The SVI Type 3 for Aspen has a Hale 1,000-gpm single-stage PTO-driven pump that has stationary pumping and pump-and-roll modes, a 750-gallon polypropylene water tank, a 20-gallon foam cell, and a FoamPro 2001 electronic foam system. The Aspen Type 3 has electrically actuated aluminum hosebed covers, a curbside Zico electric-over-hydraulic ladder rack, and an Akron Brass Apollo 1,500-gpm deck gun. An Elkhart Brass Sidewinder remote control monitor occupies the front bumper on the Aspen Type 3 WUI pumper. Aspen chose non-SCBA H.O. Bostrom air suspension seats for the interior of the Type 3 pumper and mounts its SCBA in the R1 curb-side compartment. The Zico ladder rack holds a 24-foot extension ladder, 14- and 10-foot roof ladders, two pike poles, and one 10-foot section of 5-inch hard suction.
