Air filter intake systems for rotary machinery -- Test methods -- Part 2: Cleanable (Pulse jet) air filters prEN ISO 29461-2

Scope

This international standard specifies methods and procedures for determining the performance of cleanable (pulse jet) particulate air filter systems used as air intake filter systems for rotary machinery such as stationary gas turbines, compressors and stationary internal combustion engines. The procedures and hardware in this standard are applicable for filter systems which operating at flow rates within the range of 1,11 m3/s (4000 m3/h) up to 6,67 m3/s (24000 m3/h).

Parameters to be evaluated includes initial efficiency according to ISO 29461-1, gravimetric efficiency during operation, air flow resistance (energy consumption) during pulse cleaning and high humidity environment.
This international standard applies to air filter systems typically designed for high ambient particle concentrations and therefore uses pulse cleaning as a method to operate.
