The AirTAC GFR200-08L AirTAC Low-Pressure Filter Regulator G1/4 is a genuine G-series filter regulator: water separation, 5 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 GFR200-08L is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This 200-size unit is ordered with a G1/4 (BSPP) port, the low-pressure type regulator for circuits that run below standard line pressure, a 5 um filter element (code W) for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, a round external pressure gauge scaled in psi, and a built-in reverse/check valve that holds downstream pressure if the supply drops. The polycarbonate bowl suits this size, and no mounting bracket is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/4 to 1 inch, and each size can be ordered with your choice of drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT as order options), bracket and check valve. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the 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. 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.

| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Filtering and regulating the pilot air feeding solenoid valves on a filling or capping station, where the low-pressure type regulator suits circuits running below standard plant pressure and the 5 um element protects sensitive valve internals.
Conditioning supply air to diverters, stoppers and pusher cylinders along a sorting conveyor, with the check valve holding actuator position if upstream supply is interrupted and the psi gauge giving operators a local pressure readout.
Supplying clean, regulated low-pressure air to bench-top test rigs and instrumentation panels, where the 5 um filtration grade, compact 1/4 inch port size and differential-pressure drain keep the circuit tidy without manual draining.
Start with the port step: the 200 size carries a 1/4 inch port, and larger sizes (300/400/600) step up in port and flow capacity - match the size to the air demand of the circuit rather than oversizing on guesswork. This unit is the low-pressure type (code L), intended for circuits that operate below standard regulator range; the exact adjustment range for the low-pressure type is not published in the summary data, so confirm it with us against your working pressure before ordering. The 5 um element (W) suits applications needing finer particulate removal than the 40 um standard; the differential-pressure drain needs no manual attention but relies on flow to purge condensate, so consider an automatic or manual drain variant for low-flow duty. The round gauge here is scaled in psi; square embedded gauges and MPa or bar scales are alternatives. Thread is G (BSPP) on this code, with PT as the standard and G/NPT as order options, and no mounting bracket is included (code J).
Because flow is published as curves rather than a single rated figure, we cannot quote one number here - send us your application details and we will confirm sizing against the datasheet curves before you order.
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 performance curves rather than a single rated figure, so we do not quote one number. Send us your application - working pressure, downstream demand and duty cycle - and we will confirm the relevant datasheet curve and sizing on request before you order.
The L code marks the low-pressure type regulator, intended for circuits that operate below the standard regulator range. The exact adjustment range for the low-pressure type is not published in the summary data, so please confirm it with us against your working pressure. The rest of the code decodes as: G1/4 port, no bracket, round psi gauge, 5 um element, G thread and a fitted reverse/check valve.
