About the Airtac GPF Oil Mist Separator GPF400C10AJM
The GPF400C10AJM is a GP-series oil mist separator from AirTAC that strips oil mist and fine particles from compressed air with a 0.3 um (M) coalescing element rated at 99.9% efficiency. It is piped through 3/8 in PT threaded ports and delivers a rated flow of 1100 L/min with 0.7 MPa at the inlet and 0.5 MPa at the outlet.
The C in the code selects the metal bowl, the toughest choice against the standard PC and nylon options, and the A option fits an automatic drain, so condensate is expelled without anyone opening the 89 cc bowl. The trailing J means this version ships without a mounting bracket, so plan to carry the weight of about 620 g on the pipework or supply your own bracket. Operating pressure is 0.15 to 1.0 MPa (20 to 145 psi), proof pressure is 1.5 MPa (215 psi), and the working temperature range is -5 to +70 C with no freezing.

How to choose
Pick this code when you want a 3/8 in port, a metal bowl and automatic draining, but you will mount the unit on rigid piping rather than a panel: the J option deletes the bracket that comes with the sibling GPF400C10AM. If your line is 1/2 in instead of 3/8 in, move to the GPF400C15AJM port variant. For finer 0.01 um filtration be aware the D-element versions pass less flow, so the 1100 L/min of this M-element unit is the better match when air demand is high.
Applications
Protecting control valves
Install upstream of pneumatic valves and actuators so the 0.3 um element removes oil mist at 99.9% efficiency before it reaches sensitive sealing surfaces.
Machine tool air supply
The automatic drain keeps condensate out of the 89 cc metal bowl on machines that run unattended shifts between maintenance visits.
Rigid manifold piping
With no bracket supplied, the unit suits installations where the 3/8 in PT connections on a fixed steel or copper air line carry the body securely.
FAQ
What are the key figures of the GPF400C10AJM?
Port: 3/8 in, PT thread. Element: 0.3 um (M) at 99.9% efficiency. Rated flow: 1100 L/min (inlet 0.7 MPa, outlet 0.5 MPa). Operating pressure: 0.15 to 1.0 MPa (20 to 145 psi), proof pressure 1.5 MPa (215 psi). Temperature: -5 to +70 C, no freezing. Metal bowl capacity: 89 cc. Drain: automatic. Weight: 620 g. Configuration: no bracket (J).
What does the J at the end of GPF400C10AJM change in practice?
In the GPF ordering code a blank position means a mounting bracket is included, while J deletes it. So this code is the piped-mounting version of the same metal-bowl, automatic-drain, 0.3 um unit; order GPF400C10AM instead if you want the bracket in the box.
