1. Expello Electronic Drain Valveexpello electronic

The Expello Electronic Drain Valve provides increased durability and reliability for constant protection from build-up of harmful contaminants in air tanks on trucks, trailers, buses, RV’s and other vehicles.

Keep in mind that no system eliminates all the moisture from the wet tank all the time.

This drain valve expels contaminants every five minutes of operation with a powerful one-second blast of air. The electronic controls and 50 watt heater provide year round protection. The corrosion resistant construction ensures maintenance-free operation over the long haul. Once installed in place of the manual drain petcock on the tank, the valve’s straight through contaminant flow and self-cleaning design provide air tank draining without daily checks.

  • Automatically cleans air systems
  • Purges moisture and contaminates from air tanks
  • 1 second blast every 5 minutes
  • Compact design fits air tanks on all trucks and buses
  • Replaces manual drain petcocks (never pull another chain to drain the tank)
  • Prevents freeze-ups with 50-Watt heater
  • Prevents brake drum damage
  • Prevents cylinder corrosion
  • Prevents sticking valves and loss of lubrication
  • Reduces noise and vibration due to contaminated air systems
  • Full One-Year Warranty

2. Expello Pneumatic Drain Valve

expello pneumatic drain valve The Expello Pneumatic Drain Valve provides long lasting, durable air system protection. This drain valve expels build-up of harmful contaminants in air tanks on trucks, trailers, buses, RV’s and other equipment with compressed air systems. No system eliminates all the moisture from the wet tank all the time. This drain valve expels contaminants from your air tanks with a powerful blast of air whenever your compressor reaches cut out and at compressor cut in. The 50 watt heater with built in thermostat provides year round protection even in the coldest conditions.

  • Purges every time the compressor cycles (requires actuation line)
  • Compact design fits air tanks on all trucks and buses
  • Replaces manual drain petcocks (never pull another chain to drain the tank)
  • Automatically purges moisture and contaminates
  • Prevents freeze-ups with 50-Watt heater (optional)
  • Prevents brake drum damage
  • Prevents cylinder corrosion
  • Prevents sticking valves and loss of lubrication
  • Reduces noise and vibration due to contaminated air systems
  • Full One-Year Warranty

STARK Air Dryers

stark air dryer Preventing freeze-ups, clogging and corrosion The Stark Air Dryer system helps prevent brake line freeze-ups, clogging, deterioration and corrosion in an air brake system. It removes oil, carbon, dirt, sludge, and gets the water out! These air dryers are both a filtering and coalescing system. They remove 100% of solids larger than 1 micron in size and 99.9% of all compressor “blow by” oil. Moisture is also removed by the filter/coalescer. These units provide clean dry air 100% of the time. The Stark Air Dryer’s efficient space age design of unique vacuum formed glass fibers yields the highest C.F.M. flow rate. After-cooler and desiccant dryers would have to increase their unit size and capacity to reach this level of flow. The Stark Air Dryer fits both the governor and unloader models The basic model fits both governor and unloader controlled air systems making it the most versatile air protection device on the market. It can be used on virtually any mobile application including off highway construction and mining equipment. The Expello Drain Valve located on the bottom of the unit purges any remaining moisture from the system. You have the option of selecting these air dryers fitted with either the pneumatic or electronic valve as described in our drain valve section above.

  • Vacuum Formed Micro-glass Fiber Filter Technology
  • Highest C.F.M. Flow Rate – 36 C.F.M
  • Most Efficient Oil and Solids Filtration
  • Small Overall Size – 6 by 12 inch unit
  • Low Cost Maintenance – replace filter without removing unit
  • “Whistle Stop” element change indicator
  • Best Overall Efficiency
  • Full One-Year Warranty
