Description

  • The Flexmaster NovaVent 2NVTB4 Termination Box 4" 440 SS is an industrial-grade, commercial-grade equipment component engineered specifically to ensure absolute airtight fire-safe flue extraction and secure building exterior termination across demanding high-efficiency condensing gas systems.
  • Fabricated from premium 440 superferritic stainless steel alloy panels, this high-performance component handles severe positive pressure Category II, III, and IV flue gas profiles with robust mechanical permanence while permanently resisting aggressive chloride corrosion, acidic condensate pitting, and intense outdoor weather distortion.
  • The innovative flush-mounting single-wall termination layout significantly improves terminal air protection parameters to smoothly handle high-velocity draft fans and intense backdraft winds without causing system exhaust restrictions, localized wall discoloration, or high-limit pressure switch sensor trips.
  • Ideal for licensed HVAC/R technicians, mechanical contractors, and facility maintenance supervisors, this durable vent box features an integrated 4-inch connection collar to rapidly execute clean, direct field installations, maximize overall energy efficiency, and permanently eliminate expensive combustion safety callbacks.
