BuTech line filters are used in system lines to remove contaminating particles from the system fluid. Upstream filter of larger micron rating than downstream filter to prevent clogging of downstream filter.
Standard materials of construction are 316 stainless steel with 300 series stainless steel filter discs. Available in nominal ratings of: 0.5, 2, 5, 10, 20, 40, and 100 micron.
Micron rating of filter must be specified. To order, complete the catalog number with the desired micron rating, upstream first:
- 20LF4-40/20 specifies a line filter with 1/4" M/P connections, a 40 micron filter upstream and 20 micron downstream.
BuTech sintered cup filters offer maximum filtration surface area for removal of contaminating particles from the fluid system. They may be used in systems which require high flow rates with minimum pressure drop.
Standard materials of construction are 316 stainless steel with 300 series stainless steel filter discs. Available in nominal ratings of: 5, 10, 20, 40, and 100 micron.
Micron rating of filter must be specified. To order, complete the catalog number with the desired micron rating:
- 20SCF4-20 specifies a line filter with 1/4" M/P connections and a 20 micron filter.
