Stairwell Pressurization Fans in Condominiums or Air Balancing of SCS (Smoke Control Systems) in Relation to Safety Systems

Enviro Balance conducts pressure differential testing between stairwell and floor corridors in different scenarios in relation to the doors being opened or closed in order to:

  • assure that any differential pressure measured is at least 0.1” w.g. and adjust it if necessary.
  • Assure any door pull force does not exceed 30lb and adjust it if necessary.

 Once deficiencies are corrected, we will retest and submit a report.
