The Kussmaul AC Auto Pump Timer is an automatic duty-cycle controller designed specifically to help protect compatible 120 VAC Kussmaul Auto Pump air compressors from overheating and excessive wear caused by continuous operation. Designed for fire apparatus, rescue vehicles, and other emergency or specialty vehicles, the timer helps extend compressor service life when excessive air system leakage causes the Auto Pump to operate continuously.
The timer automatically limits compressor operation to one hour of continuous running followed by a one-hour OFF period for cooling. This controlled duty cycle helps reduce operating temperatures, minimize excessive compressor wear, and maintain pump efficiency. The AC Auto Pump Timer operates automatically without interfering with normal compressor operation and is designed for straightforward installation with compatible Kussmaul Auto Pump models.
