3300 Series Calibrated Fans
Capable of up to 8100 CFM with a 2hp motor, Retrotec 3300-Series fans are designed for testing any residential house or enclosure from 12 ft2 (0.8 m2) of ELA (estimated leakage area) down to tight houses and small enclosures with 15 in2 (97 cm2).
The 3300-Series Fan uses a precision pieziometric ring on the inlet motor nacelle to ensure accurate flow readings. A solid, eight-point fan mount makes this calibrated fan the strongest model in production.
