The Stark Expello Air Dryer/Purifier is available from Norman G Clark .
The Stark Expello Air Dryer/Purifier with its advanced micro-glass fibre technology provides a effective, self cleaning, long life filter. The filter automatically purges every 5 minutes. It is thermostatically controlled for year-round efficiency.
The filtering system removes 100% of all solids larger than 1 micron in size and virtually all compressor blow-by oil. The coalescing is achieved by a coil, which allows the moisture contained in the compressed air to be removed.
An audible signal indicates when the filter element needs to be changed. Otherwise no maintenance is required and the accumulated moisture is dumped from the system by the regular operation of the Stark Expello valve.
The system consists of 2-parts; the Stark Expello Air Dryer/Purifier and then the Expello Valve.
It has the following features:
- Low cost maintenance
- High C.F.M. flow rate - 36 C.F.M
- Efficient oil removal
- Efficient solids filtration
- Consistent results
- Small overall size - lightweight
- One size fits all
- Heater options cover all voltage requirements
- Proven efficient over time
Expello Pneumatic Drain Valve
The Expello Pneumatic Drain Valve is fitted to each Stark Air Dryer/Purifier. It is actuated either by an electrical signal or pneumatically by the unloading of the compressor.
The Expello valve can also be purchased independently and used as a dump valve for vehicle wet tanks, accumulator tanks for compressed air or any other part of the compressed air system that requires automatic draining where moisture may accumulate.
The Expello Pneumatic Drain Valve operates by expelling harmful contaminants from the compressed air system with a short sharp powerful blast of air. Heated Expello Pneumatic Drain Valves are available for cold environments where the moisture may freeze, blocking the dump point.
