Solid by-products can harm your vacuum booster. They accumulate and cause damage to the lobes. Solid by-products can bring production to a standstill. To prevent this, we literally shave them off by incorporating scrapers into the lobes of our vacuum boosters. With every turn, these little knife blades scrape away any harmful build-up of solids. Now, potentially damaging material has no chance of gathering to the point where it clogs the vacuum booster. It is carried into the backing pump in a size that is manageable, even for smaller pumps. The result: Your vacuum booster runs smoother and lasts longer. Plus, longer maintenance intervals and less costly downtime. Simply shave away your costs!
