1 Exhaust air device for clean rooms SPWH, SPWV TECHNICAL DATA page 159 Exhaust air device for clean rooms SPWH, SPWV Exhaust air devices SPWH and SPWV for clean rooms are intended for ceiling or wall installation in premises where the requirements for very clean air are high, for example clean rooms, pharmaceutical industries, etc. SPWH has duct connection placed at the side of the terminal box and SPWV has duct connection positioned on the top. The device includes a HEPA filter of class H1 or according to PN-EN1822-1, which ensures a very high degree of filtration. Integral measurement sockets in the device mean that the pressure drop can be measured and that any filter leakage can be identified. Excessively high pressure drops across the filter also indicate that it should be replaced. SPW(H,V) is made of painted steel sheet, and its construction makes filter replacement quick and easy. On request diffuser can be also equipped with filter class H11.
