Design-Aire SL-EC The Design-Aire SL-EC is the model for the energy conscious user. These fan-filter units feature Electronically Commutated motors that use less energy and create less heat when they are set to run at lower speeds, in contrast to the AC motors that run at maximum energy output regardless of the speed setting. The energy savings these units afford make up for the additional cost within 2 years of typical operation. The Electronically Commutated motors also allow these units to be used in facilities where computerized building controls exist. Standard Features Optional Features Easy Installation The 11.5” height and light-weight housing of these units make them easier to slide into ceilings. The 3prong electrical cord allows them to be plugged into standard 115V outlets. High Efficiency Particulate Air (HEPA) filter rated 99.99% efficient at 0.3 microns HEPA Duration The variable speed control helps increase HEPA filter life by allowing the motor speed to be increased as the loading on the filter increases. This keeps the airflow consistent and results in fewer filter changes. Disposable, quick-change pre-filters, rated MERV 7 2" pleated pre-filter in place of standard 1" Less then 64dba noise levels Minihelic Gauge, to monitor loading on filter Energy Efficient Each unit only uses a maximum of 1.0 amps. Convenient Connections A 115V duplex electrical outlet located in the filter housing allows up to 10 units to be connected to and run from one 15-amp circuit. Uniform airflow across filter face Durable, light-weight aluminum housing Painted Aluminum or Stainless Steel housing Ultra Low Penetration Air (ULPA) filter rated 99.9995% efficient at 0.12 microns HVAC collar connections Duplex electrical outlet, 15A, 115V Sound Insulation Package 15' power cord, 115V – no hard wiring required!
