Swam Pneumatics Pvt. Ltd. offer service "Mechanical Vacuum Booster"

These dry mechanical vacuum boosters use advanced construction for durability and performance: castings are FG-260 grade for better quality and made thicker than typical units to allow for corrosion, paired with an oversized shaft that in turn accommodates larger bearings. Each unit includes a minimum of six bearings, including two thrust bearings, all sourced from imported FAG/SKF stock, and a sealing arrangement built around special double metallic seals.
