Fan Systems

Optiline HE Fan Systems

Optiline HE fans feature a fully welded aluminum airfoil blade design for efficient and quiet operation, available in a single or multiple fan configuration. Multiple fan configurations are frequently the best choice as they offer many valuable system benefits, including:

  • Optimum Energy Efficiency
  • System Redundancy & Reduced Service Downtime
  • Improved Acoustical Performance
  • Reduced Unit Footprint

Spring Isolators

Spring isolators with seismic restraints are mounted on all Optiline HE Fan Systems, capable of satisfying OSHPD and IBC requirements (others can be reviewed).

Fan Wheel

All Optiline HE Fans include a fully welded fan wheel, that is designed, built, and paired with a motor to match the project ambient and airflow requirements.

Flow Trac™

The Energy Labs, a Vertiv™ Company Flow Trac system measures air flow rate. Using the fan inlet cone as a calibrated nozzle assures the airflow and sound levels are not affected by obstructions in the flow path.

IAQ Options

Modern buildings require ventilation rates to comply with ASHRAE Standard 621 as well as Good Indoor Air Quality (IAQ). Poor IAQ has been directly associated with “sick-building syndrome”, which can result in high illness rates, absenteeism, reduced productivity, and employee turnover.

IAQ Condensate Drain Pans
  • Double-sloped design to prevent standing water
  • Pans completely cover the coil plenum section width
  • Pans are insulated with spray foam
  • Fully tig welded construction
  • Stainless steel drain connections and piping
  • Available in threaded NPT connections
