The AirTAC GFR400C10AJC2 AirTAC Filter Regulator PT3/8 Auto Drain 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 GFR400C10AJC2 is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a PT3/8 (3/8 in) port, a 40 um standard filter element, and an automatic drain that expels collected condensate without manual attention. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and the fitted external round gauge reads in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The size 400 bowl is PC (polycarbonate), and this unit is ordered without a mounting bracket.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um (code W) element option, embedded square or external round gauges with MPa, psi or bar scales, G or NPT thread variants, and bracket choices. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

Filtered and regulated air feeding the directional control valves on a carton-forming and taping machine, with the automatic drain keeping condensate out of the valve bank during continuous shifts.
Supply point for the pneumatic stoppers and pusher cylinders along a bottling conveyor, where the 3/8 in port and set-and-hold regulation keep actuator pressure stable line-wide.
Air preparation for the clamping cylinders on a machining-centre fixture, with the 40 um element protecting the clamping valves and the psi gauge giving operators a direct setpoint readout.
Start with the port and size: this unit is the size 400 body with a PT3/8 (3/8 in) port, the step to choose when your line flow sits above what a 300-size body handles and below the 600 frame. Larger sizes carry larger ports and more flow. The drain here is automatic, which suits unattended installations; differential-pressure drain is the default alternative and manual drain suits periodically serviced points. The 40 um element is the standard grade for general pneumatic supply; specify the W code for a 5 um element if downstream equipment needs finer filtration. The fitted round gauge reads psi; square embedded gauges and MPa or bar scales are available. Thread is PT as standard, with G (BSPP) and NPT as order options, and brackets are optional (this unit is ordered without one). Flow is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet 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 flow for the GFR series as performance curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow curve and sizing from the datasheet on request before you order.
The A in the code sets the automatic drain: collected condensate is expelled without operator attention, which suits unattended or hard-to-reach installations. The family also offers differential-pressure drain (the default) and manual drain (code M) as alternative configurations, and a 5 um filter element is available under the W code.
