Maintain space temperature with primary flow control and intermittent fan operation for energy reclamation from warmer ceiling plenum during heating cycles.
Control strategies using pneumatic, analog, or direct digital control (DDC) systems
Product Features
Efficient, 3 Speed motor (permanent split capacitor) with thermal overload protection allows horsepower change for greatest potential of energy savings. 120 or 277 vac, 1ø
Solid state speed controller with factory calibrated minimum voltage setting for precision air flow adjustment.
18 & 20 gauge zinc-coated steel design for rigidity.
1" dual density thermal / acoustic internal insulation (NFPA 90A & UL 181)
Easy to install and service – all controls located in one convenient location for single point electrical connection.
Swing-down fan access panel
Steel control enclosure, screw attached cover. Left hand position is standard.
90º inlet damper & perimeter seal limiting leakage to <1% of max rated flow at 3" w.g. inlet static pressure.
Patented Velocity Wing primary flow sensor measures flow to ±5% accuracy regardless of inlet conditions. Highest velocity pressure amplification means high turn down with high accuracy.
Internal Insulation - 1/2" or 1" foil-faced glass fiber insulation with metal taped edges meeting ASTM C665, double wall construction, Lo-Temp casing construction, 3/8" fiber free closed cell foam insulation, no insulation, see page A-11.
Slip & drive cleat discharge collar
1" Throw-away filter & filter rack
Unit mounting brackets (field installed)
Electrical component options – line voltage disconnect switch, power fusing, 3-speed manual motor selector switch, electric damper actuator (24vac) for use with DDC controls, fan relay for on-off function, 24vac step down transformer
Digital, analog, or pneumatic control systems
