NVENT HOFFMAN A1001YZUMC1 Small-volume system, class 1
nVent HOFFMAN A1001YZUMC1 small-volume Type Y and Type Z purging and pressurisation system designed for Class I hazardous location enclosure applications.
Why Choose the nVent HOFFMAN A1001YZUMC1 Small-Volume System, Class 1?
The nVent HOFFMAN A1001YZUMC1 Small-Volume System, Class 1 is a Type Y and Type Z purging and pressurisation system designed to enable the use of general-purpose enclosures in certain hazardous location applications. This compact system regulates and monitors enclosure pressure using compressed instrument air or inert gas to help prevent flammable gas, vapour or combustible dust accumulation.
Designed for hazardous area protection applications, the A1001YZUMC1 provides an alternative solution to NEMA Type 7 or Type 9 explosion-proof enclosures. The system is suitable for protected enclosures with a maximum volume of up to 2 ft³ (0.06 m³) and supports Class I hazardous location requirements.
Featuring a universal mounting design, a Type 316L stainless steel mounting plate and an integrated tamper-proof regulator with gauge, the nVent HOFFMAN A1001YZUMC1 provides reliable enclosure pressurisation control for industrial environments where hazardous location compliance is required.
