NEUDORFER <br /> ENGINEERS <br /> AN integm COMPANY <br /> Test and Balance <br /> Executive Summary <br /> This project has been balanced per plans and specifications using the National Environmental Balancing <br /> Bureau (NEBB) standards and procedures, and in accordance with the approved Test and Balance <br /> Strategy. All systems that did not achieve specified balancing tolerances or that were found to have <br /> performance and or installation deficiencies, are recapped below in the executive summary. <br /> All air systems have been inspected and measured for fan operating data, operating amperage, voltage, <br /> rotation, RPM, belt tension, alignment, and operating static pressure. All Grilles, Registers, and Diffusers <br /> (GRDs) have been proportioned to +/- 10 % of the percentage of design airflow of the system unless <br /> specified otherwise. <br /> The Test and Balance Balancing Tolerances for Air Systems specified for this project are as follows: <br /> • Supply, Return, and Exhaust Fans and Equipment with Fans: Plus or minus 10%. <br /> • Air Outlets and Inlets: Plus or minus 10%. <br /> Scope of Work <br /> The scope of work for this project includes the Air Test and Balance of 2) Fan Units. <br /> Air Systems Summary <br /> Supply and Exhaust Fans <br /> Fans were checked for proper operation, rotation, amps, and volts. Fans are balanced to meet design <br /> flows. All grilles and exhaust inlets are balanced to meet specified flows. <br /> EF-1 <br /> Total airflow was determined by duct traverse at the exhaust stack. The bypass airflow was determined <br /> Page 4 of 16 <br /> Hyperlink to Table of Contents <br />
