    One diaphragm kit for a Whirlwind STA100 Linear Air Pump.

    Whirlwind air pumps provide years of dependable service but due to continual wear over time some pump components may need to be replaced in order to continue to provide the proper air flow. Instead of purchasing a new pump, you may just need to replace some internal components.

    Diaphragm kit includes two diaphragm blocks, two diaphragm heads, one filter pad, and hardware.
