Inquiry (采购产品): vacuum air pressure switches I am interested in finding a switch which will operate with a small differential in residential house pressure created by exhausting fans and appliances which would control a fresh air butterfly damper and the HVAC blower fan. What do you have. **** Hidden Message ***** Paul Pohl 4631 Smoke Rise Ridge Blairsville, GA 30512 USA Company: Radcliffe Phone: 706-781-4502 Fax: 706-781-6506 E-mail: pep4631@alltel.net **** Hidden Message ***** pep4631@alltel.net
