The b&m A 4000 VP is a high-pressure device with a working pressure of up to 230 bar. The appliance is optionally available in aluminum or stainless steel. VA is the material of choice for a long service life, especially when alkaline or aggressive media are used. Can be used on any construction site without additional compressed air thanks to the power supply connection. The devices are ideal for injecting or repairing cracks with PUR resins, epoxy resins, silicates, sponge protection agents and wood preservatives. An inlet valve with valve dabber simplifies commissioning, even if the valve cone should become stuck. The working pressure is steplessly adjustable from 0 – 230 bar on the pressure regulator of the appliance.
