Self-clean design With SOLOLIFT2 macerators there is no need for regular cleaning or heavy chemical cleaners thanks to the clever design of its grinder and tank. The grinder cleans itself after each operation using the water-air mix present, which is both natural and environmentally friendly. The design also ensures that no debris sticks to the tank walls, removing the need for extra filters and eliminating the risk of odour problems High torque, hardened steel cutter The durable steel cutter is reliable and effective, handling anything that is thrown at it on a day to day basis. External de blocking There’s no need to remove the unit or cover with easy external access for unblocking the blades. Clever tank design A special tank floor design ensures solids are guided swiftly and easily towards the pump.
