Summary
This document is a comparison sheet for panel prefilters used in air handling units (AHUs). It outlines the purpose of panel prefilters, which is to protect fine filters and maintain cleanliness by capturing larger particles such as coarse and ePM10 from both intake and recirculation air. The document provides detailed specifications for three different prefilter models, including nominal airflow, efficiency ratings, initial pressure drop, recommended exchange pressure drop according to EN 13053, maximum dust holding capacity, annual energy consumption, and energy class according to Eurovent 4/21-2019. Additionally, it discusses the approximate lifetime of each prefilter under various conditions, the media used in construction, and available frame materials. The information presented is intended to assist in selecting the appropriate prefilter while considering factors such as cost, maintenance, and sustainability.
