Variable displacement vacuum pumps can provide over 20 inHg (68 kPa) vacuum. Their straight through, no-clog design is ideal for very dusty and dirty applications such as big filling or handling ceramic or masonry products.
The square body with two mounting holes make the variable displacement pumps easy to attach to any flat surface.
A straight through silencer option will not accumulate dust or debris and will pass it out with the exhaust air.
