PAF 111 Test System

PAF 111 test system for testing particle separation of air filters for passenger compartments (DIN 71460-1, ISO/TS 11155-1)

With the test system for cabin air filters acc. to DIN 71460-1 (particle filtration) all relevant filter performance parameters such as differential pressure drop, gravimetric or fractional filtration efficiency and dust holding capacity are determined.

The setup and configuration of the test system as well as the required test procedures are described in the standards DIN 71460-1 and ISO/TS 11155-1 for motor vehicle passenger compartment particle filtration.

Tests acc. to standards DIN 71460-2 and ISO 11155-2 can be carried out using PAF 112 test system for adsorptive cabin air filters.

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