Application of Air Amplifier

As the name suggests, the traditional use of an air amplifier is when a process calls for a higher pressure than what is provided by the plant's air supply. These uses, however, are not limited to compressed air since the "Amplifying" effect can be used with any inert gas as long as it is the same kind of gas that the operation needs but at a higher pressure.

This amplification procedure, also known as "Bootstrapping," varies from gas boosting in that it uses a different gas than that utilized in the higher pressure method to power the booster.

In essence, air-driven air amplifiers are air-driven gas boosters with a single, set-up requirement: identical driving and process gases. The mechanical distinction in air-driven gas boosters can be seen in the usage of mechanical and sealed separation (sealing) between the drive gas and the gas to be boosted. This sealed separation, which is a must for all gas boosters, ensures that the process gas won't be contaminated by the drive gas. For obvious reasons, there is no such requirement with air amplifiers.

Even though it can supply massive amounts of air, the plant's (reticulated) compressed air supply typically fails to sustain much more than 75–80 PSIG (520–550 kPag) (5–5.5 barg). Protech air-driven air amplifiers can be used in a variety of circumstances where different processes call for a supply of compressed air at higher pressures than the plant air system can deliver.

The most typical requirement is a straightforward 2:1 ratio amplification, which can, for instance, increase a plant air pressure system of 70 PSIG to 140 psi. Air-driven air amplifiers from Protech are available in a range of ratios up to 15:1. Plant air must be amplified with caution. Gas compression called amplification results in a buildup of heat. Large amounts of moisture in hot plant air can condense as it cools. The problem becomes more severe as the compression ratio increases. Make contact with Protech Pumps if you need help with this.
