Vacless Electrical Breathers provide immediate vacuum relief upon entrapment by allowing atmospheric air to rapidly fill the pump pot while simultaneously turning off the pump. Electrical units include a three minute time delay restart and audible alert.

Can replace Stingle SR-500 SR500

Breather 3 Features
Meets the requirements of ANSI / ASME A112.19.17 and complies with ANSI / APSP-7
Sequence of Events – Breather 3 Electrical Automatic or Manual reset
Vacless Electrical Breathers provide immediate vacuum relief upon entrapment by allowing atmospheric air to rapidly fill the pump pot while simultaneously turning off the pump. Electrical units include a three minute time delay restart and audible alert.
The pump starts and runs the normal filtration cycle using 110VAC, 220VAC or 3 PH power supply. After 15 seconds, utilizing a delay relay, a 5-10V DC circuit becomes energized. Upon entrapment, the vacuum level inside the pot is elevated creating a differential pressure across the seal. Atmospheric air pushes the seal compressing a spring until the O-Ring crosses grooves that allow atmospheric air to rapidly fill the pot making the pump loose prime quickly freeing the entrapment. The entire travel of seal occurs within milliseconds causing the shoulder to strike a pin plunger of a snap acting normally closed electrical switch to the open position. The plunger will spring back momentarily to normal operating condition. As the plunger is depressed, the 28V DC control circuit becomes open and causes a normally closed switch to open and turn the pump off. To prevent false shutdown of the pump during start-up surges the 5-10V DC control circuit is equipped with a delay relay. This relay is responsible for postponing the energizing of the 5-10V DC transformer and precludes switching off the pump even if the plunger is depressed.
