AP-01Z-10

The AB-CO PURGE Model AP-01Z-10 Purge and Pressurization System is a Z-Type system designed specifically for small electrical enclosures with volumes up to 10 cubic feet (0.28 cubic meters).  As a Z-Type purge and pressurization system, the Model AP-01Z-10 reduces the classification within the electrical enclosure used in a Class I, Division 2 (Groups A,B,C,D) and Class II, Division 2 (Groups F&G) hazardous environment from Division 2 to unclassified.

It supplies the enclosure with the proper amount of inert gas or clean instrument air which removes flammable gases and prevents the accumulation of ignitable mixtures within the respective protective enclosure.  In addition, this AB –CO Purge system is a very economical way to place unclassified equipment into a Division 2 hazardous location.  The Model AP-01Z-10 regulates and monitors the continuous flow (0.5 to 15 SCFH) of inert gas or clean instrument air into the electrical enclosure which can eliminate problems like heat, moisture, dust and corrosion within your enclosure.  It is ruggedly constructed of 316 SS control panel and ¼ inch O.D. 316 SS tubing.

It is also supplied with a vent (Model AV-1BG) that is used with the integral relief valve.  If required, an optional explosion proof pressure switch (Models DP-1A, DP-1B, or DP-1C) is available which can provide either audio and/or visual indication of a loss of purge (see details on specification section of this data sheet).

A heavy gauge stainless steel mounting bracket, a ¼-inch tube fitting for the cabinet, and an enclosure warning label are supplied with this unit.  The installer is responsible for providing the ¼-inch tubing from the Model AP-01Z-10 to the electrical enclosure.

This unit is certified by UL and approved by FM to meet the NFPA 496 Standard (Standard for Purged and Pressurized Enclosures for Electrical Equipment).

Note:  See Model AP-01Z-02 for small enclosures with a maximum volume of 2 cubic feet (0.056 cubic meters).
