DOWNBLAST CENTRIFUGAL ROOF EXHAUSTER WITH ELECTRONICALLY COMMUTATED MOTOR
Constant Pressure Control Options with eRED
Constant Pressure Controls: For constant pressure control applications,
the S&P constant pressure control package is available. This package
includes the components that are needed to complete a demand-based
exhaust ventilation system for kitchens, bathrooms, and/or clothes dryer
exhaust in multi-story buildings.
S&P recognized that the programming procedure for many constant pressure
controls can be challenging, so this package is the simplest system available.
The control box can be easily installed in the eld, either mounted on a curb
or inside the building. The backlit LCD display and pressure transducer are
pre-programmed to work together to increase or reduce the speed of the
fan to accommodate for the actual demand.
Potentiometer Shipped Loose: If a variable rate that is manually changed
by the operator from the occupied space is desired, the potentiometer is
shipped loose and eld installed in the appropriate accessible location. Simply
rotating the dial will vary the speed of the fan from 20% to 100% full speed.
