TM Filters

Knock Out Filters


Too much moisture, whether gas is compressed, used as a sealing media or burned as fuel will have negative impact on the performance and endurance of Turbomachinery Equipment. As a final filtration step, coalescing filters are used to remove liquid aerosols. When gas contains liquids or moisture that exceeds 50% of a coalescing filter capacity a Knock Out Filter is used to remove the bulk of liquid/moisture from the gas. On request TM Filters can deliver filtration products that exceeds API 614 requirements and achieve laboratory grade efficiencies as good as β0,2µm > 1000.

TM Filters deliver high efficiency Knock Out Filters that have low pressure drop and maintenance free operation, except when a filter element is installed in addition. Our Knock Out Filters can be delivered as stand-alone units or as a combination with coalescing filter elements in a complete system.
