Features	Functions	Benefits
Standard filtration for exhaust airstream	Filters out particulates	keeps energy recovery module clean less maintenance maintains high efficiency of energy recovery module
Medium efficiency filtration for supply airstream	Dust spot efficiency greater than 30% Keeps energy recovery module clean	clean air for proper IAQ levels and low maintenance for energy recovery modules
Easy to service	All regularly maintained components are accessible in 7 minutes or less.	save maintenance time and money
All motors feature inverter spike resistant wire/auto overload protection	Ideal for inverters/speed controls	100 times more resistant to transient spikes, high frequencies, and short rise time pulses produced by inverters
Standard high efficiency motors for 143T, 145T and 184 frames	High efficiency electrical motors	meets EPAC regulations and reduce operating costs
High pressure ventilators	Nominal airflows rated at minimal 1" ESP (external static pressure) capability	allows for long distribution lines and ability to add duct modules without sacrificing airflow
Optional internal heating and cooling available	Controls air quality, temperature and humidity	one complete package that takes care of all HVAC needs
ETL and cETL approval on all products	Products approved to UL Standard 1812 "Ducted Heat Recovery Ventilators" and CSA C22.2 No. 113 Fans of Ventilators	meets electrical safety requirements on site approvals not required
Meets ASHRAE 62-99 for ventilation requirements	Energy recovery 100% outdoor air ventilators with exhaust and supply blowers in one cabinet	minimal energy impact when conforming to ASHRAE 62-99 typical paybacks from 0 to 3 years by saving up to 80% in annual operating costs reduces heating, cooling and humidification loads up to 75%
Sloped drain pans	Positive drainage of condensate moisture	no standing water, eliminates microbial growth build up in drain pans
