F6 Air Intake Filters and Filter Silencers Air Intake Filter and Filter Silencer The Series F6 Air Intake Filter and Filter Silencer is designed to mount directly on the inlet of an engine, blower or compressor. It will provide db to db noise reduction and the paper filter media has an efficiency of 99% on 1 micron particles. SERVICE LIFE & CLEANING: The service life of the element is dependent upon the surrounding environment and cannot be predicted. To prevent COLLAPSING of the filter element, STODDARD SILENCERS recommends the differential pressure across the filter element NOT exceed 1 inches of water column. Positive indication that the element requires cleaning or replacement can be provided with STODDARD SILENCERS model A0- Pressure Drop Indicator, at an extra charge. To extend service life, rap element gently to dislodge accumulated dirt. An alternate method is to direct compressed air ( PSIG max) through the element opposite to the direction of air flow. THE FILTER ELEMENT MUST EVEN- TUALLY BE REPLACED.
