Functions and Features of Filter AHU_2

Air handling units are the core of any HVAC system. Their filters are crucial for ensuring high indoor air quality (IAQ) in any environment, including commercial and residential spaces.

As a result, the key functions of air handling units and their filters include:

• Ventilation

  This is the process of supplying fresh air and removing stale air from a building. An AHU gets its air from outside and circulates it inside. Stale air is, therefore, constantly replaced with fresh air.

• Temperature Control

  The air handling unit filter is part of the larger HVAC system. As such, it regulates and maintains the ideal temperature within a building. This is achieved by either cooling or heating the air before it is circulated inside.

• Humidity Control

  Some AHUs come with dedicated systems for controlling humidity. Such units filter humidity from the air in order to maintain the ideal indoor moisture levels. This is important for both comfort and the integrity of a building's structure.

• Air Filtration

  The filters used in air handling units are the front line in defense against pathogens, particulates, and any other contaminants. They trap various contaminants in order to ensure the delivery of clean air to indoor spaces. The filters are classified by efficiency, with higher MERV ratings indicating better filtration. The choice of filter depends on the application, with HEPA filters being used in cleanrooms and hospitals.

• Air Distribution

  The AHU is responsible for the proper distribution of air within a building. It uses fans to push air through duct networks. The air is then delivered to different rooms and spaces. The entire process ensures that every part of a building receives the required amount of air.

The air handling unit and filter also come with various features, including:

• ECM Motors

  This stands for electronically commutated motors. These motors have a brushless design. They are commonly used in air handling units because they are energy efficient. ECM motors provide variable speed operation. As such, they can be used to adjust the airflow and energy consumption of the air handling unit.

• Variable Air Volume (VAV)

  These are controls that offer customized airflow to different parts of a building. They are dependent on the occupancy and specific needs of each room. For instance, some rooms may require more air than others. Variable air volume systems offer this flexibility. This is because traditional systems deliver the same amount of air regardless of the needs of the room.

How to choose filter ahu

Choosing the right filters for air handling units requires considering several factors to ensure optimal performance. Here are some of them:

• Determine the airflow capacity

  The first thing to consider when choosing an air handling unit and filter is determining the required airflow capacity. This is the amount of air that must be circulated to maintain proper ventilation, temperature, and humidity. Once this is done, choose an AHU filter with an airflow rating that matches or exceeds this capacity.

• Identify the source of contaminants

  Another factor to consider is the types and sources of contaminants present in the environment where the AHU is used. This can include dust, pollen, mold spores, smoke, and other particulate matters. Identifying these will help select filters with the right efficiency ratings to remove these contaminants.
