1. General Details

    Features:

    • High sample flow rates at high ΔP adjustable constant flow rate control
    • Flow rate indication on rotometer, CFM or LPM
    • Rated for continuous duty
    • Minimum maintenance
    • Optional elapsed time indicator
    • Medium weight
    • All units individually calibrated and traceable to NIST

    The Model AVS-60A Portable Air Sampler is a versatile, medium weight, continuous duty, constant flow device. It can be used with filters and cartridges in the collection of airborne contaminates, or as a regulated, positive displacement vacuum supply for continuous air monitors and stack sampling systems. This unit is perfect for jobs requiring 1 to 8 CFM (25 to 225 LPM.)

    The ability of the AVS-60A to maintain a preset sample flow rate is controlled by the unique side-mounted regulator valve. The RADēCO regulator valve is not a bypass design, and therefore the exhaust contains only sampled air. The AVS-60A has the superior ability to compensate for added ΔP across sampling media.

    The sampling flow rate is read out on a side-mounted rotometer that measures the differential pressure across the in-line anodized aluminum venturi. All units are individually calibrated and traceable to NIST.
