Fan Filter Unit
The Smart® WhisperFlow® has an electronically commutated (EC) brushless motor that allows for quiet, energy-
efficient operation and infinitely variable speed control. The wide range is ideal for applications involving high
static pressure. This unit includes an internal microprocessor that can be incorporated into Building Management
Systems (BMS) to allow remote monitoring and control. The EC motor offers high performance, low energy
consumption and low noise levels (40 dB) with forward-curved centrifugal fans. These units comply with Title 24
and ErP 2015 Directive. There are permanently-lubricated bearings for long service life and a forward-curved
blower wheel that is factory balanced. The FFU uses FDA-approved Acrylic Urethane sealant and fire retardant
phosphorus free polyurethane sealant.
