All New Robust Construction and Leak Free Design
AstroHood® S-III RSR-III’s robust construction and leak free feature is due to thicker construction material and continuous welding at all corners.
Designing for complicated parts has become easier, thanks to aluminium extrusion profile. AstroHood® S-III RSR-III comes with multipurpose suspension brackets that can be positioned in any point on the housing perimeter.
Supported Variety Airflow Options and Tools Free
AstroHood® S-III RSR-III can handle different volumetric of airflow with the same filter dimension, without adjusting the filter clamping devices. It is designed with tool free in mind, during new filter installation or replacement and removal of diffuser. The swirl or perforated diffuser are available in powder coated or stainless steel.
More Media Area More Airflow, ePTFE Media available
Revolution test ports designed by our R&D team help us to remove the centre divider, which means an increase in the filter area and airflow. You will save approximately 50% on energy with the new ePTFE media compared to glass fibre and this product is engineered with good chemical resistance, too.
