VACUU•LAN networks are modular in several ways. One aspect of modularity is that the vacuum needs only be installed where the need exists today. A VACUU•LAN network can be installed as needed today, with additional vacuum capacity added after the fact when a need for vacuum is determined in a new location. This contrasts with central vacuum systems, which are inherently inflexible. Central vacuum systems are plumbed using large diameter piping located behind walls and between floors. That means that piping needs to be plumbed to every possible room where vacuum may (or may not) one day be needed, with pumps and piping diameters selected to accommodate the highest possible future flows. This overbuilding is expensive initially, and leads to higher than necessary operating costs for the life of the building.
Another aspect of the VACUU•LAN networks’ modularity is in the performance options for each vacuum workstation. Each port has a common mounting base that can accept a range of controls from a simple on/off ball valve, to a manual valve that provides variable flow control, to a solenoid valve that can be operated with a VACUUBRAND electronic controller for full programmable control of individual ports on the network. Ports can be upgraded or traded among locations in a laboratory as needs change, based on the modularity of the vacuum port design.
