Make up air – passive solution?
I will be implementing a Broan ERV140TE ERV system during my build however this system is not intended to introduce additional fresh air when turning on additional negative pressure producing devices such as a kitchen hood or bathroom fans.
I’ve seen plenty of solutions utilizing motorized dampers which turn on in conjunction with the negative pressure device such as a kitchen hood exhaust but it would be nice to keep it simple and avoid those mechanicals. Is it truly the best solution? I’m wondering if a passive make up air solution exists as to avoid electric motors and circuitry to operate said dampers?
Would it make sense to install something like a Dundas Jafine BPSH4WZW in reverse or could high wind simply blow it open?
