Introduction de produit

This smallest negative-pressure model combines a 500 mm cubic work zone with a 660 x 500 x 590 mm external envelope. The 1.2 mm SUS304 enclosure uses a mechanical door interlock and controlled clean-to-contaminated airflow direction. It is intended for small contained articles leaving a clean area where inward leakage direction matters more than active positive-pressure protection of the load.

Key Features

Compact contaminated-side bias

The airflow direction is arranged toward the contaminated side to discourage release back into the cleaner room.

Small partition demand

The 660 mm external width preserves wall space around densely serviced laboratory rooms.

Simple mechanical sequencing

A mechanical interlock prevents simultaneous access without depending on an electronic door-control package.

Applications

For compact laboratory samples, sealed diagnostic packs and controlled waste moving away from a clean pharmaceutical, hospital or research space. The facility exhaust strategy and actual pressure relationship must be reviewed so the stated clean-to-contaminated direction agrees with the room cascade.

Solutions for Your Application

A positive-pressure pass box could push air in the wrong direction when the transferred item is the contamination source.Select the negative-pressure configuration so leakage is biased from the cleaner side toward the contaminated side.

A large active chamber would occupy excessive wall area for low-volume specimen transfer.Use the 500 mm work zone for compact loads and verify the complete load envelope before freezing the cut-out.

Options disponibles

Define exhaust connection, pressure monitoring, door handing, window arrangement and wall trim for the facility. Load disinfection and downstream waste handling remain part of the user's containment procedure.
