The AirTAC GFR600C20LF2G AirTAC Filter Regulator, G3/4, Low Pressure 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 GFR600C20LF2G is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration carries a G3/4 port with G (BSPP) thread, a 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises. Regulation is the low-pressure type, suited to circuits that run well below standard line pressures; the exact regulation range for the low-pressure version is not published, so we confirm it against your setpoint on request. An embedded square gauge with a psi scale is fitted, the bowl is aluminium alloy (standard at size 600), a mounting bracket is included, and no reverse/check valve is fitted. 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. The GFR family spans sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch, G (BSPP) and NPT thread options, 40 um standard or 5 um (W) elements, automatic, manual or differential-pressure drains, standard or low-pressure regulation, square or external round gauges with MPa, psi or bar scales, and optional check valves. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow data 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 0.15 - 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.

Fixture clamping and workholding actuators that hold at a reduced setpoint benefit from a single body that cleans the supply air and regulates it down. The low-pressure regulation type and psi-reading square gauge let the setter dial in and watch the clamp pressure directly at the station.
Packaging lines feeding many valves and cylinders from one drop need clean, regulated air at the manifold inlet. A size 600 unit with a G3/4 port sits at the head of the manifold, the 40 um element stops particulate reaching the valves, and the differential-pressure drain handles condensate without daily attention.
Pilot-operated process valves and positioners need steady, filtered air at a modest pressure to shift reliably. This filter regulator conditions the pilot supply in one body, the low-pressure regulation type suits the modest setpoints pilots run at, and the aluminium alloy bowl with bracket gives a secure panel or frame mounting.
Size 600 with a G3/4 port is the largest step in the GFR range, so start by matching the port and body size to the air demand of the machine or line downstream - the larger the size, the larger the port and the greater the flow capacity. This unit is the low-pressure regulation type: choose it when your circuit holds a setpoint well below standard line pressure, and let us confirm the exact range against your required setting. The 40 um element is the standard grade for general plant air; specify the 5 um (W) element only where downstream equipment needs finer filtration. The differential-pressure drain is fitted here and needs no operator attention; a manual-drain version is available if you prefer scheduled draining, and an automatic float drain can be ordered. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is G (BSPP) on this code - PT is the standard thread and G or NPT are order options - and the mounting bracket is included. Flow for the GFR series is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing from the datasheet 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, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your line pressure, setpoint and air demand and we will confirm the flow data from the datasheet for this exact model before you order.
The L in the code marks the low-pressure regulation type, intended for circuits that hold a setpoint well below standard line pressures. AirTAC does not publish the regulation range for the low-pressure version, so we confirm the exact range against your required setting on request. The standard-type GFR units regulate 0.15-0.9 MPa (20-130 psi) with this drain configuration, if that range suits your application instead.
