The RO-98634 seen here in action. This 24V, low profile unit is a revised version of a previous model, featuring low profile housing - fantastic for trucks or heavy equipment cabs like the crane seen here. 

The low profile plenum protrudes barely 1.5" into the cab and blends easily into the headliner leaving ample head room. Frigid, high-velocity air can be directed 360° through the large diffusers located directly below the double blowers. Also featured is a cab air filter incorporated into the plenum.

Testing during the development of this unit showed a 28% weight reduction and 30% performance increase, in comparison to the pre-existing design.
