Mark VII-N Autoclave Sterilizer & Compactor

Integrated High-Capacity Waste Treatment

Is the Mark VII-N Right for Your Facility?

The San-I-Pak Mark VII-N is designed for facilities that need a modular, integrated onsite treatment system with higher processing capacity, hands-off loading, and built-in waste compaction.

The San-I-Pak Mark VII-N combines steam sterilization, automated cart loading, waste discharge, and high-density compaction in one modular system.

Its three-position process—load, sterilize, and dump—supports a controlled workflow from collection through final compaction. With a listed processing capacity of 400 pounds per hour, the Mark VII-N is suited to facilities managing larger volumes of regulated medical waste.

The system is available in left-hand and right-hand configurations, allowing the equipment orientation to better accommodate the facility’s available space and operational layout.

The Mark VII-N integrates waste loading, steam sterilization, discharge, and compaction within one coordinated footprint.


An integrated cart dumper supports hands-off loading, while the system’s high-density compactor reduces the volume of treated waste. The Mark VII-N can manage regulated medical waste and municipal solid waste within the same system footprint.


The unit can be installed either indoors or outdoors and is available in left-hand or right-hand equipment orientations.
