Model YZ101A Universal Mount Purging & Pressurization Unit

Brand: Best Purging Systems Corporation

Model YZ101A is a Type Y or Z pressurization unit designed to protect electrical equipment in Class I and Class II Hazardous Areas.

When connected to a supply of protective gas, the Model YZ101A will supply, regulate and monitor the protective gas supply to a protected electrical enclosure.

Type Z applications reduce the hazardous area rating inside the enclosure from Division 2 / Zone 2 to Unclassified.

This allows general purpose equipment to operate in Division 2 / Zone 2 areas.

Type Y applications reduce the hazardous area rating inside the enclosure from Division 1 / Zone 1 to Division 2 / Zone 2.

This allows Division 2 / Zone 2 equipment to operate in Division 1 / Zone 1 Hazardous Areas.
