The RSF and RSW industrial type Refrigerant Strainers with stainless steel screens are designed especially for the protection of Industrial Refrigeration control valves from foreign materials present in refrigeration systems. The fine stainless steel mesh will collect particles as small as 0.009” in diameter (60 Mesh@ 0.0075” wire). Generous available screen area allows maximum dirt capacity at minimum pressure drop. The RSF strainers may be close coupled to Industrial Refrigeration valves having the same flange gasket size.
