PALL 1220 Open-face Filter Holders - 47 mm, open-face aluminum, 1/pk

This filter holder is designed for air sampling and particulate collection, allowing users to capture airborne contaminants such as dust, bacteria, and aerosols on membrane filters. It is commonly used in environmental monitoring, industrial hygiene, and laboratory analysis.

An open-face design means the filter is directly exposed to the air without an inlet cover or directional flow path. This allows for unrestricted particle collection, making it ideal for ambient air sampling and surface contamination studies.

This model is designed for 47 mm diameter filters, which are a standard size used in air monitoring and laboratory filtration applications. This compatibility ensures easy integration with commonly available membrane filters.

The aluminum body is lightweight, durable, and corrosion-resistant, making it suitable for repeated use in laboratory and field environments. It also helps maintain structural integrity during sampling and transport.

This filter holder can be used to capture airborne particles, microbial contaminants, and fluorescent tracers depending on the filter media installed. It is widely used in air quality testing, cleanroom monitoring, and occupational safety assessments.
