This detailed engineering drawing depicts a 15HP industrial centrifugal blower designed for handling chlorine gas (CL2). This assembly features a fiber-reinforced vinyl ester (FRVE) casing with 6mm thick walls and an Ø875mm diameter impeller. The blower operates at 2100 RPM, delivering 2000 NCMH airflow at 500mm WC static pressure. Key components include an EN-8 shaft (Ø55mm) with FRVE sleeve, SN 612 pedestal with SKF 2312K bearings, and a 15HP/1440 RPM IE2/NFLP motor. The drive system utilizes a pulley arrangement (236×3B driver, 160×3B driven) with belt guard. The assembly includes flanged connections conforming to DIN ASA-150-B-16.5 standards, anti-vibration mounting pads, and an MS base frame with ISMC 100×50 and ISA 50×50 structural members. The unit weighs 475kg with motor (325kg without) and can handle operating temperatures up to 50°C with static and dynamic, in essence, loads of 750kg and 1350kg respectively. The drawing includes multiple views (top, side, suction end) with detailed flange specifications and comprehensive bill of materials.
