Topas ALF 114 filter test system

The Topas ALF 114 filter test system has been specially developed for air filter testing in accordance with ISO and international standards. Filter samples can be easily installed into the rotatable and movable duct sections. A filtrated air flow is loaded with particles, allowing us to acquire and analyse data on the efficiency of each filter. 


The test duct is divided into six duct sections and constructed airproof. The air is sucked in at duct section 1 and blown out behind the blower. The pressure measuring facilities in duct section 2 to 5 determine the differential pressure of the filter.

What We Test For:

Flow Bench Testing

Flow bench testing ensures our HVAC filters deliver optimal airflow, energy efficiency, and reliable performance. By simulating real-world conditions, we verify filtration efficiency, pressure drop, and consistency. This guarantees every filter meets strict industry standards, so you enjoy cleaner air, lower energy costs, and dependable quality - tested, proven, and trusted.
