Vacuum Pumps

Rotary Vane Pumps: Uses oil-sealed rotating blades; the most common choice for general and HVAC work. Liquid Ring Pumps: Uses a rotating liquid ring to seal and compress gas, highly resistant to dust and moisture. Dry Pumps: Operates without fluid in the compression chamber, avoiding oil contamination in sensitive environments. Roots Blowers (Boosters): Moves high volumes of gas quickly but requires a backing pump to handle final compression.
