When Should I Replace a Cleanroom Fan Filter?
HEPA & ULPA Filter Replacement
Optimal Fan Filter Efficiency and Cost Savings
Yes, extending the operating life of a filter reduces overhead and maintenance costs. Longer filter life cycles increase energy use as the filter clogs with particulate. The energy penalty to move air through a dirty filter often outweighs the cost of replacement.
Operating a filter to its most extreme boundaries rarely has an economic advantage. Maximize performance and filtration investment by replacing dirty fan filters once the pressure drop has doubled from the initial installation value.
Fan Filter Servicing
Reducing Air Handling Noise & Cleanroom Footprint
MicroSound Fan Filter Units include a 99.99% efficient HEPA filter, 30% ASHRAE pleated type prefilter, seismic clip suspension points, and a safety switch which disables the unit while servicing. A solid state variable speed control with RFI suppression allows fine-tuned airflow.
Critical applications may require 99.99% efficient HEPA or 99.9995% efficient ULPA filters. An anodized aluminum frame holds the media which is protected by a diamond pattern white epoxy coated steel grille. Once the unit is removed from the housing removing and reinstalling the filter is , placing on a bench, removing and replacing the filter and re-installing the unit in the ceiling.
