With a Thermostat-Controlled Cabinet Cooler System, EXAIR uses a thermostat and solenoid valve to control the temperature inside an electrical panel.

Here is the video to go along with Neal’s blog post from December 17th. In case you missed that blog, an Electrical Contractor attached a 4″ Line Vac, Model 6087, to an underground conduit. At 80 PSIG the Line Vac was able to blow string through a 120′ conduit in less than 30 seconds. The contractor could then use that string to pull wire through the conduit.
