AFS-952-55 combines the precise operation of our AFS series with convenient features for industrial and commercial air handling applications. The AFS-952-55 can monitor positive, negative, or differential pressure (flow) of air and noncombustible gases. It is ideal to monitor combustion air, furnace pressure, ventilating blower operation, inflatable structure pressure, fume hood operation, bag house air flow, dirt accumulation in air filters, and heat-transfer air flow. The most common specific application for the AFS-952-55 is as a High Pressure (Positive Pressure) Cutoff Safety Switch for combustion draft control systems where delayed actuation is desirable. The field–adjustable set point range is 0.05″wc to 12.0″ wc with an 8-second (± 3 seconds) time delay relay sequence. The time delay prevents nuisance shutdowns due to normal draft fluctuations. The AFS-952-55 is available in NEMA-1, NEMA-4, and NEMA-7/NEMA-9 enclosures.
