Air Compressors & Accessories  Selection and Design Proud Member of Dry Pipe System Air Compressors NFPA 13D Residential Fire Pumps
Presenter:  Geoff Pridham Technical Support Manager Background: ,[object Object],[object Object],[object Object],[object Object]
What we will cover today… ,[object Object],[object Object],[object Object],[object Object],[object Object]
Key Terms, Concepts & Codes NFPA 13 7.2.6* - Air Pressure and Supply - This section of NFPA 13 governs most of what we will be discussing today.
Key Terms, Concepts & Codes Holding Pressure - The MINIMUM pressure at which the system needs to be maintained (13, 7.2.6.6.1)
Key Terms, Concepts & Codes ,[object Object],[object Object],[object Object],[object Object],[object Object]
Key Terms, Concepts & Codes Holding Pressure  (System)   vs.   Feed Pressure   (from Compressor) - Feed pressure from the air compressor must be higher than the system holding pressure in order for the compressor to flow air into the system.
Key Terms, Concepts & Codes Pressure Drop and the Compressor ,[object Object],[object Object]
Key Terms, Concepts & Codes Pump Up Time - The pump up time is the time for the system piping to rise to the final design holding pressure.
Key Terms, Concepts & Codes ,[object Object],[object Object],[object Object],[object Object]
Key Terms, Concepts & Codes ,[object Object],[object Object],[object Object],[object Object]
Key Terms, Concepts & Codes Pressure Regulation - Pressure regulation is the varying (fine tuning) of the feed pressure from the compressor to the system. - Employ an Air Maintenance Device (AMD) (13, 7.2.6.5.1)
Key Terms, Concepts & Codes System Capacity - The total system capacity as far as compressor sizing is concerned should include the piping network as well as the compressor feed piping and riser volume  (13, 7.2.3.1)
Selecting A Compressor  by Type and Application Oil less… Lubricated… Parking Garage…   Freezer Room…
Selecting a Compressor by Type and Application ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Selecting a Compressor by Type and Application Oil less Air Compressors vs. Lubricated Air Compressors - Oil less  Pro:  Minimal Maintenance, Flexibility of Installation, Minimum Footprint Con:  Higher Initial Cost - Lubricated Pro:  Lower Initial Cost, Simple Parts Replacements Con:  More Frequent Maintenance
Selecting a Compressor by Type and Application Riser Mounted, Floor Mounted, or Tank Mounted? High Pressure, Standard Pressure, or Low Pressure? - Dictated by valve selection and holding pressure
Selecting a Compressor by Type and Application ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Selecting a Compressor by Type and Application ,[object Object],[object Object],[object Object],[object Object]
Selecting a Compressor by Type and Application What ever you do ,   DO NOT USE A RETAIL AIR COMPRESSOR IN A DRY PIPE SYSTEM ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Selecting a Compressor by Type and Application Important Note on Voltage: ,[object Object],[object Object],[object Object],[object Object]
Air Compressor  Accessories Motor Starters… Pressure Switches… Air Maintenance Devices…
Air Compressor Accessories Motor Starters (Line Starters): General Air Products' IEC Line Starter  provide protection to motor windings from harmful currents that result in temperature rises that may be caused by either overloading the motor, sustained low line voltage, or locked rotor. Note:  We strongly recommend that a line starter accompany every General Air Products' air compressor.
Air Compressor Accessories Pressure Switches: ,[object Object],[object Object]
Air Compressor Accessories Pressure Switch and Line Starter Wiring Diagram:
Air Compressor Accessories Air Maintenance Devices: The  AMD-2  is used for automatic operation  with a dedicated air  compressor for a  sprinkler system,  such as a  base mounted  compressor. The  AMD-1  is used when compressed air is supplied through an existing factory air supply or when a using tank mounted unit.
