Air curtains, with their ability to both sanitize interior
spaces (in combination with a UV package) and keep out
exterior pollutants, are capable of contributing to IAQ in
ways other auxiliary HVAC equipment is not.

International's Certifi ed Ratings Program (CRP)
is a globally recognized third-party program
assuring not only that a product line was tested
and rated in accordance with AMCA standards
and requirements but that the published performance
ratings are accurate and, thus, reliable.
To ensure a specifi cation clearly requires an
AMCA-certifi ed air curtain, include statements
similar to:
All air curtains shall bear the AMCA Certifi ed
Ratings Program seal for Air Performance.
All air-curtain units shall bear the AMCA Certifi
ed Ratings Program seal for Sound and Air
Performance.
The following language should be avoided in
specifi cations:
■
" Tested in accordance with " : A product that
was tested in accordance with an AMCA
standard is not necessarily an AMCA-certifi
ed product.
" Tested in an AMCA or AMCA-accredited
laboratory " : Again, this language provides
no assurance a product is certifi ed.
To learn more, read the white papers " Introduction
to the AMCA Certifi ed Ratings Program, "
" How to Ensure AMCA-Certified Products
Get Installed, " and " Guideline Specifications
for AMCA-Certified Products, " available
