Unique cam locking mechanism prevents door(s) from being closed unless the filters are sealed.

Unipak is a safe-change containment system developed for the installation of high efficiency (HEPA) air filters in air intake and extract applications. Particularly suited for extract systems handling contaminated air, Unipak helps to protect maintenance staff and the surrounding environment from contamination when the filters are changed.

The Unipak system is a modular design based on standard pre-filter and final filter housings. They are available as canisters for installation in ductwork systems, or as containment systems manufactured by linking a number of housings together with inlet and outlet headers. Systems can be designed to customers specifications or supplied as individual housings for installation in a customers existing system if required.

Unipak systems have been proven to meet stringent requirements on the quality of air being supplied to, or extracted from, process areas in environmentally critical applications over many years. These include nuclear power generation, nuclear fuel reprocessing, biotechnology and pharmaceutical manufacturing.
