COBB COUNTY FIRE DEPARTMENT
Model DF0973 Medium-Duty Rescue
Cobb County is now operating its second Hackney Air/Light vehicle serving the busy north Atlanta metro area. The 18-ft body has nine roll-up door compartments. The four compartments forward of the rear wheels are 40" deep floor to ceiling courtesy of the drop/pinch frame. It is mounted on an International 4400 with 330 hp engine.
The breathing air system is a Scott 26 cfm using a cast-iron Ingersoll block that operates at a cool and quiet 1000 rpm's. The fill station is a RevolveAir that permits two SCBA bottles to filled while two more are being staged, increasing filling capacity per/hour by 30% over conventional systems.
The right front compartment has tubes for storage of thirty (30) one-hour SCBA bottles and twelve (12) "E" cylinders of medical oxygen. A tunnel compartment in the top of the second compartment carries not less than twenty (20) long backboards. The backboards and oxygen are for MCI deployments.
A 40,000 watt, 3-phase Onan PTO generator provides power to the compressor, the NightScan light tower and two portable tripod flood lights.
All lighting is LED with a V-MUX multiplexed electrical system and color Vista LCD control panel.
