Koch Multi-Sak Bag Filters for Critical HVAC Environments

Multi-Sak Bag Filters: Durable Filtration for Critical HVAC Environments

When uptime matters, your air filtration choice matters too. Koch Multi-Sak bag filters are designed for high-performance HVAC systems in data centers, healthcare facilities, and commercial buildings where consistent airflow and dependable particulate capture are essential.

Multi-Sak filters use an extended-surface, pocket-style design that helps increase media area, reduce resistance to airflow, and extend service life. That combination can help lower maintenance interruptions, reduce labor tied to change-outs, and support more stable system performance over time.

Why Multi-Sak Stands Out

One of the biggest advantages of Multi-Sak is its balance of efficiency and airflow. The filter is built to maintain stable static pressure throughout its service life, which helps CRAC and AHU systems work efficiently without unnecessary strain.

It is also built for demanding environments. Koch notes that Multi-Sak can be specified with durable galvanized steel or high-strength synthetic frames, and custom sizing helps create a tighter fit with reduced bypass risk in non-standard housings.

Applications That Benefit Most

Multi-Sak is a strong fit for facilities that cannot afford inconsistent filtration or frequent downtime. Common applications include data centers, healthcare facilities, commercial HVAC systems, high-humidity environments, and industrial spaces with heavier particulate loads.

For data center environments, Koch positions Multi-Sak as available in MERV 13–15 configurations, with documentation that supports audit-ready compliance needs. That makes it especially relevant for operators looking to improve filtration without sacrificing airflow.

Multi-Sak Series Overview

Koch offers several versions of the Multi-Sak line to match different operating needs. Series S uses synthetic media and is designed for medium to high efficiency HVAC systems, with options that emphasize low pressure drop and moisture resistance.

Series G uses fiberglass media and is also aimed at medium to high efficiency applications, with low pressure drop and resistance to moisture and humidity. For specialized industrial conditions, Multi-Sak Oil Mist is designed to help capture oil aerosols and heavy particulate loads.
