The Roots EasyAir or EAX line of OEM blower packages often include a tri-lobe blower. Originally this was the RAM-X series of blowers, until 2016 when these were replaced by the TRI-RAM blower series.
The RAMX blowers featured rectangular connections that had optional bolt-on flange adapters. When the TRI-RAM series was introduced in 2016, these units also had the same rectangular connections, however in 2021 Roots redesigned the TRI-RAM blowers to have integral DIN flanges.



If your EasyAir package contains a blower (RAM-X or TRI-RAM) with rectangular flanges and bolt-on flange adapters, and you are switching to a current TRI-RAM with integral DIN flanges, unfortunately you will also have to replace some of the other components inside your EasyAir package.
