Why use a Compressed Air and Vacuum System? Many find it difficult to decide whether to use stand-alone pumps or complete tank packages for their applications. The tank system offers many advantages, which satisfy: High Volumes Quiet Operation If your application requires an instantaneous supply of high pressure or vacuum, then the reservoir provided by a tank system is essential. Even the largest of pumps has to start at atmospheric pressure and therefore will not be able to give that instantaneous supply of pressure/vacuum. In a tank system the pump runs on demand, which means that it is not...

Technical Data Compressed Air Systems Moisture When air is compressed in a tank system, water accumulates in the tank. To understand how this works, think of a stack of sponges saturated with water. Exert pressure on the sponges and water comes out. Compressing volumes of air has the same effect. The humidity in the air accumulates in the tank, which will require draining. If you are considering a tank system for an application that requires moisture-free air, the design should include a refrigerated, or desiccant type air dryer. Consult your Gast Distributor for more information. Air Consumption/Air...

Technical Data Vacuum Forming Work sheet Sizing a Vacuum Receiver To understand tank sizing for a desired level of vacuum, it is important to remember that the volume of the tank vs. the volume of the mold will determine your system vacuum. Example: Let’s assume that for each inch of mercury we have one “super molecule”, and we have a tank that is 1 cubic foot and a mold that is 1 cubic foot. At sea level the barometric pressure is 29.92 inHg absolute (0 gauge). Due to variations in the atmospheric pressure, we can safely assume that 30 inHg is a good round number. So, at sea level we can say...
