Specifications include, but are not limited to: Curb side, in shock-mounted panel. Electronic Throttle with Digital Read Out. Keyed On/Start/Off Switch. Digital Voltmeter - Tachometer - Hour Meter - Water temperature and Oil pressure with safety shut-off. Emergency Stop Button; A. The 25” diameter suction fan is direct driven by heavy duty push-button electric/hydraulic-engaged clutch through a 2 1/4" diameter straight output shaft. ; After welding, the complete fan is stress relieved for two hours at 1100 degrees F using an atmosphere controlled gas fired heat treatment process. This treatment relieves stresses induced by welding and reduces the possibility of weld failure due to shock loads. Non gas fired heat treatment or vibratory stress relieving processes are not acceptable as they produce brittle fans subject to cracking and early failure. ; The 12 volt electric-hydraulic power unit provides up and down movement of the standard hose boom. This is done through a two inch cylinder that is activated with push button switches mounted in a hand held pendant which can be mounted at the operator's station
