PRE FILTER

Introduction

Coarse filters are also referred as rough filters available from EU-1 to EU-4 as per European Standards.

Application

Filter particles down to 10 microns with an efficiency of 85% to 95%. The filters can be installed directly in AHUs or mounted in banks.

Media and Its Function

Superior quality non-woven synthetic filter media, sandwiched between two layers of HDPE mesh which acts as a retainer and screens out large particles, thus, preventing them from being embedded in the media.

Construction and Supports

The pleating of the media enhances the filtration area for better efficiency. To eliminate the possibility of even a small amount of dirty air bypass, the media pack is securely bonded to the periphery of the enclosure frame using PU hardener.
