Ultimate Air vs. Zehnder HRV

I recall seeing in the comments for the article discussing a new way to duct hrv's that one of the Zehnder reps was disparaging the Stirling Technologies Recoupaerator 200dx for having something to the effect of misleading, incorrect, etc. performance numbers and that it does not stack up to Zehnders products. I was wondering if that rep and anyone else could clarify why the Zehnder product would be better than the 200dx and how they differ in function? The cost of the 200dx is significantly less.

What is mechanical ventilation

A mechanical ventilator is a machine that generates a controlled flow of gas into a patient’s airways. Oxygen and air are received from cylinders or wall outlets, the gas is pressure reduced and blended according to the prescribed inspired oxygen tension (FiO2), accumulated in a receptacle within the machine, and delivered to the patient using one of many available modes of ventilation. The central premise of positive pressure ventilation is that gas flows along a pressure gradient between the upper airway and the alveoli.

Welding ventilation systems

General Industry Before welding begins, all hollow spaces or cavities should be vented to allow air and gases to escape. Mechanical ventilation of at least 2,000 cubic feet per minute per welder should be provided for workplaces with a ceiling height of less than 16 feet, or that measure less than 10,000 cubic feet per welder. Movable hoods capable of providing an airflow rate of 100 linear feet per minute should be placed as close to the welder as is practical.

Beware These 3 Expensive Ventilation System Ripoffs How much does an exhaust fan cost? Search online and you can find lots of them that move 200 cubic feet per minute (cfm) for $100 to $150. But, if you put one in a semi-attractive (emphasis on the "semi") package, create some fancy marketing materials, and target people who don't know much building science, you can charge $1200 to $1700 for that same fan.
