Fantech HERO 140E 142 CFM Energy Recovery Ventilator is backordered and will ship as soon as it is back in stock.
Tight residential construction keeps conditioned air in, but it also traps stale air and excess moisture inside. The Fantech HERO 140E Energy Recovery Ventilator addresses that tradeoff by continuously exchanging indoor and outdoor air while recovering some of the energy your HVAC system already used to condition it.
Beyond daily comfort, this ERV supports compliance with major residential energy programs, including Energy Star Certified Homes, DOE Zero Energy Ready Home, and LEED for Homes.
Key Features and Benefits of the Fantech HERO 140E 142 CFM Energy Recovery Ventilator
- Variable Airflow: Rated with an adjustable airflow range from 50 to 142 CFM at 0.4 inches w.g. static pressure, this model lets you match ventilation precisely to your home's occupancy and layout.
- Counterflow Core: Achieves up to 79 percent sensible recovery efficiency at 32 degrees F, pre-conditioning incoming air so your HVAC system uses significantly less energy.
- HERS Impact: Reduces ventilation heating and cooling loads enough to gain approximately 3 to 5 HERS Index points (depending on the climate), with the largest benefit in extreme climate zones.
- Filter Options: Includes a washable MERV 3 filter, but supports an optional MERV 13 filter to capture fine particulates such as PM2.5 and allergens, with a standard MERV 8 filter also accepted.
- Electronic Controls: Variable-speed electronic operation draws up to 167 watts, giving you precise airflow adjustment while keeping continuous energy consumption low.
- Top Port Drainless Design: Top-mounted 6-inch round duct connections with rubberized gaskets on metal collars and a drainless design allow the ERV to fit into compact spaces and tight closets.
- Balancing Taps: Integrated manometer ports let your contractor read pressure drops and balance supply and exhaust airflows quickly during commissioning.
- Certified Performance: Carries HVI and Energy Star certifications alongside a CSA listing, so published airflow and efficiency figures meet independently verified standards.
Fitting the HERO 140E Into Your Mechanical Space
Before you commit to a mounting location, verify that your mechanical closet or utility room can accommodate the HERO 140E footprint. This ventilator measures 24.88 x 27.88 x 15.38 inches (H x W x D) and weighs 59 pounds, so you will need solid wall framing and clearance above for duct routing. With no condensation drain needed, your installation site options expand to closets and utility areas that lack floor drain access.
Sylvane's Expert Take
If you're a contractor or builder specifying ventilation for a tight residential build, the HERO 140E ERV earns its place in the mechanical plan. A standard exhaust-only strategy pulls conditioned air out of the envelope without recovering any of the heating or cooling energy behind it. This ERV's variable-speed counterflow core returns that energy to the incoming supply, which can allow you to spec a smaller furnace or air handler while still meeting Energy Star and ZERH ventilation requirements. The drainless, top-port design is the real time-saver on-site, because you can mount it in a compact closet without routing a condensate line.
