Portable Vacuum Sampler model 4901

Manning Environmental's portable vacuum sampler is the ideal instrument for CSO monitoring, pre-treatment compliance. I&I studies, stormwater applications, NPDES compliance, and general purpose sampling. With its powerful vacuum system, the 4901 is well suited for high vertical and long horizontal draws. No other sampler can compare to this unit's sample volume repeatability and accuracy (0.5% of preset volume) for producing the most representative samples possible. Legendary durability and longevity also make Manning units the most reliable samplers available. This equates to unparalleled value since Manning vacuum samplers have the lowest overall cost of ownership of any automatic sampling system on the market.

Vacuum compressor
Manufactured to Manning's own exacting specifications, this powerful yet compact 12VDC unit is capable of moving 9 gallons of air/min (1.2CFM) which translates directly into high transport velocity. Utilizing advanced thermoplastics in addition to being environmentally sealed to protect its internal components, the need for regularly scheduled maintenance program is eliminated. The incorporation of these and other features into the unit ensures the Maning 4901 will provide years of trouble free service.

Accurate, repeatable sample volumes
No other sampler delivers more accurate and repeatable sample volumes over a wider range of head heights than a Manning vacuum sampler. Absolute accuracy of the 4901 is 0.5% of pre-set volume, giving you the confidence the collected sample will be exact, and the integrity or your sample data will be undisputed.

Transport velocity
Experts and sampler manufacturers agree a critical factor (if not the most critical) in obtaining a representative sample is the sampler's transport velocity. By generating over 1.2 CFM, Manning vacuum samplers produce the highest transport velocity of any commercially available suction lift sampler. This ensures samples collected by Manning vacuum samplers are the most representative possible.

Controller
Environmentally sealed within a NEMA 4X, 6 enclosure, the critical components of the 4901 are protected from the elements. A large backlighted LCD display makes the unit easy to read and program even in dark environments. An ergonomically designed keypad allows powerful programming features to be easily accessed, and data to be quickly entered into and retrieved from the microprocessor-based system saving both time and effort.

Versatile
Manning's portable vacuum unit is capable of taking samples from a wide range of sources -- from heavy influent to critical stormwater or CSO sites. An optional 5/8" ID intake is recommended for applications with potential clogging problems or large solids. This helps to reduce or eliminate expensive downtime. It is also excellent for applications that involve the sampling of sources containing hard organic matter. The material passes harmlessly through the sample tract and into the bottle, preventing expensive repairs and critical failures. Easily transported to remote site applications, or equally at home in a fixed site situation, the Manning model 4901 provides all the flexibility you'll ever need to confidently meet your sampling needs today and in the future.
