Explanation of designation: 2304-11/1- _ .3D means Series 2300, 4 osi pressure, inner housing no. 11, 1 stage, 1⁄3 hp motor, direct drive. d With drip-proof motor, if dimensions are different from TEFC. t With TEFC motor, if dimensions are different from drip-proof. * Z = Motor overhang for TEFC motors. There is no overhang for drip-proof motors, except 2320-33/1- _ 40D and 2324-33/1- _ 40D which overhang ½ ". ‡ Listed T and U dimensions are for SW inlet. For threaded inlet where S = 3", T = 1 ¾ "; S = 4", T = 1 7⁄8 "; S = 6", T =5". If S is greater than 6", threaded inlet is not available. † SW discharge (unthreaded pipe) is included in F. Discharge C is 10 9⁄16 " from farthest base hole, for inner housing no. 11. § Female pipe thread. If SW discharge (unthreaded pipe) is specified, add 3 ¼ " to F. 5 holes when No. 4 discharge is furnished. When #4 discharge position is specified, all blowers except those in discharge position group A, B, or C, require a modification of blower base (reference Bulletin 2300). L
Inlet or outlet adapters are not included as standard supply and must be specified at an additional cost.
" SW " means sleeve or weld. A flexible rubberized sleeve (Bulletin 2947) can be slipped over an SW connection and clamped to prevent leaks. A flex- ible connection dœs not transmit vibrations or stresses as do welded or threaded connections. Blowers are not designed for imposed loads from hard pipe connections and should not be "hard" piped except under unusual circumstances.

Discharge Connections: A threaded (female) flange (Fig. 1) is available with blowers of 6" and smaller discharge pipe size. An SW connection (Fig. 2) is available for 8" and larger, or may be specified for smaller sizes (Fig. 3).
Inlet Connections: An SW inlet (unthreaded, Fig. 2) for sleeve or welding connection is availabe. A threaded female inlet (Fig. 3) may be specified for 3" through 6" inlets. For an open inlet, an inlet guard should be specified (Fig. 1). Blowers should not be operated without inlet protection.
