4900 Series Commercial Air Separators Taco 4900 Series ® Commercial Air Separators help you save money and prolong the life of system pumps, piping and components by removing air and dirt from the system to prevent problems such as reduced heat transfer, loss of efficiency, pipe corrosion, pump damage, noise and the waste and cost of increased energy consumption. Patented PALL ring technology clears the system of micro-bubbles as small as 18 x 10 -6 meters, sand, dirt and rust. Through the use of our Pall Ring design, the 4900 Series ® Commercial Air Separators uses coalescence to collect and merge micro-bubbles on the surface of the pall rings and allow them to vent through the integral vent mechanism at the top of the vessel. The Pall Rings stop the momentum of dirt particles allowing them to fall to the bottom of the vessel and be blown down by the integral full port blow down valve. These are great for systems with both variable speed and constant flow requirements. Taco 4900 Series ® Commercial Air Separator feature test results from a 3rd party independent testing agency so you can be confident in the performance results of our 4900 models. Taco 4900 Series ® Commercial Air Separator Tanks are designed, constructed and tested to ASME Section VIII, Div. 1 requirements. Computerized product selection helps you choose the Air or Air/Dirt Separator Tanks that is just the right fit for your application requirements. All fabrication is done in-house to assure a high level of quality.
