The Gamma Series 4 Venturi is an upgraded version of the original Gamma 4. Introduced in 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. Pentair In-Floor(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 RPMs; a big plus for anyone who has recently switched over to a Variable Speed pump!
The Gamma Series 4 Venturi uses pinholes on the top of the head to draw in extra water and add a cleaning boost for those hard-to-reach areas.
