50-70m3/h Filter Housing

This type of housing is generally mounted at the suction and extraction points outside the main ventilation-filtration network of a glove box operating in depression. The essential function of these boxes is to provide high-security double filtration for those nuclear enclosures and glove boxes designed for handling powdered toxic products.

Technical Specifications – Information

Technical specifications of the 70m3/h filter casing:

New model, entirely made of AISI 304L stainless steel. Removable housing and the HEPA 50 or 70m3/h filter can be replaced by unscrewing the upper part.

Sealing tested with a helium mass spectrometer and oxyleak class 1 ISO 10648-2.

ISO KF DN50 inlet/outlet connections.

Supplied with a round bag and bag for replacing the internal filter with a heat-sealable bag.

Option: filter clogging control (G ¼’’F connections).

We talk about double filtration because the same HEPA filters are mounted in series at the intake and at the extraction inside the enclosure. For glove boxes operating under air, the filter boxes also provide protection against shocks and allow for easy connection to a general extraction network. For glove boxes operating in negative pressure under neutral gas, the filter boxes are connected in this case either to a semi-open ventilation system, or to a closed loop neutral gas purification system. In special cases, depending on the required flow rates, they are used for the filtration of the process circuits of instruments and special machines.
