Axial fan Model H

ceiling-mountedfor air circulationdestratifier

Overview
Reznor® Destratification Fans circulate warm air from high-level zones down to the occupied floor level, reducing thermal stratification to lower heating demand and improve occupant comfort. Model H is offered in four sizes sized for maximum mounting heights from 25 to 60 ft and is suitable for spaces approximately 10 to 60 ft high. During warm periods the unit can provide gentle airflow to reduce perceived temperature and cooling load.

Design & Installation
Model H units support multiple mounting methods: two-point suspension with threaded rod, Reznor side mounting brackets for vertical or angled attachment, and front directional louvers for airflow aiming. Units include provisions for simplified control wiring, service access, and safe installation practices.

Standard Features & Benefits

• Redistributes existing space heat to occupied levels, reducing heating load and improving building energy performance
• Provides cooling air movement to enhance occupant comfort during warm periods
• Engineered for spaces with heights from 10 to 60 ft to effectively drive air to the floor
• Compatible with common building electrical systems — low amp draw axial fan motors
• Adjustable airflow direction via side brackets and front directional louvers
• EPACT-compliant axial fan motors for reduced energy use
• Close-mesh fan guards for safe operation
• Lightweight construction with external control and power connections for easier installation and servicing
• Neutral styling to integrate with ceilings and complement Reznor unit heaters

Optional Features

• Multiple voltage options: 120V/1ph, 208V/1ph, 230V/1ph, 240V/1ph, 277V/1ph
• Remote occupied/unoccupied (on/off) switch for manual control
• Multi-unit controls enabling zoning for up to 5 units
• Internal temperature control to run the unit only when required
• Single-stage thermostat for simple temperature-driven control
• Dual-stage thermostat to coordinate unit heater and destratification operation
• BACnet-linkable thermostat for Building Management System (BMS) integration
• Thermostat protection and mounting options

Installation Notes
Integrated louvers and directional side brackets allow targeted airflow around obstacles such as racking or mezzanines. Side mounting brackets support vertical or angled installation. Units are lightweight and provide external power and control terminations to simplify wiring and maintenance.
