H&H 800

The H&H800 manual multifunctional negative pressure unit is a basic device designed for residential renovations. Intended for dust control in areas smaller than 40 m² (100 m³), which allows for approximately 6 air changers per hour.

Due to its versatile accessories and range of filters, H&H 800 is well-suited for air filtration, depressurization, odor neutralization, and for temporary ventilation.

Features

Continuously adjustable level of negative pressure – the negative pressure level of the device can be adjusted to the desired level, thus preventing excessive negative pressure, and minimizing the consumption of energy and the production of noise

Monitoring the condition of the filters – the orange warning light is lit when approximately 10% of filter capacity remains – the red warning light is lit when filter capacity is fully spent

Monitoring of negative pressure requires an add-on device – separate precision pressure gauge HHPM1 or datalogger GDUA

Easy and effortless operation – switch the device on, adjust the level of negative pressure with the adjustment wheel using the precision pressure gauge HHPM1, and monitor the condition of the filters with the warning lights

Multifunctional – suitable as is for use as an air filtration device, can be used both inside or outside the renovated area, in which case the area can be depressurized using suction connector assemblies and hoses. Combined with a mixing hood and a transport and mixing cart to use as a mixing station. Filter range includes G3, G4, F7, H13, and H14 graded filters, as well as G4 active carbon filters.
