Spirotech BC Range of Combined Air & Dirt Separators Standard Flow units up to 1.5 mtrs/sec velocity

All Air & Dirt Separators must create the correct environment to be able to work efficiently. The Spirotech brand uses a separation element constructed of spirally wound copper wire around a central copper core. This arrangement creates an area of laminar flow (static water) at the top and base of the unit enabling even the smallest of microbubbles and dirt particle to overcome the mass flow of the circulating fluid and then simply collect at the top (Air) or base (dirt) of the unit. It is the only point on the system where laminar flow exists when in normal operation.

However, if the flow rates are excessive the whole of the separator may become turbulent hence no laminar flow may exist, therefore it is necessary to provide some “guidance” as to the maximum flow for each size of unit. The chart below provides the required information to assist with product selection at a velocity of 1.5 mtr/sec.
