The latest evolution VS651 provides a range of advanced innovations as standardCost of OwnershipVS651 sweeper operates at the lowest cost, with a large190 litre auxiliary fuel tank giving increased on-station time. In addition, maintenance costs are significantly reduced on the Johnston gearbox and fluid coupling, as no belts or high wearing components are required. The Johnston VS651 provides the lowest emissions and running costs, both VT and VS models operate at low fuel consumption with both the chassis and auxiliary engines using a total of 5.05l/hr at low rpms. Suction sweeping requires fewer components, resulting in less wear and tear which in turn reduces maintenance costs.DurabilityDesigned to last in the toughest environments, the VS651 hopper is manufactured from 4003 stainless steel, shot blasted with aluminium oxide prior to the application of a strontium bases primer followed by a hard wearing top coat. In addition, all grey parts such as the sweepgear, powerpack and sub-frame are shot blasted and electro-magnetically powder painted in a durable two part epoxy paint finish. This ensures the sweeper continues to look as good as it performs, retaining a high residual value or longer in-service life.
