Фильтр на замену Weller FT91000042

The replacement filter includes a small silicone hose and connector. This is used by the Zero Smog 4V to measure differential pressure through the filter to indicate when the filter is full.   

The filter also fits Zero Smog EL and TL filtration units as a performance upgrade to the standard filters found in those units. 

The life of a main filter is extended by using it in conjunction with prefilters. Prefilter packs and the Main filter also can be purchased as a set for convenience and at a reduced price (part number FT91000042).
