Aro-Flo Series Air Line Filter, 1/2 NPT Ports, 5 micron Element, 197 SCFM Flow Rating, 1.9 oz Bowl Capacity, Manual Drain

It uses 1/2 NPT ports, so it matches standard 1/2 NPT air line connections.

At 197 SCFM, it's got a little headroom above your 180 SCFM demand, so you shouldn't see any restriction under normal operating conditions. The 1/2 NPT ports match standard line sizing for that flow range, and the 5 micron element handles solid and liquid contaminant removal without significantly impeding throughput at rated capacity.

this Aro-Flo air line filter comes with 1/2 NPT ports, so you should be good to go.
