Kitchen Exhaust Fans - Greenheck Exhaust Fans

Greenheck is the leading supplier of air movement and control equipment that includes fans, dampers, louvers, kitchen ventilation hoods, and energy recovery and make-up air units. Greenheck exhaust fans are used in all types of domestic, commercial, institutional, and industrial buildings in applications from comfort ventilation to manufacturing processes.

The Ceiling and Cabinet Fans include both direct and belt driven fans. The fans have forward curved wheels for low sound and high efficiency. They are suitable for clean air applications such as bathrooms, storage rooms, meeting rooms, or offices.

Ventilating a building simply replaces stale or foul air with clean, fresh air. Although the ventilation process is required for many different applications, the airflow fundamentals never change: Undesired air out, fresh air in. The key variables that do change depending on applications are the fan model and the air volume flow rate (cfm). Other considerations include the resistance to airflow (static pressure or Ps) and sound produced by the fan (Sones). Occasionally, a customer will require a fan to perform a particular function, yet does not know which model to use or even what cfm is necessary. In this case, some fan specification work must be done.

Exhaust fan specification is usually not a precise science and can be done confidently when the fan application is understood. Based on the application, four parameters need to be determined. They are:

Greenheck bathroom exhaust fans all perform the basic function of moving air from one space to another. But the great diversity of fan applications creates the need for manufacturers to develop many different models.

Direct drive fans are economical for low volume (2000 cfm or less) and low static pressure (0.50 in. or less). They require little maintenance and most direct drive motors can be used with a speed control to adjust the cfm. Belt drive fans are better suited for air volumes above 2000 cfm or static pressures above 0.50 in. Adjustable pulleys allow fan speed and cfm to be adjusted by about 25%. High temperature fans (above 120°F) are almost always belt driven.

Propeller fans provide an economical method to move large air volumes (5,000+ cfm) at low static pressures (0.50 in. or less). Motors are typically mounted in the airstream which limits applications to relatively clean air at maximum temperatures of 110°F. Centrifugal fans are more efficient at higher static pressures and are quieter than propeller fans. Many centrifugal fan models are designed with motors mounted out of the airstream to ventilate contaminated and high temperature air.

Fan models are designed to be mounted in three common locations: on a roof, in a wall, or in a duct. Whatever the location, the basic fan components do not change. Only the Greenheck exhaust fans housing changes to make installation as easy as possible. Determining the best location for a fan depends on the airflow pattern desired and the physical characteristics of the building. By surveying the building structure and visualizing how the air should flow, the place to locate the fan usually becomes evident.
