A & AI Series Float & Thermostatic steam traps are for industrial service from 0 to 175 psig (12 bar) and feature a balanced pressure phosphor-bronze type bellows caged in stainless steel. A & AI Series steam traps are designed for service on heat exchange equipment where there is a need to vent air and non-condensable gases quickly.
The AI Series features the convenience of in-line connections with the same rugged internals found in the A Series.
