Casella-USA-09-10-12-body.jpgThe company’s ruggedized TUFF air sampling pumps are made for extreme environments.

Extreme environments can expose workers to dangerous airborne particulates and vapors, such as lead, mold or asbestos, or a variety of organic or synthetic chemicals. Sample pumps must be accurate and rugged to survive in all kinds of work environments while reliably collecting physical samples for further analysis.

To meet this critical need, Casella CEL offers its TUFF™ line of personal air sampling pumps that feature a sealed case with over-molding that protects it from damaging moisture, extreme temperatures, solvents, and impact.

With a flow range from 5 ml/min to 4.5 l/min, TUFF pumps are ideal for a wide range of occupational health and safety applications - from simple abatement sampling to more specialized industrial hygiene monitoring of dusts, fumes and gases. All pumps incorporate a proven efficient double-acting diaphragm mechanism with precise digital control to give the user excellent real-time flow control and true stability across a wide range of sampling media.  Pump operation is guided by an intuitive user interface displaying real time flow, sampled volume with run duration, as well as a battery "fuel gauge" and alarm for flow or battery fault conditions.

Safety and health professionals can specify the features they need by selecting the standard TUFF model, the TUFF Plus, or the TUFF Pro. By choosing a 1.7 or 2.7 Ah battery pack, 3 or 4.5 L/min maximum flow rate capacity the user can optimize performance and price to meet their exact needs.

Every TUFF pump uses detachable and field-swappable NiMH battery packs ensuring maximum uptime. Typical run times of more than 30 hours (depending on media and flow rate) make them the perfect choice for longer sampling periods.

Casella TUFF air sampling pumps meet applicable NIOSH and EN requirements for personal sampling pumps. Intrinsically safe (IS) models are available for use in hazardous locations. 

Casella offers a full line of accessories including sampling heads, impingers, filter media, and sorbent tubes, plus rotameters, and calibrators for flow verification ensuring compliance with accepted sampling methodologies.
