    Red Alert P101-2 Control Panel

    Product Video

    The Red Alert P101-2 Control Panel is a superior replacement for panels used with septic tank aerators. This control panel is compatible for use with air pumps, vane pumps, regenerative blowers, and linear style aerators manufactured by brands such as Whirlwind®, Hiblow®, Gast®, Secoh®, as well as alternative high-quality replacement units like the ones produced by Septic Tank Parts. This unit is not to be used with shaft-style aeration systems.

    For shaft-style aerators, use the Red Alert P101FA-2 Control Panel.

    The Red Alert control panel is manufactured for longevity in indoor and outdoor use. Crafted from industrial-grade plastics, UL-rated weather-resistant housing, and anti-corrosive zinc-plated screw terminals, this control panel is resistant to wear and temperature extremes.

    With the Red Alert™ 24-time control technology, the P101-2 is completely programmable with a control timer, warning light, and a 3-position toggle switch that allows the unit to be on/auto; off; or in continuous run mode. The ability to program down to 15-minute intervals gives you precise control over your aerator scheduling.


    We offer a 2-year limited warranty on Red Alert Control Panels.
