High Temperature Filters

HYGIENO FILTERS manufactures metal frame separator HTHF SERES HEPA filters for applications with high temperature requirements up to 1,000ºF (540ºC) for exhaust air only and 500ºF (260ºC) for supply air. High Temperature Filters are available with either a gasket or fluid seal.   

Each HEPA filter has a minimum efficiency of 99.97 % on 0.3 microns when tested at rated capacity on a Q-107 Test Rig. Each filter is challenged with an approved nearly monodispersed oil aerosol of 0.3 micron size and by measuring the upstream and downstream concentration of these particle with a light scattering photometer, the penetration can be determined and the efficiency can be calculated.
