1 Blower Business Group TURBO BLOWERS 4-44 OSI ,000 CFM Bulletin 2300 June 1998 FEATURES Widest range of sizes available in the turbo blower market to meet the needs of the combustion, drying, and process industries. Energy efficient 60 hertz motors on all blowers 5 hp and above that meet or exceed the 1992 Energy Act which became effective in High volume blowers are available in 1800 rpm or 3600 rpm with single or multiple stage designs to meet the needs of the most demanding situations. Horsepower and impeller selection designed to achieve flat performance curves to minimize variations over the operating range of the blower. Blower shown with optional 2923 Filter Full array of accessories include 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 capabilities are shown on the succeeding pages of this bulletin. While motors with 1.15 service factors are more and more available, it is wise to allow some capacity safety margin when picking a blower for a calculated cfm requirements--unanticipated piping leaks, variations in burner capacity, and other unforeseen 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). Typical 2300 Blower Installation Altitude and preheated air effect blower ratings--pressure, capacity, and horsepower. For blower selection/performance at altitudes significantly above sea level, the blower section of the North American Combustion Handbook is recommended. Generally, standard motors can be used up to 3300 feet elevation; special construction is recommended above 3300 feet. See Bulletin 2600 if Blower will handle air hotter than 250 F. CONSTRUCTION All metal construction including mild steel, cast aluminum, or corrosion resistant stainless steel create a nearly indestructible blower allowing for years of trouble free service. Specially fabricated aluminum or steel impeller designs reduce vibration, lengthen motor life, and lower energy consumption due to lightweight construction technology. Individual impeller dynamics assured by either single or two plane balancing to minimize vibration and assure longer bearing life. Strategically positioned bolt hole locations allow for in-field repositioning of air flow discharge. Standard shaft motors on most single stage blowers reduce replacement downtime in the field. Standard inlet includes a guard. Threaded or SW unthreaded adapters can be specified in place of the guard for mounting optional filters or silencers, or if a 2947 blower sleeve will be used to accommodate inlet piping. Blowers with 8" or larger discharge are supplied with SW unthreaded adapter suitable for a flexible sleeve or welding. Blowers with 6" or smaller discharge normally have a threaded (fpt) flange, but the SW unthreaded discharge can be specified at no extra cost.

Printed in USA NA1100-Dims2300-D "SW" means sleeve or weld. A flexible rubberized sleeve (Bulletin 2947) can be slipped over an SW connection and clamped to prevent leaks. A flexible connection does not transmit vibrations or stresses as do welded or threaded connections. Fig. 1. Fig. 2. Fig. 3. Discharge Connections: A threaded (female) flange (Fig. 1) is furnished as standard with blowers of 6" and smaller discharge pipe size. An SW connection (Fig. 2) is standard for 8" and larger, or may be specified (at no extra cost) for smaller sizes (Fig. 3). Inlet Connections: A heavy wire guard (Fig. 1) is standard. An SW inlet (unthreaded, Fig. 2) for sleeve or welding connection may be specified at extra cost. A threaded female inlet may be specified for 3" through 6" inlet at no extra cost (Fig. 3).
