Pneumatic PU Spray Foam Machine

Description

This polyurethane spray foam machine provides a combined material proportioning, heating and delivery system for compatible two-component PU applications. It is intended for contractors carrying out spray foam insulation work, including roofing projects using suitable closed-cell foam formulations. The machine delivers the A and B chemical components at a specified 1:1 output ratio. This makes it suitable for material systems designed for that proportioning ratio. The selected foam formulation must match the machine’s capabilities and the requirements of the application. A pneumatic drive powers the pumping mechanism, while the electrical heating system provides 7.5 kW of heating power. These functions support material preparation and delivery to the spray gun. The machine requires an appropriate compressed-air supply; the required air pressure and consumption were not stated in the supplied specification sheet. The listed material output range is 2–12 kg per minute, with a maximum working pressure of 11 MPa, equivalent to 110 bar. Actual output depends on the material, operating settings, spray gun configuration and hose arrangement. These figures provide a reference for assessing the machine against the intended workload. The standard configuration includes one spray gun, two transfer pumps and a 15 m hose. The transfer pumps feed the two components into the system, while the spray gun provides the application point. The machine supports a maximum hose length of 90 m, although additional hose beyond the standard 15 m is not listed as included. The illustrated unit has a wheeled frame, handling points and a front-mounted panel containing controls and gauges. This arrangement allows the machine to be positioned at a suitable work station while the hose extends to the spraying area. Its overall dimensions are 75 × 54 × 112 cm, and the stated machine weight is 139 kg. Electrical supply options are listed as 110 V, 220 V and 380 V. The required configuration should be selected when ordering; these are supply options rather than confirmation that one machine automatically operates on all three voltages. For insulation contractors, this machine brings the principal spraying components together in a mobile format. Its suitability for a particular roof, wall or other substrate depends on the chosen PU formulation and the specified installation system. Foam density, thermal performance and finished thickness are material and application properties rather than fixed machine specifications.
