The AirTAC GFR400C15MC2TK AirTAC Filter Regulator NPT1/2 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 GFR400C15MC2TK is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is threaded NPT1/2 (1/2 in), carries a 40 um standard filter element, and drains by hand via the manual drain on the bowl, so moisture is released when an operator opens the drain rather than automatically. The K code adds a reverse (check) valve, the J position is absent so a mounting bracket is included, and pressure is read on the fitted round gauge scaled in psi. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.05-0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl on this size is polycarbonate (PC).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, an optional 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads as order options alongside the PT standard. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

Point-of-use clean-up and pressure setting on the air feed to a paint mixing room, where water and pipe scale must be stripped out and atomizing pressure held steady before the spray equipment.
Conditioning the air feed to the pneumatic cylinders and flap-fold actuators on a carton erector and taper, with the manual drain bled at shift start and the psi gauge set for the machine's supply pressure.
Filtering and regulating shop air on a bench that pressure-cycles pneumatic components, where the check valve holds the set circuit and the round psi gauge gives a direct reading during tests.
Size 400 with a 1/2 in port sits in the upper half of the GFR range; step up to size 600 or down to size 300 depending on the flow your line needs - we will check the published flow curves against your application on request. This unit has a manual drain, which suits installations where an operator can regularly bleed the bowl; choose the automatic or differential-pressure drain versions if the unit is mounted in a hard-to-reach spot. The 40 um element is the standard grade; specify the W variant if you need 5 um filtration. The round gauge here reads in psi; square gauges and MPa or bar scales are also available. Thread is NPT on this code, with G (BSPP) and PT available to order. A bracket is included, and the K code means a reverse/check valve is already fitted.
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 curves, not as a single rated number, so there is no one figure we can honestly quote. Tell us your application and we will confirm the relevant flow and datasheet figures on request before you order.
The M in the code specifies a manual drain: moisture collected in the bowl is released by hand, which suits accessible installations on a regular maintenance round. The same size 400 filter regulator is available with an automatic drain (code A) or the default differential-pressure drain if you prefer not to rely on manual bleeding.
