This device is an economical dust collector control timer. It is available with 2, 4, or 6
solenoids that will activate the dust collector diaphragm valves. The solenoids connect
to the diaphragm valves with ¼" od poly tubing. This control is simple to operate and is
suitable for small dust collectors. The frequency and duration of the timing functions are
adjusted with potentiometers which are accessed by removing a clear Lexan cover.
Electrical connections consist of a power connection and a two wire connection to the
control. This controller will also operate in "on-demand" mode when connected to a
photohelic differential pressure switch. An input is provided to initiate a post shutdown
cleaning of five pulses per filter.
The models are available standard or Atex certified. Their descriptions are designated
