The ability to control the flow of materials has been a staple in human civilization since 4000 BCE. This includes the creation of pipes which have appeared as early as 2400 BCE from the Egyptians. These piping systems have since then been improved on to be made stronger, lighter, cheaper, of various styles, and in a variety of materials. One of these styles is the sanitary flange pipe.
Sanitary flange pipe and fittings is one of the larger milestones in piping innovation. Sanitary flange pipes came about due the stringent cleanliness controls in certain industries such as food and pharmaceutical. Both of these use a highly corrosive and caustic soap to sanitize surfaces and, in most cases, entire rooms. Sanitary flange pipes allow for pipe systems to be taken apart easily so that components can be easily cleaned out on a regular sterilization process, and are generally made of 316 Stainless Steel to withstand the corrosive nature of the cleaning compound.
EXAIR Line Vac Air Operated Conveyors have always been well suited for these applications since the internal components are smooth and can be cleaned out easily and sanitized. They have also been made out of 316 Stainless Steel for years which provides superior corrosion resistance and can withstand most caustic cleaners and oxidants. Type-316 Stainless Steel is the preferred material for many food and pharmaceutical applications. Before EXAIR’s Sanitary Flange Line Vac, we noticed our customers would use the standard smooth Line Vac and weld a sanitary flange onto the ends, or installing adaptors on our Threaded Line Vac.
With that thought we decided to make things easier and developed the Sanitary Line Vac which follows the basic design of the Standard Line Vac and operates with the same performance characteristics. Sanitary Flange Line Vacs come in four sizes: 1-1/2”, 2”, 2-1/2”, and 3”. These sizes are the most common sizes for Line Vacs and covers the majority of application needs.
