where regular purging is impractical, ask us to quote the automatic-drain variant instead.
