DW 57 is an air driven mortar spraying instrument specially engineered for building site rendering tasks. Matching with compatible air compressors, it greatly raises work efficiency and cuts down physical labour compared with traditional manual plastering. Distinct from DW 55 and DW 56 straight up hopper layout, it features a unique slanted funnel structure, bringing superior material flow performance especially for ceiling overhead spraying. Its tank is made of aluminum alloy while critical shell sections adopt stainless steel material, securing solid durability amid tough construction site environments. A full set of four interchangeable spray orifices is supplied to adapt for diverse rendering media and different compressor outputs, perfectly fitting conventional plaster application scenarios. Its compact overall dimension supports operation inside narrow work zones; users only need to squeeze the control lever to trigger spraying output. The extended operating handle can be detached entirely for easy field transportation and space saving storage.
Unique Slanted Angle Funnel Structure
Specially tilted hopper design optimizes internal material flow path. It reduces material residue and sediment buildup when users perform large scale overhead ceiling spraying operations.
Aluminum Stainless Steel Composite Framework
Aluminum alloy material reservoir paired with stainless steel outer housing. Excellent rust-resistant capability against wet mortar, plaster and cement based compounds for long term site service.
Four Piece Interchangeable Orifice Kit
Four separate orifice accessories are included. Users can swap components to fit varied coating viscosity and different air compressor capacities for regular plaster rendering assignments.
Detachable Extended Reach Operating Handle
Long working handle supports full disassembly. Remove it for compact carrying and storage; install the complete handle assembly to reach elevated wall and ceiling surfaces conveniently. Light weight whole-unit design relieves operator fatigue during continuous shifts.
Simple Lever Controlled Spraying Operation
Material ejection gets activated simply by pressing the hand lever. Reliable spraying output can be achieved even in cramped corners and confined construction spaces.
Product Overview
DW 57 pneumatic mortar hopper sprayer is an efficient time saving construction tool widely deployed for building refurbishment projects. When connected with air compressors, it can process plaster, cement mortar, ground mixed coating and many other construction texture compounds. It fits multiple working scenarios including gypsum board composite treatment, textured paint spraying, ceiling decorative texturing, old property renovation as well as waterproof layer spraying. Each complete package contains slanted angle hopper body, detachable long handle and four piece orifice group, ready for direct onsite deployment.
