(Redirected from EFI System partition) The EFI system partition (ESP) is a partition on a data storage device (usually a hard disk drive or solid-state drive) that is used by computers adhering to the Unified Extensible Firmware Interface (UEFI).
As much as 80 to 90% of the electrical energy used by an air compressor is converted to heat. A properly designed heat recovery unit can recover 50 to 90% of this heat for heating air or water.
For example, a compressor may be capable of pumping 40 litres of air per minute at 0 psi and 30 litres of air per minute at 30psi. To get an idea of how compressors compare with each other in performance, have a look at the airflow claims and see which one comes out on top.
