Positive displacement pumps create a vacuum by drawing the air or gas from a chamber through the intermeshing rotary screws and discharging back to the atmosphere. This continuous process flow moves gas at a constant speed, making it a stable and reliable choice for many industrial applications. Vacuum pumps are highly reliable and efficient, produce low noise, and some types can be used in harsh environments.
In a direct-drive vacuum, the motor couples directly to the vacuum driveshaft to power the vacuum airend. Units range in size from 7.5 to 90 kW, delivering capacities up to 3,505 CFM. All vacuums feature a single-stage, rotary screw design and include our patented, low speed SKYv airend with variable discharge port and variable speed drive.
All direct drive models feature low-speed operation with a 1:1 drive ratio that eliminates transmission energy loss, as well as a patented SKYv airend and laminar inlet valve to deliver maximum power with minimal waste. Together, these features make our vacuums some of the most efficient on the market.
KRSV Industrial Vacuums feature premium components, such as 316 stainless steel tubing and quadruple discharge bearings, with a longer service life than competitors' duplex bearing designs. As a result, our products deliver reliable performance, year after year, with higher reliability and lower maintenance costs.
By combining power and reliability, our compressors help your operation stay up and running. Heavy-duty components and low speed rotating elements minimize wear and tear over time; a variety of cooling features, such as oversized air-cooled coolers, also maintain an ideal operating temperature to reduce the risk of overheating. Best of all, when routine maintenance is required, accessible components help keep downtime to a minimum.
Our direct drive energy-efficient compressor with patented SKY airend draws less power to meet your capacity requirements. Over the life of the compressor, even a small amount of increased energy efficiency adds up to significant cost savings. An energy-efficient air compressor is thus able to pay back a higher upfront cost of investment over the life of the equipment.
