PAF 111 – Cabin Air Filter Test System

With the Test System for Cabin Air Filters acc. to DIN 71460-1 (Particle Filtration) fractional filtration efficiency is measured while the filter is continuously loaded with dust at constant air flowrate. The increase in pressure drop across the filter is monitored to establish the dust loading capacity. Both the necessary test rig and the test procedure are according to and are completely described in the standards DIN 71460-1 and ISO/TS 11155-1 for motor vehicle passenger compartment filters.

Test acc. to standards E DIN 71460-2 and ISO 11155-2 can be carried out using Topas Adsorption Test Rig PAF 112 for cabin air filters (air filters for passenger compartments).

For filter tests both acc. to standards DIN 71460-1, ISO/TS 11155-1 and E DIN 71460-2, ISO 11155-2 Topas has designed filter test rig PAF 113 combining all features of test rigs PAF 111 and PAF 112.
