A&A Gamma 2 Venturi Pop Up Head - BlackThe A&A Gamma Series 2 is an upgraded version of the original A&A Style 2. Introduced mid-2012 the Gamma 2 utilizes a bigger locking tab to guarantee a seamless fit into your existing Style 2 Collars. Easily diagnose or install these cleaning heads with the A&A Style 2 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!
