The Verti-Press VPC filter is the best due to its automated pre-coating and filtration cycle which employs a permanent media filter belt. This eliminates the use of disposable paper products, which reduces landfill wastes. In addition the Verti-Press has the ability to produce product that meets the ASTM Cold Soak Test, which allows the end user the assurance that they are providing the highest quality biodiesel product to their customers.
