Pureflo FPM fan-powered terminal filter modules are lightweight unitized low profile units consisting of a fan/motor assembly and a mini-pleat HEPA/ ULPA filter pack, designed to provide unidirectional vertical airflow from tee-bar ceilings. The modules are available in two sizes: nominal 24″ x 24″ and 24″ x 48″, as a standard replaceable unit. Module efficiencies are 99.99% on 0.3 micron particles or 99.9995% on 0.12 micron particles.

Application & Installation Considerations

Pureflo FPM modules are recommended for use in cleanroom applications for fabrication of microelectronics, semiconductors, and medical devices.

The filters in standard modules are table-top replaceable with the entire unit removed from the ceiling. The filters are clamped into the fan plenum against a continuous knife-edge that is embedded into the gel for a leakproof seal. Removal of the filter does not disturb the enclosure. Neoprene gasketed filters are available as an option.

Modules include threaded inserts with ¼″ eyebolts at each top corner for the attachment of seismic restraint wires. Polyfoam gasket material should be applied to the tee-bar surfaces on which the modules rest.
