Specification Sheet

Unlike other products which are empty vessels or include only a baffle plate, the Spirovent Quad combines the features and benefits of the industry-leading Spirovent air eliminator along with the Spirotrap dirt separator. The coalescing element and dirt separation medium completely fill the internal volume of the vessel, providing unsurpassed efficiency. Connections have been engineered and placed to allow for the ultimate in hydraulic balance. The unique construction of this combined unit allows for the removal of both entrained air and dirt particles. The patented Spirotube, the core of the Spirovent Quad, creates a low velocity area in the Spirovent core that allows removal of 100% of the free air, 100% of the entrained air, and up to 99.6% of the dissolved air in the upper chamber. The lower chamber allows the dirt particles to sink with 80% of those 30 microns and larger removed within 100 passes. Dirt and sediment sink to the bottom of the unit and collect in the dirt chamber, eliminating any blockage concerns. The dirt can be flushed through the drain while the system remains fully operational, and the large collection chamber ensures infrequent flushing.
