TAT QCA Ceiling Cassette Exhaust Fan
Concealed ceiling-mounted ducted exhaust fans with high-grade PP brown casing, flush white room-side grille, and 12 verified 60Hz operating configurations across six model sizes (50QCA to 300QCA) for residential and commercial clean-air ventilation in Saudi Arabia.
Engineering & Application Overview: TAT QCA Ceiling Cassette Fan
The TAT QCA ceiling cassette exhaust fan is a concealed, ceiling-mounted ventilating fan featuring a durable brown polypropylene (PP) casing, a flush architectural white room-side louver grille, and an integrated centrifugal blower wheel. Sized across six models from 50QCA to 300QCA, the series provides published catalogue air delivery ranging from 50 to 308 CFM. Compact models (50, 80, and 120QCA) utilize a 105 mm spigot for nominal 4-inch ductwork, while larger models (160, 240, and 300QCA) utilize a 155 mm spigot for nominal 6-inch ductwork. The range supports both 127V 60Hz and 240V 50/60Hz electrical supplies in Saudi Arabia. Because catalogue airflow is published without an explicit static pressure basis, duct resistance must be calculated to confirm delivered CFM, and exhaust air must always be ducted directly to exterior louvers or building ventilation risers.
TAT QCA model range (12 verified 60Hz configurations)
Extracted from the primary reference schedule (Arabian Co. for Fans). 127V 60Hz and 240V 50/60Hz options are explicitly separated to prevent hybrid errors. Values represent catalogue air delivery; test and static-pressure basis is not stated in source literature.

Catalogue CFM ratings are published without an explicit static pressure operating point. When connected to flexible ducting, bends, backdraft dampers, and external louvers, delivered airflow will decrease. Application profiles are preliminary recommendations; final engineering selection should calculate design CFM from room volume and air changes per hour (ACH) intersected with system duct resistance.
