The AirTAC GFR20008LC2 AirTAC Filter Regulator 1/4 in PT, 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 PT1/4" 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 GFR20008LC2 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single 200-size body with a PT1/4 (1/4 in) port. This configuration is the low-pressure regulator type, fitted with a 40 um standard filter element and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl is high enough. The bowl is polycarbonate (PC), and an external round gauge with a psi scale is fitted so the set pressure can be read directly. Maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT thread, and bracket or no bracket. Flow is published in the AirTAC catalogue as curves rather than a single rated figure; we 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. 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.

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.

Air-prepared supply for clamp cylinders on a machining or assembly fixture, where the low-pressure regulator type holds a gentle, repeatable clamp pressure and the 40 um element keeps debris out of the cylinder seals.
Clean, regulated air to diaphragm actuators on process valves in a plant where the control loop runs at modest pressures; the psi round gauge lets technicians verify the set pressure at the unit.
Supply to air cylinders operating diverters, pushers and gate stops on a packaging conveyor, with the differential-pressure drain keeping condensate out of the valves during continuous shifts.
Start with the port step: this unit is 200 size with a 1/4 in PT port, so match it to the air line and the flow your actuators actually consume - stepping up to a 300 or 400 size gives a larger port and more flow capacity. The low-pressure regulator type in this code is intended where the working pressure sits below the span of a standard regulator; the exact adjustment range for the low-pressure type is not published as a single figure, so ask us to confirm it against your setpoint before ordering. The differential-pressure drain is the default: it needs no daily manual action, but for very low or intermittent flow a manual (M) or automatic (A) drain may suit better. Filtration is the 40 um standard element; choose the W code for 5 um where finer protection is needed. This unit reads pressure on a round gauge with a psi scale; square embedded gauges and MPa or bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options, and the mounting bracket is included. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes G-series flow as curves in the catalogue, not as a single rated number, so we do not quote a flow figure for this unit. Send us your line size and the air consumption of the equipment it will supply, and we will confirm the flow data from the datasheet for the GFR200 size before you order.
The L in this code marks the low-pressure regulator type, intended for applications where the working pressure is below the span of the standard GFR regulator. Its exact adjustment range is not published as a single figure, so confirm it with us against your setpoint. The fitted round gauge has a psi scale so the set pressure can be read directly.
