Hydraulics International air driven air pressure amplifiers operate using the principle of differential areas. Like any air tool,they operate from a single shop air connection for most applications. The air used for cycling exhausts through the muffler provided, or may be piped out of the area. The rest of the air is compressed to a higher pressure output. When output demand stops, the unit will stall in a force balanced condition consuming no power nor generating any heat. When output demand resumes, the unit automatically responds and cycles at the rate needed to meet that demand, up to the units capacity. Output Flow Reaches Maximum as the amplifier’s output pressure approaches the plant air input pressure. Output Flow Drops to Zero as the unit reaches theoretical stall. This value is estimated by multiplying input pressure x the last digit of the model number, e.g. model 5A-DS-5 with 100 PSI (6.9 BAR) plant air input will stall at approximately 500 PSI, model 5A-DS-2 at approximately 200 PSI (13.8 BAR). In practice however, controlling the maximum pressure desired is usually done with an external control.
