Ecology unit are specifically designed for the removal of smoke, oil, and grease particles from kitchen ventilation systems, in order to eliminate odors, or at least minimize them to tolerable levels. It is essential to remove particulate matter from the kitchen area, for neutral exhaust air. This is an important element of the ventilation system that assists in the dispensation and elimination of effluents that are a byproduct of kitchen exhaust activity. These units provide a clean environment in addition to a compact design. 

Ecology units are manufactured in various sizes to suit all variants of kitchen designs, prioritizing ease of maintenance as well. They are efficient solutions that seek to eliminate contaminated air through the air ventilation system. It is an eco-friendly solution to preserve and maintain indoor air quality. Grease air removal, in addition to the elimination of contaminated smoke from the ventilation system, is essential to facilitate smooth and efficient commercial kitchen operations. Therefore, ecology units are basically grease trap devices in the kitchen ventilation system.


Listed below are some benefits of ecology units, as listed below:

  1. Incurrence of lower maintenance costs
  2. Cost-effective alternative for other options, such as carbon filters
  3. Reduction of cooking and other kitchen activity odors
  4. Destruction of grease particles in kitchen ventilation systems
  5. Ease of installation of ecology units on existing ventilation systems


Selecting ecology units for kitchens is not a complicated process – varying unit capacity determines the amount of smoke and grease particles that can be dispensed from the air. Ecology units should therefore be selected subject to kitchen requirements.

In commercial kitchens, the type of food to be cooked, air change rates, and kitchen hood size determine the airflow to be handled by the ecology unit. A properly selected ecology unit will meet all kinds of commercial kitchen installations. The main purpose of the ecology unit is to extract the maximum grease particles in the air and vent them through the ventilation hood and out of the building.
