North American Series 2300 Turbo Blowers 4-44 OSI & 55-11,500 CFM for standardized product 4-60 OSI, up to 100,000 CFM for custom product FEATURES — Direct drive blowers specifically for combustion applications, which are also an excellent choice for uses such as pressurized air supply, drying, conveying and other application in process industries. — Available in singe or multiple stage designs at 1800 rpm or 3600 rpm; the Series 2300 blowers are capable of performances not achieved by any other comparable blower design. — Horsepower and impeller selection designed to achieve "flat" pressure performance curves to minimize variations over the operating range of the blower. — All 60 Hz blowers are equipped with Premium Energy Efficient Motors which meet the requirements of EISA (except units with fractional 56 frame and see Series 230050 cycle for 50 Hz motor standards). — Full array of accessories includes filters, silencers, filter/ silencers, inlet and outlet adapters, flexible sleeves, inlet vane dampers, AC frequency drives, combination motor starters and fusible disconnects. These options offer the protection needed to keep operational costs down while increasing blower life expectancy. SELECTION Pressures and volume flow at air density of 0.075* pounds per cubic foot are shown on the following pages of this bulletin. It is wise to allow some capacity safety margin when choosing a blower based on the calculated cfm requirements-unanticipated piping leaks, variation in burner capacity, changing process back pressure and other unforseen factors could cause motor overload unless there is some cushion. Without prior knowledge of leakage and other conditions, a 10% safety margin is considered minimum. It is also important to allow for pressure losses in piping, fittings and valves which reduce pressure available at the burner (or other end use). *Air density @ 1 ATM @ 70° F. fan industry standard temperature Blower shown with optional 2923 filter For volume flows greater than shown in the bulletin consult North American for custom selections designed to the exact requirements of the application-see "2300 Custom" section of this bulletin. Altitude, air temperature and composition affect blower ratingspressure, capacity and horsepower. For blower selection/ performance at elevated temperature or altitude significanlty above sea level, the blower section of the North American Combustion Handbook is recommended as a guide to select the proper blower/motor combination. Generally standard motors can be used up to 3300 feet above sea level; special construction is recommended above 3300 feet. Do not use Series 2300 blowers above 200 degrees F. See Bulletin 2600 for applications that require operational temperatures greater than 200 de

CONSTRUCTION Series 2300 blowers are available in coupled drive (AMCA Arrangement 8), and belt drive (AMCA Arrangement 9), but most users select the standard direct drive design where the impeller is mounted on the motor shaft (AMCA Arrangement 4) for simplicity with minimal maintenance. All metal construction including mild steel, cast aluminum, or corrosion resistant stainless steel creates a nearly indestructible blower allowing for years of trouble-free service. Fabricated aluminum or steel impeller designs based on lightweight *rospace technology provide significant benefits; high...

2300 SERIES CUSTOM BLOWERS For performance requirements greater than those of the standard 2300 Series Blowers (to flows of 100,000 ACFM and pressures to 60 OSI), custom designed units are recommended. When flows and pressures become larger, designing a unit specifically for the duty (plus any required margin) saves both initial cost and energy. FEATURES — Designed specifically for the application requirements, the 2300 Series Custom blower uses the most appropriate/ highest efficiency impeller design including radial blade, backward curved, and airfoil. Our designs include special low...
