Chelmsford-based ventilator company ramping up production to battle coronavirus I heard about this while driving into the office this morning. There are 175 parts in this small portable ventilator. I've worked with a lot of the people assembling these in Chelmsford and wish them great success. But it will take weeks and months to get to that volume, so listen to people like Fauci and restrict interactions to those that are necessary. I've also seen emails going around where some service engineers are getting trained on servicing our company's ventilators. Servicing broken ventilators can be much quicker and use service designated parts for existing ventilators. Getting a larger team can decrease that turn around time and get these broken ventilators back in the game.
