AFA(E) Series
The AFA series is designed for air conditioning and commercial
refrigeration applications requiring angle conguration SAE
connections. The AFA is ideal for those applications requiring
compact size combined with stable and accurate control over
wide load and evaporator temperature ranges.
Specifications
• Maximum working pressure: 700 psig
• UL/CUL le number: SA 5312
Options
• External or internal equalizer
