Type of Comment: Technical (substantive)

Comment (justification):
revision of my earlier proposal clearly separate 230 products from 250 products

Proposed Change:
AMCA 230 should say that circulation fans are used without ducts for recirculating air in a space primarily for temperature- or humidity-destratification of room air, or for comfort-cooling based on evaporation.
