Integrated thermal break frame (ITF) and welded frame (WF-2) air handlers by Nortek Air Solutions (NAS) have received top hurricane ratings from the Miami-Dade County, Florida, and its High Velocity Hurricane Zone building codes.
The ITF and WF-2 commercial and industrial air handling models achieved notice of acceptance (NOA), passing the nation’s most stringent unit wall pressure tests, and now boasts the highest mile per hour (mph) wind load rating in the HVAC industry. The claim is proven by the first, second and third ranking it received above all other Miami-Dade County-Certified air handler brands.
