<p class="MsoNormal"><span style="font-size:11.0pt">Back in my time at Cornell, we starting installing lab-scale house vacuum systems for labs that needed them for vacuum chucks as well as some chemistry applications (<a href="https://www.vacuubrand.com/system-solutions/vacuulan-vacuum-networks">Vacuu-Lan</a>).
We were impressed with their capabilities and ultimate pressures they could achieve. They have lots of options and the pumps don’t run continuously, but cycle at variable speeds as required to maintain the vacuum setpoint. I can’t speak to their maintenance
and reliability, as most were installed right before I left for my position here, but the short time I worked with them I was impressed by their build quality. One point was that they indicated you really need to use their vacuum fixtures with the system,
as they have check valves in them to prevent backflow from one connection to another. The connections and runs are easy to do as they use flexible tubing instead of hard pipe that is common with other house vacuum solutions (which was a change for our architect
/ engineer lab design teams and contractors).<o:p></o:p></span></p>
