The AirTAC GFR200-08 AirTAC Filter Regulator, PT1/4, 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 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 GFR200-08 is a filter regulator: it removes water and particulate from compressed air and controls downstream pressure in a single compact body. This 200-size unit is fitted with a PT1/4 (1/4 in) port, the standard 40 um filter element, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element rises. It is the low-pressure type, so it is intended for circuits that hold a lower regulated pressure than a standard unit is set up for. An external round gauge with a psi scale is fitted so operators can read the set pressure directly, a reverse/check valve is built in to hold downstream pressure if the supply drops, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with a choice of ports, PT/G/NPT threads, drain types, 40 um or 5 um filtration, gauge styles and scales, and low-pressure or standard regulation. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. 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.

On a CNC fixture line, clamps and swing cylinders need clean, dry air held at a steady, lower-than-supply pressure. The GFR200-08 filters the supply, regulates it down with its low-pressure type setting, and the check valve holds the clamp circuit if the main supply dips mid-cycle.
A cartoning or wrapping machine's valve island needs particulate- and water-free air at a stable setpoint. This unit conditions the 1/4 in branch feeding the island, the psi gauge lets the technician verify the setpoint, and the differential-pressure drain keeps condensate out of the valves.
A robot cell's gripper and pick-and-place actuators run on instrument-quality air at a reduced pressure. The 40 um element protects the small control valves, the regulator holds the grip pressure steady, and the included bracket mounts the unit neatly on the cell's prep panel.
Start with the port step: the 200 size carries the 1/4 in port in this code, and larger sizes (300/400/600) move up in port and flow capacity - pick the size against the air demand of the circuit, and we will confirm the flow curve before you order. This unit uses the default differential-pressure drain, which suits a continuously running line; if the machine runs intermittently, an automatic (A) or manual (M) drain may suit better. Filtration is the standard 40 um grade, which protects most downstream valves and cylinders; specify the W code for 5 um where finer protection is needed. The round gauge fitted here reads in psi; square embedded gauges and MPa/bar scales are the other options. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options. A bracket is included, and the K code confirms the reverse/check valve is fitted.
Because flow is published as curves rather than a single rated figure, please ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow 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 required air demand, and we will confirm the flow curve and correct size from the datasheet before you order.
The L code means this GFR is the low-pressure type of regulator, intended for circuits regulated below the standard unit's normal setting; the exact adjustment range for the low-pressure type is not published in our sheet, so ask us to confirm it on request. The K code means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply is lost. This unit also carries an external round gauge reading in psi and a differential-pressure drain.
