One of the most critical components you will need for the vacuum system is the vacuum pressure controller. The device measures vacuum pressure inside of the reservoir. It turns the vacuum pump on when the pressure inside the tank drops below a given level and turns the pump off when the correct amount of vacuum is reached.

Important Notes

• The Type 1 version of this controller is the same unit we include in each of our auto-cycling vacuum press kits.
• I highly advise against purchasing a vacuum controller as the only component for making a vacuum pump cycle on and off. Instead, use the Project: EVS vacuum press kit which allows the pump to reliably, properly, and safely release the back-pressure from the pump when it cycles off. The Project: EVS kit is designed to protect the vacuum pump from stalling and over-heating.
• To mount the vacuum switch remotely, a connecting brass fitting is also available.
• If you are using a rotary vane vacuum pump, you must use a relay. Rotary vane pumps draw up to 3 times more amperage at startup than the name-plate shows. Most rotary vane pumps draw 6+ amps while running. This equals 18+ amps at startup which is too much for the vacuum controller to handle on its own.
