Facility Testing, Adjusting, Balancing (TAB) for Air Systems

Pro-MEC Engineering Services, Inc. (Pro-MEC) is a firm certified by the National Environmental Balancing Bureau in Air Systems Testing, Adjusting and Balancing (TAB) of commercial and institutional facilities. This covers work of the following nature:

  • New construction air systems TAB
  • Renovation/alteration air systems TAB
  • Pre-design air TAB for alteration/renovation feasibility studies
  • Troubleshooting and performance studies of existing systems

In conducting air TAB projects, Pro-MEC includes the following as part of the final report:

  • Title/cover page with all applicable project and contact information for design team and contractors
  • Table of contents as a summary of all TAB reports included therein
  • Equipment list summarizing all testing equipment used and dates of calibration for each
  • System diagram showing all terminals attached to the associated air moving equipment
  • Air moving equipment apparatus reports – each including original design values vs. manufacturer’s submittal data vs. actual data observed (fan nameplate information, motor nameplate information, static pressure profiles, motor overload protection information, motor starter information, brake horsepower calculation, airflow at fan vs. airflow at terminal(s))
  • Terminal airflow reports for constant volume, variable volume, multi-zone constant volume, fan-powered variable volume, etc. Each contains a heading for outlet location, outlet number, size of terminal neck, K factor, design airflow – maximum/minimum if applicable, actual airflow – maximum/minimum if applicable and per cent of design for each as well as for the system as a whole
  • Velocity traverse and profiles report highlighting the location of each traverse taken along with the dimensions of each test point in a rectangular or spiral duct (each report lists location, duct size, free area, design airflow, design velocity, actual velocity, actual airflow, per cent of design and centerline static pressure at the pitot traverse location
