  • Drain TechnologiesCompAir utilizes the latest in drain technology to meet all of your system needs. Although CompAir offers a variety of drains, there are three major drain technologies, Pneumatic, Electronic Demand and Timed Electric, in the product offerings.

    Pneumatic

    Pneumatic drains are a great option because they permit installation anywhere without concerns for electrical safety issues. Pneumatic drains are powered by air, not electricity, so they are ideally suited for remote or portable applications. They are also safe to operate in any hazardous area. Drains offered by CompAir are also zero-loss, meaning no compressed air is lost during the drain process. This results in energy savings.

    Electronic Demand

    Electronic Demand drains offer a great amount of installation flexibility and will reduce the amount of energy consumed. They operate based on the level of demand, not on a specific time setting that does not take demand into consideration. When the level of condensate in the reservoir rises to its maximum level, a capacitive sensor activates and the system of discharging the condensate begins. CompAir's zero-air-loss electronic demand drains ensure reliable condensate removal and that costly compressed air is never lost.

    Timed Electric

    Timed Electric drains operate by utilizing two timed settings that a user can program according to their application and drain needs. The drains have one timer that is set for the interval between each time the drain opens. The second timer is set for the amount of time that the drain is open. During the draining process there will be a minimal amount of air lost.

    Where Are Drains Used?CompAir condensate drains ensure manufacturing process and finished product are not contaminated by bulk liquids and oil. Proper drain installation is a critical component in a well designed CompAir air treatment system.

    1. Separators used downstream of after-coolers remove large amounts of condensate from the compressed air stream. They are normally integrated into a compressor package or are placed directly at the compressor outlet. These separators are designed to effectively remove high volumes of liquid contamination.

    2. Receiver tanks utilize drains installed beneath the tank.

    3. Filters utilize drains to dispose of liquid oil and water which has been separated from the air stream by the coalescing filter element.

    CDX Electronic Demand Drain

  • Using Drains Saves You MoneyInstalling automatic condensate drains has several benefits for every compressed air system

    Eliminates daily man-hours required to walk the factory and manually drain air lines and equipment

    Eliminates daily man-hours required every morning to purge the air lines of condensate before work begins

    Prevents the receiver tank from filling up with condensate and causing the compressor to short cycle.

    Zero loss drains save on wasted compressed air created when valves are cracked open to purge the air lines of condensate

    Ensures timely and effective condensate removal during working hours to protect end products and processes from contamination

  • CMD SeriesThe CMD Series are level actuated, pneumatically operated, zero-loss, automatic condensate liquid drain devices for use in discharging collected liquid from a compressed air system. It is recommended that the CMD Series drains are used with air receivers, drip legs, aftercoolers, separators, dryers, and filters.

    Features & Benefits Operating temperatures: 35150F

    Operating pressures: 10500 PSIG

    Models offered with top or bottom inlet connection

    Economical drain for light to heavy duty service

    Discharge rates of 0.324 gallons/hour

    Discharge port designed to prevent clogging

    OperationSee Figure 1

    1. Float held in place by a magnet.

    See Figure 2

    2. Condensate rises. Buoyancy of float overcomes magnetic force.

    3. Float arm rises. Pilot valve opens.

    4. Compressed air enters cylinder. Piston moves up. Discharge port opens.

    5. Condensate level falls. Pilot valve closes. Back pressure bleeds off.

    6. Air pressure moves piston down. Discharge port closes.
