Fans : 3300 Calibrated Fans
Retrotec 3300-Series fans are designed for testing any residential house or enclosure from 12 ft2 (0.8 m2) of leakage 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. Eight point fan mount makes this calibrated fan the strongest made.
Variable Frequency Drive has a built in computer that:
- Allows the DM-2A to control the fan.
- Regulates the speed within a few RPM.
The variable frequency drive will operate using anything from 100 to 240 Volts AC, 50 to 60 Hz with no loss of power.
