The F90A Self-Contained Electronic Commercial Air Cleaner is ceiling-mounted and removes airborne contaminants such as tobacco and cooking smoke, dust, and pollen from the air circulated through the unit. Surface mounts in a 2x2' ceiling tile or half of a 2x4' ceiling tile.
The F90 provides Coanda air distribution by drawing in dirty air from below, cleaning it electronically, and discharging the clean air in four directions parallel with the ceiling.
F90A capacity is 1250 cubic feet per minute (cfm at HI speed).
ASHRAE recommends a minimum air circulation of 30 cfm per person for bars and cocktail lounges. Thus each F90A can handle a room with up to 41 people. Clean outdoor air is also required to replenish oxygen and dilute gaseous contaminants.
