Joshua IV Series 100 Commercial Kitchen Ventilators with Removable High Efficiency Extractor Inserts

Principles of Operation:

The high velocity, low volume design of the JOSHUA IV SERIES 100 VENTILATOR captures and removes smoke, grease, heat (convected), dust, lint and odors that are produced by cooking operations in the kitchen area. This cleansing action of the exhaust air greatly reduces the potential fire hazard and maintenance problems caused by the accumulation of greasy flammable material in the exhaust ductwork.

The filterless extraction system of the JOSHUA IV is comprised of a series of fixed baffles running parallel to and throughout the entire length of the ventilator. The baffles are mounted to removable panels (referred to as "HE" inserts). These "HE" inserts are of a convenient length (either 14" or 19") to allow easy removal by maintenance personnel. A commercial dishwasher may be used to thoroughly clean the "HE" inserts.

Components:

The JOSHUA IV consists of three basic parts:

1. a grease extractor section;
2. a ventilator canopy;
3. a fire damper assembly.

Standard Construction:

All JOSHUA VENTILATORS are constructed entirely of type 304 stainless steel. The grease extractor section is #16 gauge stainless steel and the ventilator enclosure is a minimum of #18 gauge stainless steel with #16 gauge stainless steel ends. The canopies of either single or double island units are finished on all four sides.

Styles:

The JOSHUA IV is available in several styles to accommodate either island or wall type-cooking layouts. Full length integral supply air is offered in different configurations as an option on all JOSHUA Series Ventilators:

1. internal short cycle;
2. low velocity, perforated front discharge;
3. fixed registers for front or downward discharge.

Fire Damper Assembly:

The fire damper is a #12 gauge stainless steel U.L. listed assembly activated by a fusible link device. In the event of a fire condition, the fire damper will close thus sealing the exhaust duct opening to prevent the spread of the fire through the duct system.

This assembly is also available with optional fusible link activated damper with fan shut-down capabilities or totally electrically activated damper assemblies. Fusible link damper assemblies are optional for supply air collars.
