Gas pressure booster 7A-DS-8

air

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. INSTALLATION AND CONTROLS Although there are a number of options for controlling these units, a final recommendation will be based on how the high pressure output air is to be used. Perhaps the most common type of control is that similar to a conventional air compressor: 1. Amplify the air into a receiver tank, ASME coded if permanently mounted. 2. Provide a safety relief valve at maximum rated tank pressure. 3. Provide a pressure switch* set to stop the air amplifier unit at about 95% of safety relief valve setting. 4. Provide an air or gas regulator (reducing valve) on the tank output set at the minimum usable amplified air pressure for the application. * The pressure switch need not be electrical. Instead, the HII series of PCV valves performs this function in one simple unit with no electrical input required.
