Electro Industries’ Packaged Make-Up Air units are designed for today’s tighter homes where unhealthy negative pressure can be created by appliances such as kitchen vent hoods, fireplaces, dryers, gas furnaces, water heaters, bathroom exhaust fans or any appliance without sealed combustion.

These high efficiency units provide fresh air to keep the home or building at positive pressure, reducing backdrafting combustion gasses that could create a health risk.

International Residential Code (IRC) requires exhaust hood systems of 400 CFM and greater to have make-up air equal to the exhaust air and to automatically open and close with the operation of the fan.

  • WarmFlo® Digital Proportional Temperature Control – utilizes full element modulation with solid state relay, inlet and outlet temperature sensors, to maintain precise user defined temperature set point
  • Integrated powered inlet damper
  • Aluminum mesh permanent washable filter
  • All models include (1) CT “doughnut”
  • Simple installation, mounting kit included
  • Listed for horizontal or vertical installation

Electro’s Industry Exclusive Features of 5-22 kW Models:

Electro’s unique control adapts to multi-speed range hoods or multiple fan applications:

  • Multiple Fan Speed Output – Low, Medium, and High fan speed output to match multi-speed range hoods.
  • Multiple Control Input Options – Three current transformer (CT) inputs allow for multiple fan applications.  CT inputs will also provide variable blower speeds to more closely match multi-speed exhaust fans.  Activation can also be as simple as an end switch or contact closure.
