Breakthrough Indicator with Auxiliary Filter Trap (BTI AFT)

The breakthrough indicator with auxiliary filter trap (BTI AFT) is a colorimetric filter change indicator that indicate the saturation and exhaustion of carbon adsorbers and filters. It is reliable and cost effect means for protection from exposure to toxic gases and vapors in the work place. Indicator changes color when carbon adsorber, carbon scrubber and filter is saturated with target gases or vapors. Hence alerting the user to replace the exhausted carbon adsorber or filter. The BTI AFT is equipped with auxiliary filter trap to protect the indicating layer from changing color in a highly contaminated surrounding environments. The indicator is 3.5-inch-tall, 1-inch diameter and are easily connected to the ¾ inch female NPT outlet of the carbon absorber or filter using the ¾ inch male NPT threading at the bottom of the indicator.
