The Cleveland AFS-952-B is an SPDT air pressure sensing switch with a 0.05 to 12.0" W.C. field-adjustable set point range and an 8-second (± 3 seconds) time delay relay sequence.

Applications:

Low Negative Pressure Cutoff (Shutdown Upon Insufficient Draft)
Low Positive Pressure Cutoff (Shutdown Upon Insufficient Pressure)
Low Differential Pressure Cutoff (Shutdown Upon Insufficient Difference Between Two Samples)
Low Draft Negative Pressure Cutoff Safety Switch for Combustion Draft Control Systems

The pressure switch monitors negative, positive, or differential pressure air flow and non-combustible gases. The time delay prevents nuisance shutdowns due to normal draft fluctuations.

The AFS-952 is suitable for industrial and commercial air handling applications. This component is designed for surface mounting on any flat, relatively stable surface free of vibration.

The UniControl Cleveland Controls AFS-952-B and the AFS-952-55-B are both adjustable set point air pressure sensing switches. Both have an 8-second delay and are built in the same housing and thus have the same dimensions. The difference lies in the function with the AFS-952 being a "Low Draft (Negative Pressure) Cutoff Safety Switch for combustion draft control systems" and the AFS-952-55 being a "High Pressure Cutoff Safety Switch for combustion draft control systems."

According to the OEM technical bulletins, the general applications of the AFS-952 are:

• Low Positive Pressure Cutoff. (Shutdown upon insufficient pressure.)
• Low Negative Pressure Cutoff. (Shutdown upon insufficient draft.)
• Low Differential Pressure Cutoff. (Shutdown upon insufficient difference between two samples.)

and the general applications of the AFS-952-55 are:

• High Positive Pressure Cutoff. (Shutdown upon excess pressure.)
• High Negative Pressure Cutoff. (Shutdown upon excess draft.)
• High Differential Pressure Cutoff. (Shutdown upon excess difference between two samples.)
