A wide range of flowrates covered by these blowers
This company manufactures API 672 integrally geared turbo blowers and multistage centrifugal-type blowers covering a range from 500 to 90,000 ft3/min for air, gas, pressure and vacuum. The LS Series multistage turbo blowers (photo) are available in sizes from 30 to 3,000 hp, handling pressures from 2 to 25 psig and flowrates of 300 to 45,000 std. ft3/min for air or gas. The multistage turbo blower is designed to operate with variable frequency drive control. Each model can be built from one to ten stages, and direct coupling means no gears or belts are required. Many impeller designs can be mixed to maximize efficiency. Compared to alternatives, the blower is said to cover a 30% greater pressure range and is 5 to 7% more efficient. Control options are available to meet any area classification (Class 1, Div. 1 to Zone 0 or Atex certified). — Lone Star Blower, Inc., Houston
