S42N5D
2Pages

The boosted gas flowrate and discharge pressure can be controlled by throttling the drive air flowrate and/or regulating the drive air pressure. When there is no demand for high pressure gas, the system will stall when it reaches the maximum discharge pressure. When there is a need for high pressure gas the pressure in the discharge line drops, and causes the system to restart automatically. The S42N5D can be operated using a single booster or both boosters in unison. During single booster operation, the idle booster can be isolated and depressurized allowing it to be either removed from the system for maintenance, or placed in a stand-by mode when higher flowrates are not required. This redundancy feature eliminates costly process downtime. Drive Air Inlet DESCRIPTION Port The S42N5D dual gas pressure booster system uses shop air to boost the pressure of an air or gas stream. The drive air piston reciprocates automatically and drives the gas compressor piston. The boosters are unlubricated, and use filled Teflon® piston seals and rod seals. They requires no electricity, cooling water, air-line lubricator, and are explosionproof. 5/1 Dual Gas Pressure Booster System on a 5.5 Gallon Tank MPS M I D W E S T 1-1/2" Square 18.0 PRESSURE Aluminum Rail Lengths Quantity:S Cut Length: S SY T E M Dimensions are in inches 1 1 1 1 Gas Discharge !

S42N5D Discharge Pressure vs Flowrate! Shop drive air pressure and gas supply pressure are the same. 500 Discharge Pressure in psig bottom line to determine the maximum flowrate of 14.8 scfm. During single booster operation the maximum flowrate is approximately half of the flowrate found on the graph (7.4 scfm). The system can operate at any flowrate from zero to the maximum flowrate. The boosters will automatically adjust their operating speed as long as the required flowrate is in this range. Midwest Pressure Systems, Inc.! 1035 Entry Drive, Bensenville, IL 60106!
