This product has been discontinued.

This unit has been replaced by a new model, the Tri-RAM 728. Please note the TRI-RAM has integral DIN flanges and therefore is NOT a drop-in replacement. If you need to replace a RAM X unit in an EasyAir package, the silencers and other components may also need to be replaced.

If you have an existing model that needs service or repair, some parts are still available. Contact us to schedule service.
