A&A Gamma 4 Venturi Pop Up Head - Euro BlueThe A&A Gamma Series 4 Venturi is an upgraded version of the original A&A Gamma 4. Introduced mid-2012, the Gamma 4 utilizes a bigger locking tab to guarantee a seamless fit into your existing Gamma 4 Collars. Easily diagnose or install these cleaning heads with either the Plastic Gamma 4 Tool or the Metal Gamma 4 Tool. When dealing with older heads that may be stuck in their fittings, we always recommend the Metal Tool. A&A has also made some improvements to the spring which allows the head to pop up fully when the pump is running at lower RPM's; a big plus for anyone who has recently switched over to a Variable Speed pump!
