Air Dimensions R254-BT-AA1 Dia-Vac Diaphragm Pump

Air Dimensions’ R254-BT-AA1 Dia-Vac Diaphragm Pump is a quad-head, high-vacuum Dia-Vac® pump in the R-Series designed for oil-free gas sampling and general vacuum tasks. Dia-Vac diaphragm technology provides oil-free, contamination-free, and leak-free operation, delivering reliable sampling performance in analytical and laboratory environments. The R-Series can be specified with multiple motor options, including General Purpose open-drip, TEFC, Brush-Type DC, Air Driven, and explosion/flame-proof configurations to suit different power, environment, and duty requirements. For reference, single-head R-Series pumps list up to 29.5 inHg ultimate vacuum and up to about 150 LPM (SLPM) flow, and the quad-head topology is intended to scale capacity while preserving the same oil-free, inert-gas handling characteristics. Common applications include gas sampling in analytical instruments, vacuum line evacuation, and controlled gas transfer in research or process settings. Model R254-BT-AA1 identifies a quad-head general-purpose variant within the Dia-Vac family.
