RONDA NPU 1250 is a handy and effective negative pressure unit for the small jobs. The machine reduces the amount of airborne dust particles and creates a negative pressure inside the working space, preventing the dust from spreading to other parts of the building. Thus RONDA NPU 1250 contributes to a good working environment at for example demolition-, asbestos removal-, and renovation tasks.

The machine is equipped with a large pre-filter, which captures most of the airborne dust particles. Furthermore, a HEPA-14 filter holds back the finest and most health-hazardous particles. The filter load is monitored through a manometer which shows the pressure drop across the filters when the machine is operating.

RONDA NPU 1250 is a so called overpressure unit. It is constructed in a way that ensures a constant overpressure inside the fan unit- and electrical compartment. This is a major advantage when dealing with health-hazardous dust such as asbestos fibres, as cleaning and maintenance of the machine is much easier because the health-hazardous particles cannot get into the fan unit and the fan unit compartment.

We recommend placing the RONDA NPU 1250 in a screen wall or another type of opening. Alternatively, you can place the machine inside the working area and then have a Ø315mm ventilation hose lead the exhaust air outside. An adapter is delivered with the machine for coupling a hose to the intake side as well, and with a transport cover to seal the negative pressure unit during transport.

Four strong wheels – two of them lockable – and four lifting handles make RONDA NPU 1250 easy to move around.
