The AirTAC GFR20008MLF2W AirTAC Filter Regulator 1/4 in, 5 um, Manual 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR20008MLF2W 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 fitted with a PT1/4 (1/4 in) port, a fine 5 um filter element for cleaner air than the standard 40 um grade, a manual drain for controlled bowl evacuation, and a low-pressure regulator type for circuits that run below standard working pressures. An embedded square gauge graduated in psi is included, the polycarbonate bowl suits the 200 size, and a mounting bracket ships with the unit. 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 filter-regulator family spans sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) filtration, gauge and scale options, and G (BSPP) or NPT threads as orderable alternatives to the PT standard. Flow figures for this model are published as curves rather than a single rating - 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.

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.

A light-duty bench press running at reduced circuit pressure takes filtered, regulated air from this unit: the 5 um element protects the press cylinder seals, the low-pressure regulator type suits the reduced working pressure, and the psi gauge lets the operator set and monitor the line at a glance.
On a carton-sealing or wrapping machine, this filter regulator conditions the supply feeding the clamp and flap-folding cylinders: water and fine particulate are stripped out at 5 um, pressure is held steady for consistent clamping, and the manual drain is emptied during scheduled changeover stops.
In the air-preparation panel of a small robotics pick-and-place cell, this unit filters and regulates the supply to the gripper and vacuum-generator circuit. The low-pressure regulator type matches the gentle working pressures grippers need, and the square psi gauge gives a clear panel-mounted reading.
Start with the port step: this unit is the 200 size with a PT1/4 (1/4 in) port; if your line needs more flow, the GFR300, GFR400 and GFR600 sizes step up in port and body size. Choose the drain to match maintenance access: manual drain (as fitted here) gives controlled evacuation, while automatic or differential-pressure drains suit installations that are not checked daily. The 5 um element in this code is the finer option over the 40 um standard - pick it when downstream valves and cylinders need cleaner air. The square gauge here reads in psi; MPa and bar scales are also available. Thread is PT as standard, with G (BSPP) and NPT offered as catalogue options, and the bracket is included (the J suffix would omit it). Flow is published as curves, not a single rating, so 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. 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 performance curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the relevant datasheet figures on request before you order.
The M in the code specifies a manual drain: you evacuate the bowl by hand at intervals, which suits stations that are checked regularly. The W in the code specifies the 5 um filter element, the finer option over the standard 40 um grade, giving cleaner air for sensitive downstream components.
